That's not good news on the Vivitar. I guess you get what you pay for. Does anyone know of any tests for the AF version of the lens?

I also just scored on this auction: http://cgi.ebay.com/ws/eBayISAPI.dll...tem=7603974531. It's almost lost in there that the Minolta film SLR comes with a Tamron70-300 4.5-5.6 AF lens. While that is not very fast what a deal for an almost new 35mm SLR withazoomlens for $26!!!

Since I am going to have three telezooms now (my Sigma 75-300 4.5-5.6, the Vivitar 70-210 2.8-4, and the Tamron 70-300 4.5-5.6) I am going to do a lot of tests and keep you guys posted on my findings and then I might sell off what I don't need.
Sounds like you made out fine on eBay. Go to the link I provided for Pop Phot and you can find all their lens reviews.

Yeah, man I scored on that ebay deal, and the good thing is the lenses for my 5D are all interchangeable with the Minolta 3000 (unless they are digital only).

I checked your link but I cannot find a review on either of my lenses there. In fact I cannot find a review anywhere on the net for the Vivitar 70-210 2.8-4 AF lens....

The Vivitar lense is made by Cosina, a japanese lense maker. It is also sold under the names Soligor, Voigtlaender and Cosinas own name. Usually the Cosina lenses have a poor reputation, but this one seems to be a better one. The MTF results cited by Jim are not the bad if you compare them with similar lenses on the same web site. Especially you should look at the MTF tests when stopped down. Lenses which have an overextended focal length or aperture range score badly in these tests, because the bad focal length/aperture combinations have the same weight. Also these MTF tests have to be done at a rather close distance. That's why macro lenses score so extraordinarily well in this test. At more normal distances the differences between the various lenses are much smaller. That's why the user surveys in http://www.photographyreview.com/ and similar sites show much better results.

Danke sehr, Rainer. You've made me feel better. Will let you know results of my comparisons. Nice house you got, by the way.

The reviews seem to be quite mixed on the Vivitar: http://www.photographyreview.com/cat...0_3128crx.aspx. Two 5-star reviews, and one 1-star? How could the same lens be so different to some users?

I wasn't sure if they had reviewd it or not. BTW, I checked eBay with a reputable dealer who I have bought quite a bit from, and his price on the 3000 alone is nearly double what you paid for the whole thing.

i'm thinking of getting an older maxxum as a back up for when i go on cruise (its a 60 day stint with stops in europe). there are quite a few with tripods, and large cases which i can use with my 5D and overall all the prices dont exceet $100 for the 7000. im thinking the maxxum 7000 will work with this older (1989) sigma 75-200 and AF with it, and which other models would work with this?

I frankly don't know much about Minolta film SLR's. I figure the 3000i I just won on ebay was their entry level model , since they also had a 5000 and 7000. But it's like new and comes with the 70-300 lens. Darn what a deal. But I am not sure which lens works with what, DorkUnderwater. By the way, since soon I will have three telezoom lenses that work on the 5D, I'll sell you one of them for a good price if you are interested.

That's good way to get lenses on Ebay. I got a Maxxum 7000 with a cherry Minolta 50 F1.7 for $36 about a month ago. Also got a Maxxum 3Xi with a Minolta 70-210 F4 and Minolta 35-70 F3.5-4.5 for $90. Some times people overlook these as they are focused on the lens(no pun) and don't look closely. It can be addictive(lens lust) but you never know what you may find. Good luck rduve
