Sigma 70-200mm f/2.8 EX DG Macro HSM II
Hi Hefty Thanks for the welcome. Well it says in Digital Photography Review about the Sigma lens "Pentax DSLRs which don't support SDM lenses will lose out, and only be able to focus manually (in other words, the lens is effectively of KAF-3 mount specification)". I thought the K200D had KAF-2...

Sigma 150-500 and other info...
Hi Everyone! I have just had a shipment of Sigma 150-500's arrive. Just a gentle reminder that when ordering from our website, please include your forum ID so we can process free postage. Another heads-up - most prices are increasing by 15-25% in January / February (or when stocks run out) ...

Sigma 150-500 and other info...
I am still awaiting info from Pentax, but... The GPS is a seperate module which is powered by a rechargeable lithium ion battery. It is not Pentax branded. I spoke to Steve at Pentax to find out more and he said that you press the button on the GPS once you have taken the picture. The GPS d...

Sigma 120-400 f4.5-5.6 APO DG HSM
I've had this lens, albeit in Nikon fit (stop booing at the back there!!). My impressions were that it was a nicely built lens, lovely finish to it like all the latest Sigma's, and the OS system worked a treat although that isn't applicable to the Pentax version of course. My only issue with i...

The 50-135 is tempting too. If it started at 35 I would feel happier as I fear I will swap lenses too often and drop one. 35-50 can be solved by walking back and forth BUY THE 50-135 :twisted: :lol:

Can't be sure about that. Do you have a Pentax fit Adaptall 2 mount as there isn't one with the lens. You might be better looking for a manual focus Pentax macro lens which will be much more compact and will be sure to work 100% correctly.

Mike...I am looking at the 72B for use with my K10. Would you reccommend this lens. I only intend to use manual focus. Presumably I would need an adaptal mount to Pentax. regards Ronald.

Anyone using Pentax M 50mm F 1.7 on DSLR still ?
i've got one of these... got it for macro, but it also comes into its own when the light drops. yesterday i was playing with some very accomodating swans... guessing the focus distance and holding the camera on the ground next to the water's edge as they fed. got some interesting results. it's al...

Anyone using Pentax M 50mm F 1.7 on DSLR still ?
My testing of this Pentax M 50mm F 1.7 lens is still ongoing:D with my pentax k20 I purchased last month. I have only used pentax film camera and compacts in past so do not have any experience of using manual focus lens on digital body. Still can't find any easier way to use this lens on my K20,...

Anyone using Pentax M 50mm F 1.7 on DSLR still ?
1) I assume you have the "allow aperture ring" (or whatever it is called) in the menus set to yes, otherwise everything shoots wide open. 2) Fit the lens with the camera turned off, and then when you turn it on the camera will ask for the focal length for the SR system. 3) Focus is a bit of a ...

Anyone using Pentax M 50mm F 1.7 on DSLR still ?
Well sorry to spoil the party, but I find using M series lenses a total pain in the butt and have sold them all. 'A' series and even SMC Takumars are much easier to use. Personally I find the Pentax-F 50mm 1.7, which is according to Bojidar's site, optically the same lens (slightly different colour ...

Anyone using Pentax M 50mm F 1.7 on DSLR still ?
The M and "K" lenses do take a little more effort. Depending on what focus screen you use (i now use a split prism) the meter reading can be a bit off, so you need to use the histogram. But this is no bad thing, having to examine your exposure after each shot is actually quite a good discipline. ...

Anyone using Pentax M 50mm F 1.7 on DSLR still ?
You get the same focus feel with Pentax-A lenses, though there isn't a direct A equivalent of every M and K lens. I wouldn't bother with an M 50mm f1.7/f1.4, but will hang onto my M 100m f2.8 and K 135mm f2.5. Example from the latter (at f2.5):

SMC-DA 17-70 f/4 A:[IF] SDM
I found it very hard to find a review for this little beastie... there were a couple, but not that many test shots. And then I made the mistake of reading Rice High's blog on it :P :D Still, SRS did a splendid job of shipping this to me (thumbs up again for SRS and the team!). With the cash back ...

SMC-DA 17-70 f/4 A:[IF] SDM
It is a wonderful lens isn't it? I can't compare it to anything more than the mk1 kit but wow I love this lens. No focussing problems with it at all. i am very happy with it! And that without the cash back :D

SMC-DA 17-70 f/4 A:[IF] SDM
Thanks for the info Matt, I was wanting the 17-70 when it first came out. The reviews were a bit mixed, so I put it on the 'back-burner'. Going to go for it now after your experiences, this would be my ideal range, just wish it was a f2.8, but then again, if it was, the price would be out of m...

Sigma 10-20
They do look a bit soft, but can't be sure from those reduced-size pictures. It would help to post some crops at full size and state the settings. Preferably post a good example from another one of your lenses too for comparison to eleiminate any issues with software, etc. Focusing can be tricky ...
