I love the fact that there are always people on this forum, who will take a 100-dollar lens and make a point of saying that it is not as good as a 1000-dollar Nikon AIS that they have. But we are talking about a 100-dollar lens!I just got back my first roll of slides shot with the Vivitar 100mm. The sharpness is absolutely stunning. I blew up one of the shots to 8x10 (after doing some cropping) and got excellent clarity. A lens, and a macro at that, in this price range cannot be that sharp. I don't find the 1:1 attachment that much of a detraction.

~Cosina 100mm MCmacro F3.5~ 2005-05-26 23:34:15 レンズ 以前買って結局返品した中古のAi micro nikkor105mm F2.8sの騒動の後も、ずっと「マクロレンズ欲しい」熱が冷めずにいたのですが、ちょっと非純正にも目を向けてみようかと思い、コシナのこの100mmを. With a price tag of $138 brand new, this piece of plastic and glass is many times cheaper than any other macro lens. Even further, this is the longest cheap prime available. You can't get a 135mm or longer lens with a price close to this. This alone makes the Cosina 100/3.5 worthy of getting a review.

I don't find the 1:1 attachment that much of a detraction. This lens is a great value.Out of the box, it focuses to a 1:2 magnification ratio, and it is very sharp at all apertures and ranges.
It comes with an accessory 'closeup' attachment, a single element lens like a filter, to let you focus to 1:1, but with the accessory lens, it loses a lot of sharpness. I never use it that way.It is light and inexpensive, and I have carried it around the world. It has a plastic barrel, and lost some trim in its travels, but it has always taken sharp photos, no matter that the lens now looks battered, nearly shattered.To get into macro photography inexpensively, but with a lens that will give you great results, this Vivitar can't be beat.
