I am going for a small trip for wild life photography. Itwas great to understand the modes for bird eye auto focus...Thank you for the amazing video.

Thank you for a great video that explained many details in a manner that I was able to follow. The charts presented have very good information for making comparisons. The Photos also made a great presentation. I will apply many of your recommendations for setting up a menu for bird, animal and sports action photography.

Thank you for the thorough and great review! Great camera, interesting how AI autofocus is lagging behind the „normal“ autofocus considering birds in flight. I personally think around 40MP to 50MP enough, but getting 26MP in APSC crop is really impressive!

started shooting the A1 at intro. certainly an upgrade over the A7r4 I was using. shoot mainly wildlife, so the autofocus was game changing. spent about one second debating the upgrade to the a7r5 at intro. yes, I consider it an upgrade for not just the sensor size, but the other features you mention in your video. today the field kit is the 200-600 on the A7r5 and the 100-400 on the A1. birds in flight is a specialty that has many variables and the autofocus/tracking falls pretty to many of them. flight with a bright sky background is wildly different from an owl flying in a dark barn. my latest experience with the A7r5 was pretty remarkable. owl flight from the back of the dark barn to the lighted door. no time to bring the body up to frame a shot. just pointed the lens like a shotgun and followed the bird shooting one burst. 59 shot burst had 12 printable owl images, 20 unprintable, rest had no owl in the frame. what was amazing was once tracking was established, it recovered after scanning past rafters with the owl behind it. you don't go into a barn planning to shoot like this, but with the A7r4, I would have gotten zero printable shots. congratulations on a fine video. it was very informative.

I did a very simple test with eye af on A1 and 7R5. Close range wide open continuous focus on eye then rapidly move the camera and shoot a burst. Beyond a certain speed, sensor read time causes missed focus on A7R5. I think AI cannot predict direction and if it did, it could compensate slightly and adjust after missing. The A1 burst has 90%+ keeper rates on this test. A1 much better when you have relatively fast focus changing action towards or away from camera camera. A7R5 is fabulous but sensor readout is the achilles heel and depending on subject matter it will affect you.

For portraits af speed doesn't really matter nor frame rate so A1 is overkill. For street photography, A1 is silent ninja with very high speed and performance in catching once in a life time shots

I use the A7iv for sports and actually focused pics rate is ridiculously low (10% fully focused, about 70 % acceptable) while tracking in the EVF is always great. My understanding is that tracking can spot a face out of a misfocused image and show the little frame in the EVF. But actual fine focusing requires contrast. This is based on the high success rate on faces with lily white skin and dark eyebrows, wrinkles, glasses with thin frame. Whereas blond eyebrows and light eyes are repeatedly misfocused.

In short - it's more expensive, the settings are more complicated, the AF is the same (or worse) and there is no change in IQ. Doesn't sound like a great deal, with only advantages being a new hinge for the back screen and higher resolution EVF.

Great review as always. Thanks! I am surprised by the low success rate for BiF. Wonders if this is true also for the prime lenses since I have better results with the 400 mm 2.8 than with the 100-400 mm 4.0-5.6 with the A1.

Don't ask me what happened: suddenly the AF became lethal. Not like the A1 I've tried this summer (that is another planet), but really consistent. Nothing comparable with A7x previously.

Interesting and well done video. Giving a camera lots of features is always going to cause problems for the user, especially the new user. When it comes to AF you are correct it's a relatively complex area with the A75R as there are a number of interrelated settings that influence performance. Now a year on with the camera currently at 2.01 and the 200-600 on 3.0 have you noticed any change in performance? I have to say I tend to put down missing the shot to the inadequacies of the guy holding the camera. I would like to hear any new thoughts you may now have given time has passed and firmware has been 'improved'. we hope. Incidentally Ive had the A7R5 for 14 months. Lets be honest it does take time to become acquainted with a new camera and with a complex one like the A7R5 its a task. Its certainly no a plug and play camera.

Thank you for this review that I should of waited before purchasing the A7RV and falling for the marketing hype on the AI. Though I do not shoot BIF I experienced the inconsistent AF lock when taking multiple shoots with lower keep rate than the A7IV. The explanation on the AI. processer is best explained here over all the reviews I had watched. It's accurate in "RECONIZEING" the subject and not necessary "100% LOCKING ONTO" the subject when the shutter is pressed. It's like the left brain is not talking to the right brain in this camera or like an ADHD camera to me which does give me good keepers only when the subjects are not moving too fast at low fps. I do miss the Fuji X-H1's sweet mechanical shutter sound while facing rolling eyes and complains in indoor quiet events and weddings when using the much better Eye C-AF on Sony A7 systems. Should just got the A1 instead as I find myself having the LCD facing the camera body in closed position 95% of the time since the EVF is so good.

@MathieuGasquetMirrorLessons

13 күн бұрын

You don't really need stabilisation for birds in flight, especially when using fast shutter speeds like 1/2000s. 8 stops of stabilisation is most likley valid for much shorter focal lenghts. Also, don't forget that it's not just IBIS but you have the lens' OIS involved. You can keep Steadyshot On if you prefer, my advise would be to use Mode 3 on the lens (if available). With Mode 3, the stabilisation effect in the EVF is active at all time, so you don't get that ackward jerk when you half-press the shutter button, which can be quite severe with telephoto lenses.

Wow! Very interesting Mathieu. You just confirmed my impressions. Your results for BIF is the same as mine. I moved up from the A74 because of the "improved" AF but found little to no improvement. Naturally I assumed it was me. I do appreciate the 26mp in crop mode compared to the 14mp with the A74 though. I also agree regarding set up. The menus are so deep and nuanced that more often than not I just throw up my hands and say "forget it! It's good enough". I photographed my grandson playing baseball this spring, and honestly got better results "eyes in focus" with my OM-1.

Curious to read more about the A6700, I hope it will be a substantial upgrade.

I tried the A7Rv for wildlife photography when it first came out and concluded it nowhere near the A1 particularly for birds in flight - so I ended up buying a second A1 as I wanted two bodies for African safari. I know the A1 is expensive, but for wildlife it is still the best, by far.

I have the a7rv and your experiences with its autofocus matches what I have found. For people the ai autofocus is a definite upgrade and can easily be seen. For animals and birds in flight particularly, the ai focus is much less convincing. I also have an a1 and I do think in part the a7rv is a bit restrained by the slow sensor which doesn't show up with people moving around but does with fast moving subjects such as birds flying. Side by side the a1 is quicker to acquire and will hang onto subjects af wise much longer than the Rv. Also I was expecting the Rv to recognise birds and animals easier than it does and again it doesn't appear any better than the a1 (maybe less so in fact). The menu system for the af is unnecessarily complicated and suggests to me Sony knows they may have not got the system right yet. Why else give so many options if you were confident about the af capability. Hopefully because it has a separate ai autofocus chip then Sony can improve its recognition capabilities in these areas. After all it's a first generation idea on this camera and in every other respect the camera is superb.

I spent a lot of time trying to troubleshoot BIF focusing issues (or to be honest almost absence of AI AF) on a6700 with different range of the lenses and camera settings. Unfortunately it looks like ALL new Sony AI based cameras suffer from the same issue - they cannot detect and properly track fast objects especially if these objects change their form (like bird moving wings during the flight) or "run" from one side of frame to other. Statical (on a tree) or slow moving birds and animals can be detected and tracked on average or average+ level (I would say previous non-AI animal eye autofocus on a6600 worked better!). It is strange but other brands do not have such problems with AI chips / software. For example, in similar conditions (same place, same light and the same flying birds) my Olympus can detect and follow BIF without any hesitation... but bokeh in comparison with Sony is another story...

For lenses, if shooting 30fps is not important and 15fps is while keeping weights down during the wedding day is more important than the 3rd party Tamron 35-150mm f/2-f/2.8 zoom lens should provide you 35-215mm f/2-f/2.8 between FF 50MP & APS-C 21MP mode without the need of carrying a bunch of primes & zoom lenses and missing moments when swapping out lenses. Not to mention less frequent sensor cleaning would be required due to having one lens living on the body 99% of the time. I know most of us are all brain washed with "Trinity" lenses but my 16-28mm f/2.8 sigma now lives in the bag 99% of the time as I have learned to live with the 35-150mm. FF 35mm f/2 = APS-C 50mm f/2... 2 primes in one high MP sensor. Not bad for close up with 50MP either without carrying a macro lens.

Same experience after serious testing inna all Sony system. That the AF system has the posssibility of a working setting somewhere in the menu, is not worth the effort in my opinion. Chances are the camera is in a different setting and the shot will be missed. It took a sitting - yes sitting - peacock to reach 30% succesrate. After changing the setting within 'bird', the peacock was gone. This implementation of AI needs some serious technical and user friendlyness firmware update(s) in to even come close to the hype, in my opinion.

Yes for the lens, and it's an old firmware actually: it came out in November '22 and is about the stabilisation, not the AF. Firmware 2.0 for the A7R V came out after my test, but again it's not about the AF, but the new Creator app (at least according to the official release).

Let's see... The same ratio obtained with less expensive cameras like XT4, XH2 and XH2s.

I think my A7RIII with the small spot AF box works much better than the A7RV for animals and birds after using the A7RV myself. The supposed AI AF is more of a hindrance to wildlife photography than anything else and past medium range, it's completely useless. The human eye detect might be impressive but haven't tried that personally as yet

So in conclusion _ don’t sell your A1 :). I guess Sony wasn’t stupid enough to make a camera that was superior to the higher priced model.

Not sure how you can say for the A7IV: if bird is covered by a object the camera detects greatly the bird. That’s simply not true: if an object is in front of the bird, the AF detects the object closest to the camera.

We have different experience then. See answer above.

I can confirm that my a7iv focuses at the birds eye even with branches in the fore and background. This happened after upgrading both firmwares of my 200-600 and a7iv (version before the creator app). Depending on the available light it sometimes struggles but I noticed it less than before I updated my firmware. On a different note, it’s disappointing to hear that the newer a7v bird af performance is not as good as the a7iv, but I guess that’s a blessing in disguise as I will instead focus in spending to find them birds than getting a new body. Thanks Matt for the great review! 🥂

I find it horribly confusing with regards to Sony's cameras as to which is best for wildlife and macro. You speak to Sony and they point at this camera. However its clear that its not up there with the A9 / A1 in fact according your list its down the bottom of the list...

Keep in mind that my list is specific to AF and birds in flight, it’s not a rank about the cameras as a whole. But I understand what you are saying, the A7R V would not be my first choice for wildlife. It would also help if Sony could be more consistent with firmware updates. For example they added focus bracketing to the A7R V, which is great for macro, why not add it to other cameras via firmware…?

Canon R7 has better bird eye focus than the A7RV for only $1,399.00 - i have both bodies. I will be returning my SonyA75 to get a full refund ... very disappointed with the gimmick "ai" chip.

User error? Or perhaps system related issues? Not sure if it is possible to trust your statements. If you would say, in my opinion, basing on my short experience, during my a few shooting sessions, etc than perhaps we could learn something from you. But if you are just saying A is better than B then I’m calling it BS. There is no perfect camera…
