    Posted: 14 May 2019 at 22:49
I am considering moving up to the A99ii but wondering how my older lenses will do on 42mp camera. For instance, the Minolta 28-70, 2.8, Tokina 100-300 f4, Minolta 50 f1.4. Any experience with these lenses on the a99ii.

Thanks, Jack

As long as you use full frame lenses, you will get the same or better results. Both the A99 and A99II have sensors that measure approximately 36 X 24 mm. The newer camera merely gives you more pixels. The A99 gives a 6000 X 4000 pixel image while version II gives 7952 X 5304. I am no optical engineer but hope this helps.

Moving up from what? Actually, that doesn't even matter. It's been shown numerous times that increasing sensor resolution or increasing lens resolution brings benefits to the final image because the two factors are complementary. That's what you can expect.

Thank you for the quick response. That's what I thought but never hurts to ask, there are always unknowns.

Thanks for the prompt response. Moving up from an a99. Pretty much what I thought but there always surprises. Never hurts to ask. Cheers, Jack

If you're a pixelpeeper you will see the aberrations of the lens better. But if you downsize to the 24mp of your A99, the results will look better.

You will also have a better AF system in a slightly smaller body.

They will work with some caveats.

First, as with any other lenses they will be limiting the sensor resolution in some degree, but you will notice an improvement when compared with photos taken with the a99.
I have noticed an increase in sharpness with the 28-70G, after tweaking with micro focus adjustment. I never noticed this on the A900.

Second, hybrid af won't work and you will have limited af focusing points available.

On the plus side, eye-af works perfectly with these lenses. It's wonderful to do portraits with Minolta 85mm f/1.4 original.

Does it means they are not good? Certainly not, actually I kind of continue to prefer the rendering of the Minolta lenses to the sony/zeiss.
Unless you are always seeing your photos at 100% (I do for checking focus only), or you like clinical perfect lens, they will give you greath results.

I am sure the Sony/Minolta 50/1.4 out resolves 24mp by a fair margin at f/10, so, I expect it will not limit the sensor of the A99m2. Did no formal testing, but having used the combination, I never felt the 50/1.4 was lacking on the A99m2.

The Minolta 28-70/2.8G in my experience always benefitted from some extra sharpening/micro contrast, also on the A900. The resolution is there (maybe stop down to f/4) but it lacks micro contrast. To be fair, I usually use the Sony/Zeiss 24-70/2.8 on my A99m2.

I find btw that my beloved 17-35/3.5G is struggling on the A99m2.

Oh,and yes, you do not have hybrid AF, but the normal AF system is very capable and the only caveat is that it is a aps-c system, so it is quite central.

If you ever take jpegs in camera you should notice heavy cropping is noticeably improved, and high-ISO noise too.

In my experience the 50/1.4s vary quite a bit. My beat up 1985 Minolta is sharpest one I have, but the Sony gains ADI, 5-axis stabilization, hybrid AF, and Lens Compensation. I would look for a sharp Sony if I had an A99II.

Thanks for the advice. I'll see how my minolta works and go for there. Isn't the stabilization in the body? I was under the impression that with the 99ii stabilization was always available regardless of the lens. Is that incorrect?

Thanks, Jack
