Macro different mm
Unlike most "standard" lenses though you can just keep moving closer, and closer, and closer to your subject - until the front element is almost touching it in fact. This gives you the option of being able to take some very interesting perspectives in your everyday photography and it's great with fl...

Makinon MC 135/2,8 (K-mount)
Thank you both. I guess I'm fortunate to have a good example then :) It's interesting how even the low cost lens were supremely built back in the days. regards, Luka

Makinon MC 135/2,8 (K-mount)
I seem to remember reading that 135mm lenses were one of the easiest to make a decent stab at, with almost no complete dogs. Older lenses do tend to produce cooler colours than current ones. I generally put it down to different coatings, plus I get the impression that photographers then were aft...

Makinon MC 135/2,8 (K-mount)
I've got the Makinon 135mm 2.8 too - is yours the macro/close focus version? I've found it to be a really nice lens to use. I actually got it from my uncle along with his other film-era pentax lenses and, as it had an oily iris, was the first camera lens I stripped down completely to clean and repai...

Makinon MC 135/2,8 (K-mount)
[quote:3496ace15f="Lilliz"][quote:3496ace15f="flat4"] If it works with the K10D it'll work with any Pentax dSLR. K. Thanks K. I would have thought so myself, but I took it to a camera shop and the guy fitted it on a k7 and told me it wasn't compatible, so i wasn't sure. He might have been a pe...

Pentax DA 35mm f2.8 Ltd Macro lens
A rather appropriate name for the pub in the picture. Asahi Optical Co., 'Asahi' = The Rising Sun Wow, well spotted. I wonder if horses have anything to do with pentax? And yes, back on topic, the DA35 is a great lens (rendering, sharpness, colours, macro) and might be all one needs on a came...

50mm Lenses
I've not listed all the lenses, just a selection. Pentacon Prakticar 50mm f1.8 Decentering: 10% MTF 10 lpm 88% MTF 40 lpm 46% Distortion: -1.5% That's the only one, hope it helps! It does actually :) I'd always said the Pentacon 50 was very similar to the Pentax M50/1.7 and now I ...

Advice on upcoming lens purchase
Hello, I was also torn between the Pentax 50-135 and the Tamron 70-200. I didn't look at the Sigma one, because I actually don't like the feel of sigma lenses in general. but this has nothing to do with the quality of the lens. I ended up buying the pentax, for various reasons, one being tha...

Another vote for the SMC-DA*50-135. Unbelievable lens - couldn't do without it now! It's wonderful for flowers and landscapes. Close focus distance isn't that close (but closer than some in that zoom range), so you won't get macro shots without extension tubes (which have to be used in manual focus...

Advice on upcoming lens purchase
I used to use some generic 72mm close up filters. They were ok... a fair bit of CA was introduced, plus some distortion across the field. But they were light to carry and easy to use! My intention was to replace the SMC-F 100/2.8 macro with the SMC-DA*50-135 + extension tubes. Actually, I probabl...

28mm Lenses
Back to 1981/1982 again and some 28mm lenses compared, and I think one common misconception turned on its head. Lens name - MTF value at 10 lpm - MTF value at 40 lpm Canon FD 89% 42% Zeiss Distagon 92% 57% Hoya HMC 87% 47% Leitz Elmarit-R 86% 34% Makinon 86% 31% Nikon E 86% 40% Pentax-M ...

28mm Lenses
Hey Jon, I'd have to try it out again; it was a while back. But I just recall being uninspired by the rendering. But I do like the 28mm focal length on APS-C.

28mm Lenses
Thanks for posting the test results for these 1980's lenses - very interesting. I haven't used any Pentax 28 mm lenses but I do have the SMC A 24/2.8 and it's a beaut (in my book anyway). I'd love to know what the testers thought of that lens back in the day. Any 24 mm test results from your old...

Da 35mm vs DA 40mm
I wonder if anyone has been able to make a hands-on comparison of the DA 35mm f2.8 and the DA 40mm f2.8? I have a copy of the DA 35mm and while it's a super lens in many respects I'm not sure it's quite right for me. Being a macro, it is quite hefty and I have found that it can be a little slow to f...

Da 35mm vs DA 40mm
That is the strangest lens hood/lens cap arrangement I have ever seen. Does the trick though! The daftest thing is the Pentax logo on the back of the lens cap. It has a 30.5mm thread so I can use all the filters I have for my 500mm mirror Tamron. Truth is I've never used them ever, apart from the...

Da 35mm vs DA 40mm
it can be a little slow to focus and hunts around a bit when used for general walk-about stuff Seriously, just practise manual focussing. It's faster - only you know the precise point you want to focus on - and it's more accurate. The raison d'etre of the 35mm macro is that it is a capable gene...

Da 35mm vs DA 40mm
Seriously, just practise manual focussing. It's faster - only you know the precise point you want to focus on - and it's more accurate. ...and I remember when auto-focus first came out - we were all very sceptical; surely these cameras couldn't do a better job:P Trouble is, we've lost the split p...
