I have a question.

I've bought various M42 to Sony Alpha adapters, with and without chip, thin and thick. All have common problem. I only can get infinity focus (and even focus past infinity), only with soviet lenses (helioses, jupiters, mirs, etc). With all chinons, yashicas, vivitars or whatsoever for M42, I get infinity at about 3-4 meters on 28mm and wider lens, about 10-12 meters with 50mm lens and say 40-50 meters with 135mm lens. Why so?


Are you or are you not reaching (or going past) infinity on all lenses?

I don't know about Dyxum's ratings, all I know is what my eyes tell me about the lenses I've owned and used.

The 1985 Minolta 'beercan' 4/70-210 is a better lens, overall than the current Canon EF L 4/80-200.


There isn't a current Canon 80-200/4, do you mean the 70-200/4? If so, the Canon feels better built to me. Plus the Minolta suffers horrible purple fringing. It was the biggest Mintola AF let down for me after all the hype (I tried two). Was very good for portraits though, and I do get what people mean when talk about Minolta colours Smile

Yeah 4/70-200; a friend has one an I've played with it, a good lens but I was surprised it wasn't better than a good old equivalent like the Viv Series 1 3.5/70-210 or Tokina 4/80-200, contrastier in tricky lighting but often less sharp - auto focus accuracy perhaps?

I've never had particularly noticeable purple fringing with my beercan, copy variation maybe?

This comparison shows the old Minolta can easily match the Canon:

Thanks Ian! Great article, never seen that website before!

I must say: i did not ever own any of those. I did move from Sony to Canon because the 5D was the first full-frame DSLR that came within my budget. I did however own the plastic Minolta 70-210 and once i had a 75-300, i sold them both quickly, they were very dissapointing to me back then.
Maybe because i compared them against a Sigma 75-200 2.8-3.5, which i still have, a metal built and heavy lens, but a very good performer! Funny fact: it does not get a very high rating on Dyxum, however that could be because of the push-pull and the fact that some examples don't seem to work on all Sony cameras.

Photoclub Alpha is a really good site, their reviews are great.

I've been looking for that 75-200 Sigma for months, but it's really hard to find, only ones I've seen have been in the Olympus and Yashica AF mounts, which were hardly popular or long-lived systems. Sad

must have been the Minolta AF 70-210/4.5-5.6.. this really isn't a very good lens.

However another plastic lens (but metal mount at least).. the Minolta AF 70-210/3.5-4.5 isn't bad, to be true I liked it even more than the beercan. This could be a good and cheap option.

Oh and don't forget the Minolta AF 100-200/4.5 (mini beercan).. this tiny zoom is really impressive. Just stay away from the Minolta AF 80-200/4.5-5.6.. one of the worst Minolta AF I ever tried!

Yep the 100-200 is really good, and in my opinion better than the 70-210, I use that lens trackside for Bike and car racing, as it will push through fences, and the autofocus is dementedly quick. has no problem being used for track days, it is light and well built
