    Posted: 17 May 2024 at 16:47
Hey all, so its been an interesting time, I've REALLY gone off the deep end getting back into photography and having a lot of fun. I took another plunge and decided to sell the a99 and a7ii I only recently bought and spent not a small amount more to get low shutter count copies of an a99ii and a7rIV. I could give you a list of reasons for each, if you want, but I'll spare that for now.

My biggest concern was having solid support for my collection of A-mount lenses. I have really no desire to replace them, I like the characteristics of the old lenses and am only lacking a couple Minolta AF lenses that I'd say I really want at this point. So having really good autofocus is important to me. The features on both bodies seemed right to me so I wanted to compare how they perform. I wanted the higher res "r" sensor because I like buying storage space more often and filling up memory cards in seconds ;) Now there are tons of differences in these cameras, but the most interesting comparison to me was the autofocus.

None of this is objective, just me comparing around the house and in one real world scenario where I actually do photography which I'll get to. Most of the time I use flexible spot AF. I have the LA-EA4, the LA-EA4 Monster (I did the mod myself following one of Gary Friedmans videos, not too hard) and the LA-EA5 so I tried to compare all 3 against the a99ii. Around the house I was just aiming at various things at different distances and seeing how fast I could get focus. The lenses I tested the most with were Minolta 80-200/2.8 and Minolta 100/2 since I use these a lot. I experimented with lighting by turning lots of lights on and also just having one dim light, which basically means both cameras were working at the limits of their autofocus capability. The LA-EA5 seems the most obvious choice since it uses the bodies sensors, doesn't need the SLT mirror and its not a 3rd party item but I was still curious how the other two would compare.

Generally speaking the a99ii wins, but its really only obvious on dimly lit subjects which really challenge the camera to get focus. If there's good lighting the difference between the EA5+A7rIV and the a99ii was negligible in my opinion.

The original LA-EA4 performs nearly identically to the a99ii but there's the obvious limitation that it has far fewer focus points and you lose the advantage of not having the SLT mirror. Interestingly the Monster adapter is faster than the EA5 in some cases particularly with darker lighting. However, the fatal flaw with the Monster is that it randomly flips out and I have to turn the camera off and back on, or detach and reattach it. For me that means its 100% not useful in the real world, such an incident would invariably happen right at the exact moment causing me to miss "the shot". I would also point out that I tried the Monster on the a7ii (the original reason I bought the Monster) the a7rIV performs much faster with the Monster. This makes sense given that the adapter allows the use of the cameras native autofocus.

Anyhow the most interesting test is the EA5 vs the a99ii and in this case the performance is close but there are times the EA5 just can't keep up in my around-the-house testing.

So who cares how the cameras perform in a scenario I would never be doing? I also was curious how the two compare (that is A7rIV+EA5 vs a99ii) in a real scenario for me. I do a lot of photography for my church and typically during the worship service we have dim room lighting with just lights up on stage and background lights. In this scenario, I didn't notice even once that the EA5 wasn't getting focus fast enough for me, both cameras perform well enough and I could use either one for this type of shooting without worry that I will miss a shot. For a little additional insight, the original a99 did struggle a lot in this environment, and the a99ii was a clear upgrade.

Again this is my very non-scientific comparison and at the end of the day what matters to me is whether the cameras do the job in the scenarios I like to shoot in and that they are comfortable and intuitive to use. I don't think you'd want to do sports photography with the EA5, just pick up a native lens or stick with an a-mount body if that's your use case. But for my interests, both setups are great options. In one sense I can now recognize I no longer "need" an a-mount body, finally, but at the same time I don't want to give up a-mount bodies. The a99ii is an excellent camera to me and a great backup to the a7rIV.

I may start doing some professional stuff again and these two would be great IMO, for now I am just enjoying the hobby once again. I just thought I would share in case anyone else just crawled out of a cave like I did and is just getting up to speed on what's happened with Sony in the last 10+ years!

Thank you for this comparison. At least you understand that your A7riv will always perform best with native glass. I don't have the monster adapter but do have the LA-EA3 and LA-EA4 and they both perform fine with the A mount lenses I have. Mostly I use my SSM lenses with the LA-EA3. But I don't use them often. The balance and weight is not comfortable for me.
Still have my A99 which sadly doesn't get much use. Mostly I use my A7rIIIa, which is 42Mp like your A99II. I miss the articulating screen of my A99 and the built in GPS. Down the road I probably upgrade to the A7rV if the price drops a bit more. Coming from Minolta AF and MF film cameras it is truly amazing how far Sony has come with the technology and performance of their cameras and lenses!

I too have the A99ii & A7Riv/LA-EA5 and I find the difference is not so much in AF speed as in AF flexibility where the A7Riv has more modes/options and accuracy without fiddly microfocus adjustment. The other issues that would, I have thought, swing the decision towards the A7Riv in the church scenario described is it's improved higher ISO performance and silent shooting mode (though screwdrive is never silent).

That said the A99ii is still a great camera, I'm not about to part with mine.

With both cameras I compensate for lack of GPS by linking to my phone - but do at times miss the articulating screen of the A99ii when using the A7Riv.

With both I miss the IISO hot shoe, the flimsy contacts on the multi-shoe are absurd.

Phil,

That's right about the connectivity with the phone for Geo tagging, and it works most of the -- time until it doesn't! Or I forget and leave my phone in the car, or the battery dies etc. Anyway it's not foolproof. But its really a minor nit! I miss the articulating screen when I try to shoot low to the ground in portrait orientation. Most of the time tilt is Ok. Flip out to the side and tilt works of course, but I don't like it (A7iv).

I agree with the Af flexibility on my A7III and A7rIIIa. I feel like I have much better control over my focus points than with my A99, but of course I have no idea about the A99II. But absolutely all of these cameras are capable of capturing great photos.

You are right about the multi-interface shoe, but honestly I don't use it much. I don't shoot video so I haven't needed it for microphones.

I think the screen articulation on α7R V and α9 III offers the best possible flexibility: tilts like most older α7 series models AND rotates into side.

IIRC α99 II had more AF points than earlier A mount models, but still the coverage is inferior compared to E mount cameras, which can focus pretty much anywhere. And the newer models then have all these eye detection and focus tracking features, which are not found on any A mount cameras.

suggestion DO NOT use the EA4r Monster Adapter with the a7ii or old cameras with the small battery, it could short out https://www.monsteradapter.com/blogs/%E6%96%B0%E9%97%BB/la-ea4r-important-notice-do-not-hot-swap-a-mount-lenses-while-camera-still-on

I tried it and had the "randomly flips out" problem with my a7ii like you have, then I found out it was a "known issue". The EA4r Monster seems "better", but especially the AF500/8 (Gary Friedman has a couple videos) because the Monster uses all the focus points.

amen!

You recall incorrectly. With Sony lenses the A99m2 has the same number of AF-points and coverage as the A7r2 (and A7r3) with some cross points that neither the A7m3 or A7r3 have. The A99m2 also has eye detection AF and has focus tracking features.

The A99m2 is an impressive camera that doesn't get the respect it deserves.
