I'm not familiar with the Seikanon brand, but assume it's similar to many other lenses of moderate price and quality. Designing and making a fine zoom lens requires care and expertise. Prices reflect this. Inexpensive zooms may, at best, have inconsistant quality. One may suit you well for small snapshots. It depends on how critical you are. Don't expect it to deliver larger images that compete with the leading brands.
okay. Its for old Minolta manual focus cameras. most of the better zooms like tamron for this camera are pretty cheap also so It's hard to tell whether this one is good or not. I might give it a try because it probably only will sell for 20-30 $
are the Adaptall II mounts the same on the AF and older MF lenses. what I mean is could Ibuy an AF adaptall II lens and buy the mount for the old minolta MD manual focus cameras. Iobviusly would have to use the lens in MF mode and the program features wouldn't work but could it be done?
With the converters you will have a 200, 280 and 400. Secondly, no you can't get a minolta AF adaptall mount as there is no such thing... Minolta's AF and MF mounts are entirely different. Only Pentax and Nikon users can mount MF lenses on AF bodies using the adaptall system.
If the better lens doesn't cost much more, buy it instead. I've got an old Samyang 35-135 for the Minolta MD mount and it is okay at F8~F22 but otherwise pretty soft. I replaced it with a Sigma 28-200 which is much better and still in use.
