SRS Great Service
I have not been on here for too long, but recently I was concerned that my K5 may have a sensor stain, so I returned it to SRS and they checked it out for me and it was ok just a dirty sensor. Then they cleaned it for me and sent it back FOC - what great customer service and a brilliant business....

Ink Jet flow systems
My last printer, Epson R300 was bought at a computer market along with a cheap continuous ink system (the guy even fit it for me while I browsed the rest of the market) it lasted about 5-6 years and cost me about £25 in ink over that period, I had no problem with colours on the prints and although t...

MX1 advert
I got to see and gave a little play with an MX-1 in the newly reopened Jessops in Oxford Street. They had a nicely laid out Pentax section. I found it suprisingly large, especially compared to the Pentax Q. The rear tilty screen seemed useful but competely incongruous to the otherwise retro des...

I got to see and gave a little play with an MX-1 in the newly reopened Jessops in Oxford Street. They had a nicely laid out Pentax section. The basic idea has a lot of potential but the size of the camera really warrants a larger sensor. It seems to me that Hoya Pentax have designed a very plau...

One thing possibly in the Pentax's favour is its use of the conventional Bayer array on its sensor. Adobe has had two shots so far at rewritining algorithms for Fuji's X-Trans to get decent results in Lightroom. Otherwise, I agree with the above and would consider the MX-1 a little behind the curv...

Is it April 1st yet?
a new mount for pentax would not surprise me.... the rumour of the demise of the kmount is bs... but... a meduim format sized k-01 taking lenses with a new mount would make sense... esp if released with a 645 lens adaptor... think about it... shave off the mirror box from the 645-d tack on a short...

Pentax returns to Jessops
Happened that today morning I was passing by Oxford Street Jessops branch and first noticed guy in jessops t-shirt cleaning window, that was surprising, then noticed plenty of suited people inside, "party" ongoing and a tv transmission car in a nearby street, just later I found news about re-opening...

Printers
While we're on the subject of printers, I've got a related question. I used to have one but used it so sporadically that the cartidges tended to dry up between prints - at the same time, even though it ended up more expansive than using a lab given my low-volume printing, the instant response meant...

"What goes round, comes around" - it must be F8
I believe for my output purpose it is important to maintain full control over ISO. Certainly on the K7 the jump from 100 - 200 - 400 would be significant. So Tav wouldn't give that full control. Just like a film photographer wouldn't bung in any old 100 or 200 film when taking a considered shot for ...

PTTR
ETTR (PTTR) was introduced as a method of maximising dynamic range of early Digital sensors. There's no need for it these days IMO. In contrasty scenes I always underexpose to try and avoid clipping. Cameras like the K-5 have great dynamic range to allow aplifying the shadows. :) This is only...

ETTR (PTTR) was introduced as a method of maximising dynamic range of early Digital sensors. There's no need for it these days IMO. . Can we agree on 'there's usually no need for it' ? In contrasty scenes I always underexpose to try and avoid clipping. That isn't really in conflict with ETTR. ...

Pentax lenses on micro 4/3
One advantage of the Q is the tiny sensor, which means that cine lenses and all sorts of wonderful obscure lenses will fit and cover the format. Thinking about it though, I haven't seen that many, if any, great images come out of these experiments, with any combination.

Price Check - damaged k20d
Hi could you indicate a price range for a second hand k20d body with a sensor damage? It takes pictures but it developed a sensor fault some time ago. The fault shows as a bright spot the size of few pixels on the photograph, with a thin (1-2 pixels) line across the most of the frame. Depending on t...

Price Check - damaged k20d
Personally with something like that I would stick it on Ebay and let the camera find it's own price. As a repair project it's probably only worth around £50 (allowing for a new sensor fitted by JPservices) but to someone else who wants to buy a camera for converting to IR then it would be worth a lo...

megapixels
jpeg files do not store all the information available. areas of the same or similar light are stored in a kind of shorthand. Colours and shades can be dithered out of the image. If you try to recreate what the sensor saw from the jpeg file you will fail, some data is discarded. The file size is a...

Does anyone have an idiots guide to megapixels? i know i probably dont need to know too much about them but there are a couple of things which confuse me, one being that if i have pentax k-30 with 16 megapixels how can i produce photographs which are 20 and above? and if i have a shot which is 18-2...

It's not easy to determine image file sizes based on the sensor size. Quite apart from the image itself, there's a lot of other information recorded about the camera settings, known as EXIF (EXtended InFormation).

megapixels
OK I'll have a stab at explaining. If your sensor is 16 megapixels you will have 16M (16*1024*1024)pixels in that sensor. The camera produces a raw image from this storing the sensors resolution in bits for each pixel, with typical sensors storing 12,14 or 16 bits per pixel. Lets assume our ...
