Clean sensor
I had my D for years before I needed to clean the sensor, and I have a LOT of lenses. I just got the Sensor Swabs and Eclipse fluid. It was a bit nerve-wracking the first time, but it worked. Now I feel fine about sensor cleaning.

Clean sensor
I have seen a Sigma 18-200 when I have done a search through google and a Sigma 18-125. Can you please advice as to their relative merits. Thanks for your patience. :oops: Howard Yeah I bought a used Sigma 18-125 and like it a fair bit. I made comparison shots between the lower end of the 18-1...

Clean sensor
The Tamron 18-200XR DiII is a superb lens, a little slow on the ist DS but superbly fast on the K10D. Do noticable distortion, even at extremes, and good clarity / colour. As for lens cleaning I change lenses a lot in very dusty African conditions and agree with others, always point the camera d...

Clean sensor
Thanks to everybody for their suggestions. I think I'll have to save more of my pennies to get one of the Sigma lenses or possibly the Tamron. And I'll have to be more careful when changing the lenses I have to keep the sensor clean. Howard :) :)

Clean sensor
I have this lens and IMO it's very good compared with the price. The main problem I have experienced is that it has more barrel distortion at wide angle compared to Pentax 16-45mm and that the coating is not as good as in an SMC lens.

Clean sensor
What I want to know is how to clean the screen. My DL has had dirt on the top part of the screen from 2 months old! The sensor is no problem to clean since I bought Artic Butterfly. It is the focussing screen that is the pain for me. I wonder if dust etc gets into the top part of the focussing scree...

Poll: Who's replacing their 16-45mm with a DA* 16-50mm?
I'm more interested in a 200 f/2.8, the FA version is still available (B&H) but the smaller image circle version is probably lighter. Just a thought here, speculation on my part, nothing else. Pentax have never said any of their DA lenses have a reduced image circle, they only mention "opti...

New road map?
"........Pentax seem to be busy undoing the "crop factor" on their new lenses.." Well contrary to what a lot of people have been saying this was on the cards all along. That's probably why there is such a lack of decent wides for the 'APS-C' size sensor cameras. Things w...

New road map?
Honestly I think Pentax have made it VERY clear they will not be bringing a 35mm sensor out. They have just redesigned there whole lens lineup to suit APS size sensors. People dreaming of a 35mm sensor should swap to Canon if its so important to them.

"Digital" lenses
Please bear with me on this small ride: We've all been told that APS-C format digital SLR cameras have a smaller sensor than classic 35mm film frames. We've all also been told that this would mean a crop factor on the classic lenses and, consequently, lenses built specifically for APS-C sensors woul...

coating coming off lens
It looks as though some pernickety person has been over-enthusiastically cleaning it to the extent that he's removed most of the coating. Lenses should not be cleaned too aggressively, or too often. G

coating coming off lens
The lens itself is not scratched, I've taken the pic in a way to emphasise how that coating has come off. It definitely appears that someone has been over zealous with the cleaning. My guess is some type of solvent has been used. I have tried a dab of petrol (knowing that that won't affect glass) bu...

Pentax 50mm SMC-M F4 ?
I've never used one but I can't imagine a Pentax SMC prime being bad. see some other users comments I always refer to that site when I'm considering a Pentax lens, older ones especially. For some reason that link takes you to the older version of the lens, scroll down just a bit to find the ...

Wide angle lens for an ME Super??
Well, there are plenty of pentax 28mm lenses out there - A pentax SMC M 28mm 2.8 in good condition. shouldn't set you back more than about £40. Third party lenses can be had for much less and some of them are quite good. The joy of Pentax is if you buy the old manual lenses they will work on the new...

K10D prime lens choices.
Thank you for your reply, Yes, I do know about the Sigma 30mm f1.4. However, on DSLR's this would equate to 45mm, or 'standard lens' view which is probably my least used lens type with other formats although I DO use the 80mm with 6x6 sometimes. I find it interesting that there is such a lack...

K10 'shift and tilt' lens choices(?)
Hi Viewfinder, Don't forget that with the much smaller sensor, compared to 6x6 or sheet film, you'd get much more depth of field at all apertures anyway - if you want the tilt to maximise DoF that is... If you're looking to use it to control the plane of focus to minimise DoF, that's a differe...

Macro Lenses Advice Urgently Needed Please
Here is a few 'Tattie' pics, with the new Sigma 105mm' Didn't set up any lighting, it's just from the window. I was just desperate to get a pic or two. All shots at f32 @ about 0.7 - 1 sec, on a tripod. Next time I would use a white card for fill-in light. It's so sha...

It's so sharp, I can even see the dust on the sensor !!!! I was going to mention that, but you beat me to it. :D Looks like I'll have to up my game a bit. :roll: Butterflies about - must get a couple of pics. Congratulations on your windfall! Dan
