Colorful and expressive : UV Topcor 1:4 f=28mm Tokyo Kogaku

Cost: $20 (market price $20 or more)

Now that I have completed my collection of UV Topcor lenses, you can expect a few more reviews of this series. Again, it was a pleasure to shoot with this lens. Not having an aperture ring on the lens itself, but on the body or in this case the adapter, keeps on making it an adventure, as the adapter does not include any markings for f-stop. Most of the pictures were taken with the f-stop somewhere in the middle, like f8 or f12.

Also this lens has the same sharp and clean appearance of the other lenses in this collection. again with a black and brushed metal look.

The lens itself provides again a decent image quality, not fantastic, but rich colors, ok sharpness and some color aberration, but noting Lightroom could not fix. A pleasure to take pictures with.

As with the previous reviewed lens, the 35mm, we see strong flares when directing to the son.

It's not a great lens, but good enough to keep and protect it from the future.

A lens with character: UV Topcor 1:3.5 f=35mm Tokyo Kogaku

Cost: $20 (market price $20 or more)

After testing a few of the Minolta Maxxum auto focus lenses, it was a pleasure to play around with a manual lens again. And with the UV Topcor lenses, not having an aperture ring on the lens itself, but on the body or in this case the adapter, making it even more manual, as the adapter did not include any markings for f-stop. Most of the pictures were taken with the f-stop somewhere in the middle, like f8 or f12.

The lens itself is good looking, with a clean black and brushed metal look. I expressed my admiration on of the earlier reviews of UV Topcor lenses of the nice uniform look across the range.

The lens itself provides good image quality, something I did not see in the UV Topcor tele lenses. Rich colors, ok sharpness and some color aberration, but noting Lightroom could not fix.

Bokeh is rather unique and nice, but what really set this lens apart is the flares when shooting in the light. Some will say this is very bad for a lens, but in this case, it was a very specific flare, giving this lens all the character it can handle.

It's not a great lens, but it's interesting enough to have a special place when such flares are desired.

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.
