DA* 16-55 SDM

Sorry to hear you are not satisfied with your 16-50mm lens simonsteph. I have this lens and as a firm film chap and think the old Pentax lenses are better made and superior to the digital range, this is one of the few digital lenses I regard as being quality. So I would consider sending your lens ...

DA* 16-55 SDM

The DA*16-50 is a wonderful lens and sometimes I wonder whether I have a duff example because it doesn't focus spot-on all the time.... but it's sharp, and let Lightroom deal with the imperfections

DA* 16-55 SDM

I have had my DA* 16-50 for a month now and it is fast becomming my most used lens! I also have the DA* 50-135 and that is firmly remaining my favourite lens.8) I do find that the 16-50 doesn't always focus right, then I just focus again and it seems to get it right. For me focus is fast enough...

DA* 16-55 SDM

I too got the occasional missed focus but found the lens was front focussing when wide open, particularly in poor lighting. I dialled in a correction and now I would say its 99% spot on :)

Can I use MY 35mm lens on Digital SLR ??

Hello moonstomp, in a word Yes, I have the Pentax SFXn, brilliant camera, very underrated, like the trap focus on it. However, you can use your 28-80mm AF lens on any of the Pentax digital bodies, but with the sensor used it becomes effectively a 42mm - 120mm, auto focus works with no problems.

Another Teleconverter question...

Will a TC (Sigma or otherwise), when used with my Sigma 70mm 1:1 Macro, convert it to an effectively 140mm 2:1 Macro or will it be a 140mm 1:1 ? The TC only doubles the focal length but you will keep your focus range, the subject will be 2 times as big at the same focus distance so you're right.

DA* 55mm SDM

I'm looking to get a prime at this focal length and am drawn to this one (especially as my new 2x converter will work the SDM, or so I'm told.) However, I'm not sure whether it's a good buy and, as I have a K10D (1.3 firmware), if the focus problem is still there. Any advice would be greatly appre...

DA* 55mm SDM

The one I tried appeard to be back focusing on my K10D @ F1.4, then again, so did the Sigma 30mm F1.4! I agree with John, the FA 1.4 might be a better option. Then if you were a K20D owner, you could change focussing for each lens independently!

sigma 150-500mm dg hsm

thats what i thought, but i also find the focus more accurate for small birds on the 170-500mm, i had problems with the 150-500mm for small birds, or maybe thats because i had to use f10,

sigma 150-500mm dg hsm

Is there a chance that you could take it back and get another just in case it is the lens at fault. I tend to agree with you about the HSM. I find that it does hunt for something to lock on to, especially when photographing a feathered friend. The HSM is certainly quiet but I find that the non H...

sigma 150-500mm dg hsm

I do like my new lens alot but often think whether I should have kept the 170-500mm as it was very reliable Paul :) One more point for the 170-500 one :D. Mike, you as the King of Teleconverters with an encyclopedic knowledge of them, and reverting back to our ongoing chats for longer ranges, ...

cheers guys, i brought it of loskeran, and he got it from srs, and he was good enough to give me the reciept, i have emailed srs twice and have not had nothing back, i would of thought that the 150-500mm should be as good if not better, i would be well pi**ed if i paid £720 for it,

It's just not Scott that's having problems wth the 150-500. I bought the same model from SRS a couple of weeks ago and it's displaying the same problems. The images are really soft when compared to the Bigma I used to own and the out of focus areas are showing a smeary, colour-bleeding effect. ...

The original only went back on Saturday so Chris probably won't get it back until either today or tommorow. I've e-mailed some sample pictures to them illustrating the problem so I'm hoping that they won't have to send the lens away for testing. I'll be using the lens for cricket (for the loca...
