Legacy Lens Capability
This was one of the biggest selling points of the Sony line to myself. You see, that Sigma 300 mm F/2.8 lens set me back a few bucks and it wasn’t the dollars down the river I was concerned about, it was sending more down the river to replace the lens. I recently read some photography columnists and writers say just get new lenses. Well, I can not justify that extra expense and when one sees the format difference between 35 mm and APS-C multiplies the focal length by 1.5x and doesn’t cost you any speed, what is the problem?
So far, my old Minolta lenses work fine with the Sony A55. They focus quick and expose properly. However, I do have one lens that got a little beat up and the autofocus does not work (you can hear the mechanics working but the linkage between the AF motor and the lens focusing mechanism is broken) and I suspect manual exposure settings on that lens are also broke. I could get good auto-exposed manually focused shots, but when I attempted to set the exposure in full manual all of my shots turned out severely under-exposed. Yes, I did set the manual exposure to what the camera was doing in A, S, and automatic modes. I will have to check out how my other lenses manually expose.
My 2x tele-converter similarly works fine. It communicated just fine between the camera and lens and I was able to auto-focus fine with it.
