DJI Mini 2 Review
Mini drone under 249g with 4k video
I had the original DJI Mavic Pro a few years ago. I enjoyed flying the drone, but sold it after a year as it got less and less use. The main reason was that it wasn’t easy to carry around in addition to my camera. I like the first DJI Mavic Mini, but it didn’t have 4k recording. Mini 2 finally seems to have checked all my boxes, so I got one in Fly More Combo.
What’s in the box
Body
The whole kit (drone, controller and batteries) weights in at 886g in total, lighter than a full frame camera. The kit can fit into the same space in camera bag as well.
Image Quality
Still and Panorama modes
The still image quality is ok in daylight. There is not a lot of details captured with only a 12MP 1/2.3” CMOS sensor. The photos look great on phone, but can see noticeable noises in full size even at base ISO. The quality generally reminds me of cellphone picture before computation photography.
The dynamic range is pretty narrow with the 1/2.3” sensor. I really recommend shooting in RAW as the JPG color is not very pleasing and tends to blow out highlight on white buildings. There is also a AEB (Automatic Exposure Bracketing) mode that will takes three shots at 0 then +/- 2/3 EV. These are saved as individual files that need to be merged in post. I wish the bracketing range can be adjusted to capture a wider dynamic range.
Next, there are three different panorama modes that shoot multiple shots then stitch together within the DJI Fly app. First is 180 deg, which the drone will shoot 7 shots horizontally. The final image stitched by the app is 6989 x 1339 pixels, much lower resolution than expected. I find this really weird, since a single shot is already 4000 x 3000 pixels. It is best to just use the mode to take the pics, then merge in Lightroom using the raw files. I was able to get 12856 x 2333 pixels out of the same group of shots, almost 4x as much pixels. The resolution difference can easily be seen in the full size image. On the other hand side, the default mode does better job at keeping the exposure even.
Second is a 9 shots mode, basically taking them in 3 x 3 grids and create a wide shot. Just like before, DJI stitched is much lower resolution (4819 x 3739 pixels) than Lightroom (10085 x 7662 pixels).
Third mode is a 26 shots mode that shoots all around the drone like a 360 degree camera. The shots are stored as individual images in a folder and a HTML sidecar file. The easiest way to process and view the image is to share on Sky Pixel within the DJI Fly app: Link
Video
The drone can shoot 4k30p at 100Mbps. The quality is quite good. There are also a few QuickShot (autonomous drone shots) modes available to make some cool camera movements. Below is some sample footage with straight out of the drone color:
One of Mini 2 weakness is that it does not have Active Track (Link), which is on every other DJI model. This is probably because Mini 2 does not have forward and side vision sensors for obstacle avoidance. This omission is not very consistent, as the Quickshot functions use object tracking as the drone moves anyway. It should at least have a crippled spotlight mode with fixed drone position. This feature would have been useful to have the camera tracking ferries approaching pier, or car on the road.
Usage Experience
The drone is easy to carry and can fit into the same bag space as a full frame camera with a standard zoom lens. The controller is a bit beefier than expected but is comfortable to hold. It is clever how the sticks is removable, and the cables are neatly tucked under the phone holder/antenna for easier packing. It is great to see everything uses USB-C to charge.
I have flew this drone in a couple of occasions. The whole experience has been greatly improved compared to the Mavic Pro days. The DJI Fly app user interface is easy to understand and responsive. The set up process is painless, and the drone/battery firmware updates are pretty quick.
I also appreciate the map functions that show nearby spots and flight restrictions as it is hard to tell whether there are any helipad nearby. However, beware that this map does not cover all the local restrictions. For examples, some local parks do not permit flying, but are not marked on the map. Therefore, it is best to check for signs/local regulations before take off. DJI HK also gave me a pamphlet on local drone regulation, so it is nice to see they try to be responsible.
The battery last about 25 to 30 mins, and is more than sufficient as I tend to have shot all I wanted by 15 mins at a location. I also rarely use all three batteries in a day trip. The controller battery also lasts a long time as well.

Laowa 9mm f/5.6 FF RL Review
Widest Rectilinear Full Frame Lens
I bought this lens because I was really interested to see what is it like to shoot with a 9mm lens. This is such a unique lens that I broke my habit of buying only auto focus lens.
What’s included:
Inside the box, the lens comes in a plastic draw string bag with a plastic body cap, and a metal lens cap. There are sometimes promotion that will include a 100mm filter holder for free, which is a great value as it is necessary if you want to mount any filter. However, I did not wait for the promotion so cannot comment on the filter holder.
Body
There is no dust and weather sealing on this lens. There is also no white marker on the side of the barrel like other Sony E-mount lens to line up with the body. A bit more attention to detail than just switching the mount would be great.
Image Quality
This lens aperture starts from f/5.6 to f/22. Below is a comparison on different aperture with the A7RIV. The camera in program modes consistently under exposed, I had to bump up the exposure by 0.66 stops. Since there is no metadata, the shot at 1/125 is f/5.6, 1/100 is f/8, 1/50 is f/11. There is not much additional light being gathered from f/5.6 compared to f/8, just gathering around 1/3 stops more. For sharpness, the center is ok and the corner is soft. I don’t see any significant improvement stepping down. Please look at the sample photos (you can click on the pic to see a larger view) and draw your own conclusion.
Shooting Experience
The lens is really fun to shoot with, and it always amazes me how wide the view is. There are a lot of “impossible” shots that can be made with the lens, and even normal objects are fun to shoot again with this lens and get a fresh perspective. Manual focus is not a problem with such a wide angle lens, I just focus at 1.2m most of the time and it is fine.
However, tilting the camera slightly up or down would dramatically affect the image. There are times where the image looks really normal, but also times where the image is really weird. Another things to watch out for is what object is at the edge/corner of the frame. Similar to other wide angle lens, definitely need to make sure nothing is cut off/included by accident, or stretched too much.

Sony A7C Review
Smallest Full Frame Camera with EVF and IBIS
I have pre-ordered the A7C and received it the first day it was released here in Hong Kong. The reason for buying it is that I wanted a small body that is compatible for my existing lens. I ordered the silver body kit with the new SEL2860, which was reviewed here.
What’s in the box
Body
Image Quality
Shooting Experience
I have used the A7C for a couple of weeks. The first thing I noticed was the small size and light weight. The difference of 150g seemed small on paper, but quite significant in use. The 28-60mm kit lens pairs well with the body, and A7C with the kit lens weights about the same as A7RIV body. I enjoy carrying the A7C walking around the street or hiking. The fully articulating screen is useful for selfie or shooting at low angle.
There are a few obvious sacrifices made to keep the body compact. The lack of front dial took some time to get used to. It is also missing the joystick to move AF point. I mostly use AFC real time tracking with center focus area and just focus then recompose. This doesn’t cause a lot of problem with me, but will be annoying for some people. EVF is worst than A7RIV, but is good enough for framing. However, the lack of eyecup means that light would leak around the view finder when shooting against bright light. Single SD card slot is not a major problem to me as a casual shooter, but I understand a lot of professional would be concerned about this.

Sony FE 28-60mm F4-5.6 Review
SEL2860 - Kit lens for the new A7C
What’s included:
I got this lens from the A7C (reviewed here) kit, not sure what it will come with in a retail box. There was nothing included other than the lens cap and the end cap.
Body
This lens is a collapsible design, so will have to zoom out from park position to 28mm before it can be used. The body will give you a warning message when the lens is still collapsed. The length of the lens is 45mm collapsed, and about 70mm when extended to 28mm focal length.
Image Quality
This is a variable aperture lens, with aperture starting at f/4 at 28mm and quickly narrows to f/4.5 as soon as you turn it. It drops to f/5 right after 35mm, then finally to f/5.6 after 40mm.
Below is a comparison on different focal lengths shot with the A7RIV. First with 28mm comparison, the center is sharp wide open at f/4, then not seeing much difference as I stepped down the aperture. The corner is soft at f/4, and gets better but still soft at f/8. The wide end seems to have weak corner.
35mm comparison, starting at largest aperture @ f/4.5. The center is sharp already, and not much change stepping down the aperture. The corner is a little soft at f/4.5, and improves a little at f/8.
50mm comparison, starting at f/5.6. Just like before, good center and soft corner wide open. The corner gets better at f/11.
60mm comparison, starting at f/5.6. Center is good and soft corner wide open. Corner gets better at f/11.
VS 24-70GM
It is quite difficult to tell how good this lens is unless compared against another lens. I have used the 2470GM as baseline for comparison on 28mm and 50mm shooting at f/4 and f/5.6. At the wide end, the center is pretty similar and the GM has better corner. On the telephoto side, GM has better center and corner.
Please look at the sample photos (you can click on the pic to see a larger view) and draw your own conclusion. I find it hard to find significant fault on the SEL2860. The performance is pretty consistent, and only weaker on the corner. Given that this is only a kit lens and its compact size, I am impressed with the performance.
Focus Breathing and Parafocal Test
I have tested these in manual focus with the A7C. I am not a video shooter, but I don’t find any significant focus breathing at 28mm and 60mm. It also seems to be parafocal as well, but it is hard to tell with f/5.6. Please see below sample video:

Sony ZV-1 VLOG Camera Review
ZV-1
I bought the ZV-1 at launch because I wanted to get more into shooting more videos. I have enjoyed the RX-100 series before with the small size and great image quality. The new flip screen, new hot shoes mount, and paired with the old RX-100 V lens makes it an interesting option. I will go how the ZV-1 in both still and video sides.
What’s included
Body
Image Quality
First lets look at wide end at 24mm. The centre is quite sharp already wide open, gets better at f/2.8, then soften up at f/8. Corner is quite soft across the range, and best at f/4.
Next at 35mm, the center is sharp wide open, and get a little better at f/4. Corner is a bit soft, and best at f/5.6.
At 50mm, the center is a little soft at f/2.8 with some purple fringing going on. It gets much better at f/4. Corner is better than at the wide end, but still soft at f/2.8, and is good at f/4.
Finally 70mm. The center is sharp with a bit of purple fringing, and the issue is gone at f/4. Corner is already sharp wide open.
Still Shooting Experience
It is quite nice to carry such a light and compact body compared to a full frame camera. The grip is useful, and provides more confidence when handling the camera. The flip out screen is nice to compose at various angle. However, glare is an issue under the sun. The reduced numbers of control dials/button slows down the process as I often has to go to function bar to change settings. The Eye AF and continuous tracking works great. It is not as sticky as the A7 series, but provide good result and easy to use. Background defocus function works great in still as well, and is useful in program mode to blur out the background without having to switch to aperture mode.
There are a few annoyances with the ZV-1. The zoom toggle is hard to trigger to get the exact framing you want. It either goes too much or too little. The biggest problem is the blurry pictures. The ZV-1 light weight body with no EVF, which makes it a unstable shooting platform. Holding the camera at arm’s length is shaky, and have to be careful when pressing the shutter button.
Video Shooting Experience
The ZV-1 shoots 4k 30p 8 bit video. It has different picture profile, such as HLG, SLOG2 and SLOG3. All the advertise video functions work well. I have tested them all on my YouTube Cantonese channel. Out of all the new features, I find the product showcase mode most interesting. It automatically focus on closest subject in the center of the frame even if Eye-AF is on.
Active steady shot stabilization uses the gyroscopic data, which crop in the image a bit. The alternative way to use the metadata is to use Sony’s Catalyst Browse software in post. From my experience (My Comparison Video Here), the result is better than pure software solution like in Resolve. However, it is not a substitute for a proper Gimbal, especially you can pair the ZV-1 with the tiny Zhiyun M2 gimbal. The new mic setup with the DeadCat windshield is an improvement compared to typical built in mic in cameras. However, it really is not the same level as a separate shotgun or LAV mic. I have used Rode Wireless Go for the small size and easy to use wireless lav mic system.
I am not a pro videographer, so I really enjoy ZV-1 trusty auto focus and the selfie screen. The selfie screen makes framing the video much easier than the previous tilting screen. The lens at 24mm is a bit too tight at times, and it would be better with a 20-50mm lens. A wider lens would be much more useful for vlogging. The battery life is acceptable, and luckily it can be charged with Power Bank via micro USB. A weird issue is that the exposure/white balance seems to shift randomly. I was under the same setting/lighting condition, one video would be normal then the next would be too warm. This happened a couple of times to me, so best to set the white balance manually orcheck the footage after shooting.
Conclusion
The ZV-1 is a great little video camera that can gives excellent result. It is great for casual video shooting with the selfie screen, trusty autofocus, and different features for vlogging. There are some compromises that makes it feels like a part bin camera. First is the ancient micro USB, then the 24-70mm lens used in RX-100 V. Even though the lens perform great, I think vlogger would prefer ZV-1 with a wider lens. Another crazy idea would be to put the A7 Z battery in the grip.
However, it is still a great compact camera for casual vlogging user at the price point. I am happy to see flip screen finally show up on Sony camera, and it is now on the A7S3 and A7C as well. The video features are useful, and I hope to see more use on the gyroscopic data in the future.
For still shooters, the RX-100 series remains the better choice with the EVF and additional controls. There are design choices on ZV-1 that sacrificed the usability for still shooting. I will be interesting to see how Sony updates the next RX-100.

Sony FE 90mm F2.8 Macro G OSS Review
SEL90M28
What’s included
There is the lens, hood, caps, manuals, and a soft carrying case in the box.
Body
Image Quality
Below is 1:1 comparison on different apertures, and these are shot on the Sony A7R4. First, let’s look at the center:
The lens is sharp at the center, even at f/2.8. It gets better as the aperture is stepped down, with no noticeable difference between f/5.6 and f/8. Next, onto the corners:
The corner is a soft at f/2.8, and improves as the aperture is stepped down. At f/5.6 is very good, but f/8 has more textures on the building walls.
Conclusion
The 90mm macro is an excellent lens, and should be considered if you are interested to shoot macro photography. Its focal length provides a good working distance for shooting macro and products. In fact, it is what I use to shoot most of the product shots on the website. The build quality is great, and the size/weight is reasonable to bring around. The push/pull focusing ring is an interesting design that is practical as well.
It offers great image quality, and is really sharp in the center. I am a bit surprised at the soft corner at f/2.8, as this is often mentioned as one of the sharpest lens on Sony E mount. However, macro often requires stepping down the lens to get enough depth of field anyway, so this is not an issue.The focus speed is acceptable, and using the focal limiter helps on it as well. One thing to watch out for is the focus motor makes loud whiny noise when in AF-C.
There are other macro options on the market, but they are all manual focus lens. The 90mm Macro having autofocus makes it a more versatile lens for day to day shooting as well. However, I would not recommend buying this unless you really need a macro lens. I will review the Sony 85mm F1.8, and do a comparison between the two to explain why.

This is a variable aperture lens. The aperture starts at f/4.5 at 70mm, f/5 at 85, then f/5.6 starting 160. Below is a comparison on different focal lengths. First with 70mm comparison, starting at largest aperture @ f/4.5. The center is a bit soft wide open, and gets better as the aperture is stepped down. The corner is soft with noticable chromatic aberration until f/8.
100mm comparison, starting at largest aperture @ f/5. The center is good wide open and gets better as the aperture is stepped down. The corner is still soft until f/8.
135mm comparison, starting at f/5, The center is good already wide open. However, the corner is quite soft.
200mm comparison, starting at f/5.6, the two lens are really similar at center and corner. No significant improvement at f/8 at 2:1.
300mm comparison, starting at f/5.6. The center and corner are good at 5.6. I feel this is the strongest focal length of this lens.

Sony FE 100-400mm G Master Review
With comparison to Sony FE 70-300mm G
Introduction
I had been using the SEL70300G for a few years, since i got the A6500. I was not interested in shooting telephoto until I have the 2nd body and started shooting landscape, birds…etc. I enjoy the additional reach beyond the 2470GM that I usually use. However, I was never impressed by the IQ of the 70300G, and decided to treat myself with the 100400. This review will focus on the 100400 and compare it against the 70300G. All pictures here are shot with the A7R4.
I was deciding between this lens or the new 200600G. After handling them both in the showroom, I was more comfortable with the 100400GM size and weight. A teleconverter can be added if more reach is needed. Another reason was the pseudo macro ability of this lens with 0.35x magnification ratio @ 0.98m versus the 0.2x @ 2.4m minimum focus distance on the 200600G.

200mm comparison, starting at f/5.6, The center and corner is good already wide open, and gets better at f/8.
300mm comparison, starting at f/5.6, center and corner are good. No significant improvement at f/8 even viewing at 2:1.

Sony A7RIV Review
I was very excited when the A7R4 was announced in July. I have always enjoyed my A7R3, but was curious on the real time autofocus system on the A6400 and A9. I immediately jumped on the preorder and got one from Sony Hong Kong at launch.
What’s in the box
Body
Image Quality
Autofocus
The most significant change is the new real-time tracking auto focus system, which was first implemented on the A9/A6400. I now shoot majority of the time in AFC tracking mode whether the object is moving or not. You can see the details on this very useful video from Dpreview. Autofocus is very sticky in most situation, able to keep track of the object even with complex background or challenging light. It is also very simple to use, just put the focus point on the object and half press the shutter. Eye-AF on animal and human works very well, and helps a lot in using large aperture lens to nail the focus. There are tons of video comparing the performance on Youtube, I have briefly compared EyeAF against Fujifilm, and Sony does have a noticeable edge over it.
