Hi everyone. I have some lenses and wanted to see how the image quality compares between the lenses. So I set up a "scene" (not a lab test) in my yard and used a tripod to shoot each lens at different focal lengths and apertures since there doesn't seem to be any comparisons for these older lenses to new lenses and my 80-200 HS is amazing but I wanted to see how it compares. Now I have a ton of images sorted in folders. Unfortunately I don't have a lot of time to do a detailed comparison. If anyone is interesting in doing some comparisons and sharing with the community then I am happy to share the images.

Here are the basics -
Body 1 - Sony A99ii (LOVE this camera!)
Body 2 - Sony A7Rii (same sensor)
Adapter 1 - LA-EA3
Adapter 2 - LA-EA4
Adapter 3 - Tamron-F 2X Mx-AF BBAR MC7
Lens 1 - Minolta A 80-200mm f2.8 High Speed (LOVE this lens!)
Lens 2 - Minolta/Sony A 70-200mm f2.8 SSM
Lens 3 - Minolta A 300mm f2.8 High Speed (Beautiful lens but I don't like the bokeh)
Lens 4 - Minolta A 28-70mm f2.8 G (pretty disappointed in this lens)
Lens 5 - Tamron FE 17-28mm f2.8 Di III RXD (sharp but dead)
Lens 6 - Sony FE 85mm f1.8 (also sharp but dead)

I had to return the Minolta/Sony 70-200mm f2.8 SSM because the zoom ring was really sticky so I don't have it anymore. Otherwise it was pretty nice. Also I used the money to help buy the Sigma 120-300mm f2.8 DG OS Sport. So far IQ looks really good but AF with the MC-11 on the A7R2 is really poor. I should receive the dock and cable soon to check the firmware and adjust if needed.

Just to note that my test scene was set up to replicate how I like to shoot - into the sun at noon with the out of frame and camera and lens in full shade (umbrella).

Let me know if you are interested.
