Pentax lenses price increasing by 15-90%?
Lots of speculation too that Pentax were locking people in with rebates on K5s just prior to the increase, and/or that Pentax are about to release a super camera which will justify the prices... Would that the the April Fool K-3 I wonder? Be great if it really was a K-5 clone with a full frame se...

Pentax lenses price increasing by 15-90%?
Mark, you seem to have an almost religious faith that Pentax know what they are doing... I have a religious faith? Seriously? Sure, big companies make mistakes. Even so, nine out of ten mistakes don't kill them and if it's disingenuous to suggest people shouldn't be distraught about what they per...

Pentax lenses price increasing by 15-90%?
APS-C is actually a very usable format which first saw the light of day in film cameras. It didn't succeed in replacing 35mm partly because they never brought out any really good APS-C bodies, and partly because people already had 135-format kit, and didn't want to change. Now, APS-C digital cam...

Jessops fall out with pentax
Shaun - my interpretation of what you've been told is that Jessops are trying to apply pressure on Ricoh Pentax to come up with a marketing strategy that will re-enhance the Pentax brand name. As a retailer, they probably don't really care whether they sell more Pentaxes than Nikons, etc - but I hav...

Is this a good IR filter for my Pentax k-r?
The R72 filter will remove almost all light apart from IR, so it's the right filter for the job. On film then you just need some IR film, no problem. On digital it depends how much IR light the camer's own filters will allow through to the sensor. Some DSLRs are better for this purpose than other...

Updating from K 20
If you are considering full frame, then this would need serious investment as your DA* lenses would heavily vignette. Recent FF cameras, alas not from Pentax, usually have the facility to automatically crop images from APS-C lenses to avoid that. Obviously one wouldn't get the full value of the FF s...

Pinhole day
I might have a go. Some tips I have discovered in the past: 1. make the hole very small, clean and sharp (no burrs) 2. try making a telephoto by mounting the pinhole on the end of a tube (IRC, I got '200mm' with a toilet roll) 3. Use foil for the 'lens'. slightly thicker foil from wine bottle or...

Pinhole day
I'm using macro tubes to bring pinhole bit further from sensor.. the same as toilet roll... :D

If I had £6000 I would buy this
Did you look at the results at 100% crop? As the links provided by Mike-P and Puma gave, this is quite a different concept from a colour sensor in terms of resolution.

I would (and did) save £5400 and get a Fuji X100 which is quite amazing. A simple RF style camera which can function rather like the Leica you refer to. The quality of the images certainly gives my K5 a run for its money and the quality of the JPEG out of camera are quite gorgeous although I usually...

But the Fuji X100 can offer mono only and also has some swanky sensor that does it better than other marques so I can't see how that's different to discussing a Leica camera and technology. Just out of interest and to get back on topic which Pentax model is proposed with this feature? Mike

If I had £6000 I would buy this
Nikon have been flirting for years with the idea of an interchangeable sensor. I think the worry is that it may cost as much as an entire camera. I think the idea has merit. If you could carry one or two bodies with a 'normal' back, mono back, infra-red back, high ISO back, low ISO back, etc wh...

If I had £6000 I would buy this
I can see it selling to a fair proportion of potential M9 buyers, after all buying an M9 is a statement of intent for most and making something more exclusive only adds to the legendary status. I'm sure a few pros will actually get the benefit from the small difference it makes compared to a bayer f...

If I had £6000 I would buy this
Given that Harleys are appalling motorcycles as motorcycles and trade only on their iconic status I don't think this is a very simile. A Honda Golden Wing (is it - that big one) has tremendous style and quality of manufacture and are iconic in their own way. And I can afford neither. I understand...

Ken's discussion is intended to be about having black and white only sensors Of course, it depends on the price. Some reading material on the topic: B&W conversion (panochrome Bayer filter removal): http://www.maxmax.com/b&w_conversion.htm M monochrom: http://www.luminous-landscape.com/r...

If I had £6000 I would buy this
Going back to the original point (sorry) I wouldn't bother buying this camera. I would (as I said earlier) buy an SLR with an interchangeable back so I could have a mono sensor, but only if it was as good as mono film. Until then I reckon it costs me about £5.00 a roll to buy , develop and sc...

Removing the AA filter removes the slight blurring that is introduced to avoid moire effects. This has nothing to do with colour. It is why all digital images are slightly soft direct from the sensor and some sharpening is needed. The sensor always sees in black and white, the colour being introd...
