Tamron, Asahi, CZJ? Which is the best?

I have just received the lens from Bosnia and taken some sample pictures. Here they are. No postproduction, of course. I am satisfied with the quality despite the fungus on the back lens. I will take the glass to a tech next week, and hope for the best. The front cap may not be a problem, as a clip-on cap almost fits. A minor tweak will help, I think.

I concur. I took a look at some photos on the net showing how fungi affected picture quality. The blogger wrote as if fungi would have totally destroyed the pictures' quality, but I did not see any difference between the sample pictures. My tech wrote that he uses special techniques to get rid of the fungi, and attached some pictures of his previous jobs, so I trust him. The main concern is how to protect the front lens? It the filter thread is bumpy, I won't be able to put a cap on it. I have asked the seller about this, but have not gotten any answers yet. However, it is possible, that the dent is so small, that I won't have any problem fitting a cap into it.

Well, I risked it for 51€. This is the "dirt cheap" category for me, even if the lens is not in excellent condition. The mai problem is how to protect the front element, because it does not have a cap.

Well, I will have it cleaned, and then will let everyone know how things turned out. Thanks for all your answers and help!

Pentax SMC 135mm f2.5 Pentax-K Telephoto Portrait lens | eBay

Here is this one for 51€. I am a bit concerned about the fungi. I asked a professional, and if he gives me the green light, I will buy this one. The dent on the front element does not seem to be a major problem. Or is it?

I started a thread not so long ago about zoom teleobjectives. As I don't have enough money for those, I have been looking for primes. However, I just can't decide which one to buy.

The last one is converted to fit the PK mount. However: is it possible that the conversion affects image quality?


Thank you very much for your help! I am really lost.

Help me buy a good tele, please (Tamron or Sigma or Pentax?)

I assume you use the lens with auto focus, am I right? Is this lens capable of focusing so fast that you can capture live sport action?

By the way: as almost all of you gave me the advice to buy an expensive lens, and not try to find the kind of "I have a cheap but breathtakingly sharp bla-bla" lens, I will invest in a serious glass in the future. Thanks everyone for the answers!

Hi Anders! Thanks for your answer. However, the lenses you recommend are sold for well over 500€ (the Pentax for nearly 1000€), so they are out of the game.

Just the basic facts, as Pink Floyd sang.

I can't decide between these lenses. Well I can, of course, but some advice would be very useful. I would like to shoot soccer games outdoors and also indoors during winter. I have a Pentax 16-45, and I am satisfied with that, but would like to replace my older, manual focus lenses with one of these (prices included):

Tamron AF 28-200mm/3.8-5.6 -- 100€
Sigma 50-200mm /4.0-5.6 DC OS HSM -- 100€
Pentax DAL 55-300mm f/4-5.8 ED -- 110€
Sigma EX 2.8/70-200 mm APO -- 400€

Of course I want the last one. But I really don't know if it is reasonable to give out so much money for a lens. I don't know if I ever need such a beast (I am not a pro).

Thank you for your help!

My daughter watching the snow. The pic was taken with my phone, because I did not have my K-01 back then.
It is like a Vermeer painting. Isn't it?

I have bought a lens because I could find someone who had it previously, and sang operas about its quality. At least we know now. :) I am really curious!

I have just bought this lens on eBay. I don't know if anybody is interested in galvanizing life into this topic, but I will send some pics taken with my K-01 once I got the lens. I have asked a friend of mine about this one, and he said that its quality can be compared to Canon 70-200IS USM I. I have not heard about the latter lens, but then I found out that the Canon was an extremely good AND pricey one. While mine was €57.
We'll see.
