Post noise reduction - jpeg or raw?
I was under the impression that 12/16bits is what Raw is about, hence there is no compression of the image from the sensor so a little more to play with. Rawtherapee just kept crashing on me, so not sure whether lightroom would work any better. Maybe its time to upgrade to a decent graphics card!

Pentax in Advanced Photographer
I nearly bought an X10 a couple of weeks ago but they have interesting ORB effects which I didn't like. (by the sea , in the fabulous British sunshine). Manual zoom 28-112mm F2 to F2.8 mmmmmmm. 2/3" sensor but Fuji EXR thingy. With a zooming viewfinder. Come on Pentax!!!! Make an X10 not a...

Rumour!!!!!!!!!
All Pentax+Ricoh need to do is: * Mirrorless camera. * Full Frame (using APS-C format lenses the camera "crops" the sensor for backwards compatibility) * Compatible with all Pentax lenses back to M's of yesteryears. * That Sony sensor. It can be done. Seriously. Anything less than that won'...

Rumour!!!!!!!!!
These compacts look good- Pentax thinking of actual picture taking with the addition of a portrait oriented shutter button. I'm not aware of any other compact with this and I am sure there are lots of portraits taken with P&S cameras so it does make sense. I thought Ricoh may drop the Optio monic...

Rumour!!!!!!!!!

1st impressions on macro photography & help wanted.
Hi, So I bought a pentax 100mm f2.8 1:1 macro lens on Friday and played with it over the weekend. Just wanted to share my first impressions. It's not as easy as I thought- lighting, camera shake, very narrow focus area. Magnification: Beofre I bought I read a lot of people saying you don't n...

Lens cleaning/repair
I've got a couple of old K series lenses that could do with an overhaul. Can anyone recommend a UK specialist for the job?

The 'sheep' reference refers to the fact that a lot of first time buyers of cameras 'follow the herd', (canon/nikon) rather than doing a little research to find an equally good or better alternative. One reason Pentax sell less cameras. This certainly explains how I and, I suspect, at least a few o...

Ricoh camera division to fall under Pentax?
I wonder if there will be a degree of integration between the brands if they are now in the same division of the parent compay. The Ricoh GXR modular camera has a module which accepts Leica M fit lenses - only manual of course - and others with simple adapters including Pentax. There have been...

Film vs Digital Books
Mmmmm! I'm going to stick my neck out and say "Not really". I sometimes refer to books on photography written fifty years ago. The relationship between ISO (or ASA/DIN as it used to be known) and shutter speed and apertures are exactly the same now as they were 100 years ago. Changing the val...

More rumours
There's no way they could keep five systems going all at once (Q, DA, FF, K-01, 645D) plus the Ricoh stuff :shock: Other manufacturers only have one or two!!! :shock: They are going to have to decide which basket to put their eggs in very shortly...... The DSLR's are currently being neglected. Camer...

Retailer Advice
If prices are a little higher at Park or SRS on occasion (and usually they are fairly competitive), then many of us, particularly in light of recent events, feel that it is worth the extra to deal with a proper camera shop. I'm referring to the sensor issue of course. G

Filter test with spectrometer
Very Interesting. I'll have to compare the spectra of my UV filters with what they've got. (I've only run the spectra on one to date and that in absorbance rather than transmission) They do have one minor error though - the Hot mirror used infront of the sensor to reduce the sensitivity to IR doe...

What is your technique to focus M lenses?
I would far rather use the screen on my K7, or purchase a K01 (which is even better as it has focus peaking) than resort to an expensive rangefinder system (with limited lenses to choose from). Live view is always 100% accurate as you are seeing 'what the sensor is seeing'. Hopefully Pentax will...

Finally taken the plunge
Yes get a tripod - but not a cheap one! Get the very best you can afford - it will last longer than your camera, or you probably. A second battery, even maybe a third, so one is charging, one is in the camera and one is in your pocket/bag just in case. Lots of memory cards. Lens cloths are c...

Imagine having all this on your own doorstep!!...
Thanks Smeggy, it really was a snap shot; or as close as you can get to a snap shot with a 500mm mirror lens. Although I've cloned it out, I discovered that sensor dust shows up as a black donut!

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...
