As I like to use my lenses with both film and full-frame digital cameras, I've been looking for a good standard zoom with an aperture ring. This lens has one, although it doesn't look like it on the product image on this page. So when it showed up on Ebay for around 100 €, I gave it a try. When I...

I have two samples. One is my beloved one which I bought cca in 2009 as slightly used. 2nd one is backup since my first lens developed some AF disease over time. I started using this lens on K20D and later I added K5 and K3. With K20D everything worked well, because that camera had no live-view con...

While having Sigma 70-200/2.8 HSMII for many years, it developed some AF disease and it usualy takes few minutes to warm up the AF motor to work properly. So I got mysel a backup lens until it will be serviced. This Tamron 70-200/2.8. And I'm pleased by the image output which is in some cases maybe ...

General impression: with K1 it has good handling balance, but in general its big and heavy lens. Lens comes with very practical bag, bag is a bit solid it will make a good protection for lens. Build quality very good, lens is robust, except front lens cap. I have no idea how front cap could be so...

First, one can find sharper lenses for the price. 125mm Zeiss Sonnar (appr. 100$) for example works much more accurate. Sharpness and contrast are quite low. But there is only the Meyer Görlitz with the special dreamy look and this exceptionell bokeh. If youre looking for this very special gem - you...

This a strange lens, the idea is nice, integrate filters in a lens but the ergonomics are poor and optical quality too. Filters prone to opacity with age. Fun to use, but very poor results. I got mine for free in a bulk of photo stuffs but happy not to pay for it.

I really wanted this lens to be sharper than my Tokina AT-X SD 100-300 F4 but disappointingly it is not. It is quite soft at F2.8 and gets better by F4. At F5.6 it is very sharp. My Tokina AT-X SD 100-300 F4 is actually sharper at F4 than this lens. But by the time you get to F5.6 both lenses are eq...

I'm reviewing the black (with white or green numbering) 50-2 M42 lens. These can come in gloss black or satin black finishes with minor external measurement variations due to factory manufacturing differences. Firstly, this is certainly not a "pancake" lens as pancakes are flat and pancake lenses ar...

I have the Auto-Tamron F version with 6 blades in the Iris. 4 elements in 4 groups A very good 135mm from the 1970s which shows CA in the digital cameras Well built, solid. Focus ring was a bit stiff and the built-in hood had good friction. Nice color rendition and sharpness, with some blue C...

I bought it used from a fellow Pentaxian on the UK user website. It is in immaculate condition, but my word, what a lens! I've no need of any primes with this lens, it is so sharp and renders beautifully. N o need to say anything further.
