    Eye AF test

    Actually, my A6500 doesn't support Eye-AF when wearing a Canon EF 85mm f/1.8 lens adapted with a Sigma MC-11 adapter. However, since I updated the MC-11 firmware, Face Detect AF is supported. The Face Detect AF seems to do an efficient job focusing on the eyes, even in close ups of faces when you might think that the camera would focus on the nose since the nose is closer to the camera than the eyes...

    I would not normally use f/1.8 so close to the subject's face. I would either back off a bit or use a more reasonable aperture like f/4 or f/5.6 but, this was a test to see how well the Face Detect would focus on the eyes...

    I am really going to put this lens along with my 50mm f/1.8 Sony f/1.8 OSS lens through their paces at a Renaissance Faire on Saturday or Sunday...

    Richard I'd be interested to see what you find with the 50mm f/1.8. Do you have the E or the FE?

    I'm thinking of getting the E 50mm for use on portraits with my a6000.

    Dave, I have the E or Cropped Sensor version, or the Sony 50mm f/1.8 OSS lens. I have no experience with the FE or full frame version but, from my research, I suspect that the crop sensor model produces slightly better image quality than the full frame or FE version. I think that the image quality of my lens is just fine and the Eye-AF is amazing. The crop sensor lens has OSS which should help with your A6000 since that camera doesn't have IBIS. The wide open f/1.8 aperture really blurs the background.. I purchased the lens used at less than $200 USD...

    Here are some images that I shot wide open with my A6500 and the OSS lens...

    The EYE AF really nailed the focus on the subjects eyes. It is fun to use and so easy that it seems like cheating. (but, that's what I thought when I first used autofocus lenses). No focus and recompose needed. I have experimented placing the subjects eyes in any part of the frame and Eye AF consistently nails the focus.
    For these shots, I used aperture priority, continuous focus, wide focus area, and Eye-AF which I set up for the AEL Button. I first tried using the rear center button for Eye AF but, that button was not convenient so I switched the Eye AF to the AEL button which is closer to the shutter release button.
    My next shot will include fill flash with a Godox tt865S on a bracket and Godox Pro trigger...

    Thanks Richard, excellent quality there and yes the focus is spot on the eyes. I'm using the AEL button for Eye AF also, it is in a good position because, as far as I can tell, you have to keep that depressed until after you've pressed the shutter. Thumb on AEL and index finger for the shutter button!

    Actually I just bought a E 50mm f/1.8 OSS today. So far I'm very impressed. I haven't shot with f/1.8 yet but have with f/2.8. It is nice and sharp and you can get good separation from background.

    Re: Eye AF test

    I like to shoot with a pair of cameras and my Canon DSLR cameras and lenses have been gaining weight as I grow older

    The Sony A6500 is a great compromise between the heavy Canon DSLR gear and smaller format equipment.

    I thought that I could use my stable of Canon glass with the A6500 and the MC-11 adapter, which I got with the camera when I purchased the A6500 used... Some Canon lenses work quite well but, they don't generally provide the AF capability of native Sony lenses.

    I was surprised at the capability of the Sony 50mm f/1.8 OSS lens for portraits ad I am very happy with that lens.

    I "think" that I can "make do" with the Canon 85mm f/1.8 adapted to the A6500 with the MC-11 adapter since the native 50mm does such a nice job on portraits and I get "reasonably good" AF with the adapted lens. I recently saw a used copy of the Sony 85mm f/1.8 go for $425 (USD) on my local craigslist.com. Unfortunately I did not have the ready cash to pick up this bargain. But, it <AY have not been in excellent shape like the seller described

    Speaking only from a focal length and aperture point of view, I suspect that the Sigma Art 50-100mm f/1.8 lens would be a great portrait lens for a crop sensor camera. However, the darn thing is so heavy that it would negate the light weight of he A6500 body... I have to keep aware that the main reason for using the A6500 is to reduce the weight of my kit. I could easily build up another kit too heavy to carry if I am not careful. My present three lens Sony kit with a flash, filters, strap ad its case weighs in at about 1.5-2.0 kilograms which is certainly a change from a full frame Canon kit!

    I just found out that the Sigma 30mm f/1.4 Contemporary lens supports the various A6500 focusing methods including Eye AF.
