    Posted: 08 July 2020 at 10:39
Hello,
May be someone use this combo?
Now I use a77ii with SAL70400G2 for birding. My camera approached to 100000 clicks and sooner or later I'll need a replacement.
I'd prefer to get a6600, but it's very important for me to be able to use this lens (I can't afford 100-400).
So I don't know what to do - to buy another a77ii or a6600 with la-ea3.
I want to hear your opinion about autofocus tracking with this combo.
Thank you.

Are you happy with your A77m2? Getting another one is the cheapest option. You could even add an A6100 for general photography!

If you go A6600, do you really need 400mm or is 350mm long enough? If so, the 70-350G would be an option.

People have used the 70-400G/G2 with the LA-EA3 on lesser cameras with success. But a native lens is much better. Also, the 70-400G/G2 is quite unwieldy on the small A6x00 bodies.

I have experience of the G1 lens on the A6300 and more recent experience with a native lens. The G1 was not too bad; it was not in the same league as the native lens when it came to nailing and speed of focus.

I think Addy is correct.

This was important to me too when moving from A99/A77 to A7iii last year, and I bought the la-ea3 specifically for use with the 70-400ii. I took it out to a local bird park, aptly named Bird World and was very impressed with the AF performance. I'm not sure how the A6600 compares to the A7iii, but certainly I got more keepers with the A7iii and LA-EA3 than I ever did with the A77 or A99. I've been blown away by the A7, and while it's not cheap to migrate to E mount, the LA-EA3 helps take some of the pain out as you transition.

Here's a couple of examples:
400mm


400mm


250mm

1. I'm happy with a77II, but I want an improvement in AF performance for general photography (kids) and in high iso handling. A6100 is not an option - I want to get Tamron 70-180 and I need in body IS.
2. I have 70-300G for A mount and was never completely satisfied with sharpness. Also, why should I invest to get inferior lens?
3. This is my question, how does it perform in comparison with A77II? And yes, it looks and fills strange on the small body, but so would be 100-400.

G2 has a much higher AF speed than G1, so it's not a fair comparison.

I'm glad to hear about your experience. Also, very nice shots

A77II has a much better AF than the original version, so it's not a fair comparison.
I don't want to go FF because of the reach of telephoto lenses. A7RIV is beyond my budget.

Thank you all for your quick replies. I tend to go for a6600 variant in spite of the weirdness of the setup. May be Sony will release APC camera in FF body...

I'm recently getting into birding. I'm a bit invested into the A-mount so I haven't yet checked out the E-mount options yet. If money was no issue, the 200-600 is perhaps the best best, from what I've seen.
I know you aren't looking to splurge so I'd have thought a used A77Mk2 in good condition with a low shutter count would've been a good option for you.

Also the 70-400G2 is quite well regarded so I'd have thought the A77Mk2 along with the 70-400G2 would quite suffice for most hobbyists.
How do you find the performance of this combo? What's your hit rate and keeper rate? I'm definitely interested in your experience with it.

And, welcome to Dyxum!

Sony only allows 2.5 or 3 FPS AF-C in bursts with A-mount lenses on non-A9 cameras even with SSM II lenses (i.e., the LO frame rate option.) The SSM II zooms have the same motors as the originals. The AF tracking ability was increased up to 4x according to Sony. The LA-EA adapters don't seem to have any support of those SSM II improvements except the LA-EA3 on the A9 models where the earlier lenses support 8 FPS AF-C tracking during bursts and the II's support 10 FPS.

The A6600 is a lower-end camera than the original A77, not the mini A9 some have been hoping for. It did get the bigger battery and a thicker grip. There's no support for any of the post A77 A-mount features in the A6600: no Lens Compensation for any A-mount lens--meanwhile the original A7 has the same Lens Compensation support for A-mount lenses as all the post A77 A-mount bodies. You do get the new AF tracking system using the LA-EA1/LA-EA3 with the A6100, A6400, and A6600 with the LO frame rate limitation.

Cheaper than GM zoom options for E-mount cameras are the Sigma 100-400mm F5-6.3 zooms, either the new native one or adapting the EF or SA version with their MC-11 adapters. These both should allow 11 FPS AF-C on the A6x00 bodies. Though Sigma doesn't claim any AF-C support with the MC-11.

Another option for >3 FPS AF-C is adapting EF lenses with the Metabones IV and V adapters using their native Advanced mode. This mode limits phase-detect to only a small central region, since Metabones does not do the work Sigma did with their Global Vision lenses with the MC-11 to get phase-detect working across the frame (and Lens Compensation).

The 70-400G SSM I tried wasn't even as sharp as the Minolta 100-400 APOs I've had, but maybe it was an outlier. These internal focus x-400mm zooms lose focal length with close focus, and even a fixed 400 mm prime is not much tighter than a true 300 mm lens.

It really depends on your technique and object. Single shot AF is brilliant. Tracking birds in a blue sky is easy, but when it gets to a busy background it often loses the target, but when it works, it works well. In general, I don't feel that AF speed or precision is insufficient (yesterday I managed to get some swifts (like 10% keeper rate, and not because of AF speed).
The real issue is ISO noise. For birding i use shutter speed 1/1600 and with the aperture 5.6 it quickly gets to 1600 (I shoot manual with auto ISO). 1600 is still usable, but not 3200. Also, 400 mm feels to me somewhat short (but it's like 600 mm in FF).
200-600 for me is too restricting on the short end.
   
There is no free lunch/

And I'm not exactly new . I'm a passive user from 2006, since I've got Minolta 7D.

If it's so, it's a deal breaker for me.

But I've heard that firmware update have solved this issue. Can anyone confirm?

There's been no firmware updates to the A6600.

The LA-EA3 required a firmware update to support 8 and 10 FPS on the original A9. There's been no updates since then. Only an updated LA-EA3 with the fully electronic shutter of the A9 models support AF-C in bursts beyond the LO frame rate.

My fully updated A7III only tracks focus in bursts with my updated LA-EA3 and SSM II lenses at the LO frame rate both with mechanical and fully electronic shutter.

It is not true. Just tried my A6400 with LA-EA3 and 70-400G and it did 8 frames between [1:28.25] and [1:29.25] at the HI setting. That is the advertised 8fps.

The 70-350G is sharper then my 70-400G - it might look like a lesser lens, but it punches above its weight.
