I think I need an AF tele, manual focus has it's limitations, especially when traveling. I am trying to chose between Minolta 70-210/4 "Beercan" and SEL55-210. Assuming optically Beercan is the same as it's older MF brother, here's how they seem to compare: Price - Beercan is about $90-110 on eBay, SEL is about double that used, from what I could see. IQ - While SEL can produce some very nice photos, if Beercan is the same as my MD70-210/4, it should have superior optics. AF - this one I don't know much about, supposedly neither is a speed demon on Ne Tele end - Beercan is faster and supposedly better IQ wide open at 200mm. SEL has OSS. Don't know how they stack up. Low light - again, Beercan is constant f4 while SEL has OSS but much slower apertures. Is f4 unstabilized going to win over stabilized f6.3 ? Which lens is slower focusing in low light ? Size - SEL is more compact, plus I assume it doesn't eat up the batteries the way LA-EA2 does. So, which one should I go with ? Anyone has both to compare ?
