Sensor resolution, lens resolution and image quality
Thanks, pretty much what I thought. I agree about the final image being with the photographer but artistic quality can't be done by the camera and lens (well not really) so that bit is a constant. I'm sure the top end modern lenses will be the best bet but I have to say I was amazed at the quality I...

Sensor resolution, lens resolution and image quality
Glass keeps its value much better than the majority of bodies. Buy the glass and await K5 price reductions :wink:

Sensor resolution, lens resolution and image quality
My advice? Dump the 3rd party older glass. While modern lenses may be better the gap is a lot wider when compared to generic wearer-of-many-badges lenses than it is when compared to, say, SMC Pentax or Pentax-M lenses. Definitely keep the Takumar and Pentax lenses, the Takumar may be old but ...

Sensor resolution, lens resolution and image quality
I'm not sure I'd dump them! I've just done some pretty controlled comparisons at F8 and 200mm and the Adaptall 60-300mm matched the Pentax 55-300 DAL and the Tamron Adaptall 80-210 was pretty much the same at that focal length. The Takumar was best but then it is a 200mm prime. Having said that I w...

Well if you want to dump the Chinon 50mm, please dump it in my direction!

Lens Advice
I have the Sigma 18-200, I origionally bought this over the Tamron 18-250 because the Sigma focussed faster. Since owning it for some time, first on a K10D where it did stay on the camera most of the time; it also worked very well with the Kenro 1.5x conveter. Since getting the K7, it has only b...

Pentax lens on Canon body question . . .
John, I think that Canon lenses are of a larger diameter than the Pentax mount which might make marrying a C lens to a P body somewhat challenging. The 40D is actually a very good camera with a 10Mp CMOS sensor, live view. My son produces some really good work with his 30D, and the 40D is better. ...

Tamron 18-200 macro
Hi friends, I have, yesterday, ordered a new Tamron 18-200 tele/macro lens for my K10D. At present could not afford 18-250s and 18-270s. I have a 18-55 kit lens and a 70-300 which i found very risky to change frequently as i would expose the sensor to dust. Any encouragements pl?????

Static charge - how to remove?
Fibres left behind aren't a problem - a quick blast with a rocket blower or twitch of a soft brush will remove them. I have a Hama-branded lens pen and would recommend it as the first thing anyone should buy after their camera. Best device ever for cleaning fingerprints and greasy marks, there's ...

Static charge - how to remove?
This is the first time I've heard of such a thing - certainly my 55-300mm doesn't attract dust. If you need to disperse a static charge theree are small guns, carbon fibre dusters and probably other solutions. Perhaps a clean with lens cleaning fluid would remove whatever is causing the problem.

Static charge - how to remove?
Knowing at least a little bit about static electricity I have come up with a theory that it is just because the lens has been (as stated by the seller) sitting around unused for several months, thus giving a static charge an opportunity to build up. Regularly cleaning a lens should disperse any smal...

35mm limited for K5?
Hi guys, Long story short: I'm returning my K-5 + kit lens due to sensor stain and decide to buy a K-5 body only + 1 separate lens instead. Right now I'm very inclined toward the DA limited 35mm f2.8 macro. The following pro/con comes from what I have researched. Price: £375 (SRS) Pro: go f...

My new 150-500
I can't remember whether I tried it with centre spot AF, but I'm pretty sure I did. I can focus it easily enough manually but that doesn't really help for wildlife! I did hear a suggestion to leave the lens hood off but couldn't really see why that would make a difference. If the hood cut down th...

Historical prices
Having recently bought a Kx rather than a Canon (EOS 33V + three lenses), I bought partially because of the excellent value for money of Pentax DSLR bodies coupled with the vast number of possibilities lens wise on the used market. I can't afford to buy premium priced new lenses at Canon/Nikon pric...

What's the appeal of 40mm limited?
I suspect they picked 40mm for a pancake because of the old Pentax-M 40mm lens, but I agree it is odd. To give the same effect (of an ultra-compact standard lens) they really need to make something with a shorter focal length. If they were to release a K5-sized body with a full frame sensor it would...

What's the appeal of 40mm limited?
The 40mm is my favorite Pentax lens and is the lens I always left on the camera by default. There is something about the AOV on a cropped sensor that I really liked. But I can't tell you why.

My first mount conversion
I've been after a Meyer Optik Orestor 100/2.8 for ages but had lost out a quite a few to the eBay snipers. A coupe of weeks ago, I found one in a lot with some other, random, fungus infested lenses and won it from a reasonable price. What wasn't mentioned in the listing and I didn't spot from th...
