if you had to sell either a DA*60-250 or FA* 80-200.......
I have both the DA*60-250mm 1:4 and a Sigma EX DG OS 70-200mm 1:2.8. The latter was bought because I had serious problems trying to focus the 60-250 on my K5 in dim lighting of night time car races. The Sigma was a vast improvement, then came the K-5II, and in combination with the Sigma I wasted ...

D* 16-50 or Limited?
Whilst the Tamron is good I wouldnt put it in the same league as Pentax primes or comparable to the 16-50mm. I had the tamron for three or four years and was constantly put off by bad reviews of the pentax. It wasnt until i bought the 16-50mm that I realised what I was missing. Better build qu...

Teleplus mc7 2x macro converter question
Hi guys, I've just received delivery of my used lens as per title. I have a couple of questions that hopefully one of you people will know the answer to. 1. When I switch the camera on it asks for the focal length. Is this the focal length of the lens attached to the converter or the combined l...

Teleplus mc7 2x macro converter question
Darren, regarding the numbers - I have recently got a Vivitar 2x macro converter and it also has green and white numbers. They refer to the magnification when using it with a 50mm standard prime lens - white for when the lens is set to infinity, green for when the lens is set to its closest focus di...

Teleplus mc7 2x macro converter question
Hi Philip, thanks for that. I've just had a play with it and that seems to make sense. Are you able to select the focus type? I know it's manual focus only, but I don't seem to be able to change the focus area from spot focus. I assume this is normal with a manual focus converter?

Question about M42 to PK adaptors
If we think back to when the K mount was introduced, many people would have large numbers of screw thread lenses. The Adapter K effectively converts a K body into a screw mount body to they could update the body and still use the lenses. That's the way it works. You put the adapter on a lens and ...

Sigma 28-70 F2.8 EX
I'd suspect that you'd find the Sigma EX 24mm-70mm or ... Were there some compatibility issues with that lens on Pentax DSLRs? It would not auto focus or stop down on the early versions before Sigma upgraded the lens.

Lens Suggestions
The DA 55-300 would be an excellent choice as a second lens. It is by far the best of the budget zooms in that range. I have taken some macro like photos of butterflies at the 300mm end from about 2m away, and it obviously will cover things much farther away. As for landscapes he kit lens is a very...

Lens Suggestions
The Pentax 55-300 is an excellent performer and I would recommend it for a wildlife starter lens. The Sigma 150-500 is a good lens for wildlife, especially if you want the photograph small birds. Technique with steadiness and balancing high shutter speeds, aperture to control depth of field and high...

Tamron 17-50 f/2.8 vs. Pentax DA* 16-50 f/2.8
I'm seeking some opinions here. I'm considering upgrading my Tamron 17-50 to the Pentax 16-50. This would give me the DA* 16-50 and the DA* 50-135, both weather sealed, as my main two-lens combo. It would involve parting with both the Tamron and the Pentax 18-135WR to finance it. The only thing h...

Tamron 17-50 f/2.8 vs. Pentax DA* 16-50 f/2.8
OK I just read the conclusions of that review again, been a whilst and I remember it being fairly negative as have most reviews of the 16-50mm I know because I owned a Tamron for nearly four years!!! Whilst the Tamron had good IQ quality the build quality was truly dreadful, if you search the int...

worth paying double to get a Siggy 120-400 over the Pentax 55-300mm?
I am not a massive telephoto user but I do like going walkabouts with my friend shooting wildlife and enjoy rutting season and like the odd wednesday at mallory park.. in Canon I did this with a 70-200 L glass and yes I had to crop with small birds but they kept the sharpness good enough.. now...

worth paying double to get a Siggy 120-400 over the Pentax 55-300mm?
The Siggy is in my opinion a superior lens to the 55-300. Quieter focus and the better reach factor.

worth paying double to get a Siggy 120-400 over the Pentax 55-300mm?
Thanks all. 120-400 ordered.. was the way I was leaning toward as I have never had anything over 300mm but mainly the longest I have had and for the past few years is 70-200 so it has that something new feeling. Did you buy it via the SRS evilBay outlet store as delivery is free as opposed to claimi...

Portrait lens
Hello Gary, I'm not sure if the Takumar 135mm F3.5 is the same optically as the M version. I would doubt it as there's a good few years between them, but I know someone on here will have the answer. What I do know is that the Tak 135 F3.5 is a very sharp lens that is great wide open and rivals the...
