An updated beercan: Maxxum AF Zoom 70-210 1:3.5(22)-4.5

Cost: $25 (average cost: $30)

As the successor of the famed "beercan" Minolta Maxxum AF Zoom 70-210 F4, it came with high expectations. Not only is it a little faster with a variable aperture (half a stop in the wide range), it's a heck of a lot smaller and lighter then the original "beercan". But if that comes at the cost of image quality, is it really progress?

Without having tested the original beercan, I can't really say that is the case. I was actually pretty pleased with this lens. Light, easy to use, fast focus across the range, and decent image quality. It's sharp across the image, and across the full range. It has rich colors, and I did not notice any significant colors aberration beyond what you would expect from an older lens, aside from some purple when pointing in the direction of the light. It is strongly recommended though to use the included hood, in order to avoid flares.

Aside from the good performance, I also liked the look of the lens. Not as solid as other older Minolta Maxxum AF lenses, but it still oozed quality with it's looks, while looking nimble for the range, and the fact it's an auto focus lens. Compare that to the beast of modern zoom lenses.

The "hold" button is use to hold focus or DOF, but only works with compatible camera's and my Sony is not.

As a warning, I did hear that not all copies of this lens performed as good, but if you can find a good copy, as I did, you might be very lucky.

Does weight predict quality? Maxxum AF Zoom 28-135mm 1:4 (22) - 4.5

Cost: $25 (average cost: $50, to over $500 if in perfect condition)

I expected much more of this lens after the glowing reviews by Ken Rockwell or Kurt Munger, but I can't really say it followed the expectation. In all fairness, my copy had a dent at the front, so maybe it did have some internal damage. But autofocus was still working.

This lens was one of the first Minolta auto-focus zoom lenses with the AF mount. Being almost all metal, it feels very solid. But in practice, it also makes it very heavy to use. I had it on a small tripod for a moment, and it just kept falling over.

The lens is also know as the "secret handshake" lens, with the idea that it was the result of a secret partnership between Minolta and Leica and sold by Minolta at a lower cost to say thanks to their customers. There is however no proof of this, and pretty unlikely to be true. The rumor is persistent though and refuses to go away.

For looks, it aligns with most other Maxxum AF lenses. The range is very nice from wide to a reasonable zoom. Perfect for a nice nature walk, but who want to carry such a heavy lens with him. The lens has a Macro setting (losing the auto-focus capability), and although it did work, I was not able to take one Macro picture I was pleased with.

For the rest of the image quality, I found the lens to be very soft (to soft) when wide open, creating a soft glow. It's sharper when dropping a few stops, but I still found the pictures dull and not as sharp as other reviewers were raving about. also be very careful for the sun, as the flares are heavy in this one. It is weird that it was never sold with a hood, as a hood is strongly recommended to control flares.

Can it take good pictures? Yes, but in most cases I was wondering how much nicer the picture would have been with a better lens.

Again, it might be just my copy of this lens. As a Minolta collector, you need to have this lens. With the (mis)nomer of the "secret handshake" lens, it's a collectors item. And maybe one day, I will buy another one to see if I can find why it's liked that much.
