AP compare K5 sensor
Positive yes, but another pile of editorial rubbish from AP. Read it closely and you will find contradictions, statements that do not make sense and if you compare the pictures to the text, they do not match...more inconsistencies. I do not believe anything AP says in regard to gear.

K7 owners- a few questions?
Doesn't the K7 share the same (aged) sensor as the K20D? According to DXO the KX sensor beats that of the K7 (including DR) If video is not needed, perhaps a K20D would do just as well (and keep the Kx)? For info I've also considered a K7, but see myself missing the better ISO and DR per...

K7 owners- a few questions?
When the k-x came out i made the choice between a k-x and k-7, at the time i couldnt justify the k-7 as the k-x has better sensor and low light capabilitys. i would of been gutted buying the k-7 if a few months later they bought something else out....which they did, the k-5. if i had bought the k...

K7 owners- a few questions?
And not only that the Dynamic range is two stops better two 14bit v. 12bit More bits doesn't automaticly mean more dynamic range it simply means there is more room for it but if all will be used? The extra bits extend downwards, so for identical exposures you should always get 2 more bits of DR ...

K7 owners- a few questions?
I know this is easeir said than done, but I would most strongly recommend going for the K-5. I have owned the K10D, the K20D and now have both the K-7 and K-5. As you can see from this awlful confession, I had wasted a packet of cash in the process. I was very happy with the K10D at the time, b...

K-5 battery recommendations
I use the shortest review time, but tend not to use flash. I do use playback to view images, but at the end of a session or a set of images within a session. I don't consciously try to save battery power and in fact have the auto shutdown switched off. It never ocurred to me before reading this thre...

Pentax 17mm fish eye (non AF) lens on DSLR cameras
Yes you can but will lose some of the fisheye effect due to the crop sensor of APS-C format. I assume it's the K 17/4 in which case you will need to set exposure manually. John

Pentax 17mm fish eye (non AF) lens on DSLR cameras
Thanks so much for your quick reply. It is an Asahi Pentax 17mm fish eye manual lens working at f/4 and also has it's inbuilt neutral, yellow and orange filters. I guess since the Pentax DSLR cameras will not have a full frame sensor it may crop the fish eye effect and the exposure will have to be g...

Raw v Jpeg
I've said it before, but shooting at least one slide film is an excellent learning tool for any photographer. You then see exactly what you've shot and all the defects in composition and exposure are laid bare. If a photographer can get a good success rate with colour slides, then digital is no p...

I agree with the blow out highlights, that simply means your information is lost. A sensor however is more like a linear device, so at the lowest darkest parts the "steps" it can record are very small but the number of "steps" increase when the exposure/brightness increase as well so that maximum n...

K-5 Metering
The metering has completely changed from the K20D to K-5 and I still don't know if its for the best. The K20D will always if left to its own devices underexpose wheras the K-5 will almost like a petulant child blow a highlight somewhere just to make sure you're paying attention :) The K-5 has 77 se...

programable remote timers
Hi Ian, I have one of these from ebay, looks the same though. Easy enough to program, I used it once or twice with my K100d. It worked as expected, the K100 did not. Forced Dark Frame Subtraction for longer exposures will leave gaps in your trails, and the noise was awful, it got more and more hot p...

What do I lose if I trade in my K10?
I doubt you get much for the K10D... I at least will keep it if i get another camera because the K10D is the last camera with a CCD sensor you never know where it's good for :) Also it's always handy to have a spare.

Just received K5 - initial impressions
Having just received my new K5 today my first impressions are: High Iso is way ahead of K20D - ISO6400 is probably equivalent to old ISO1600 Shutter noise is greatly reduced - definitely a good thing Body wise I must admit I find the K20D more comfortable, especially the R/H grip Ele...

Just received K5 - initial impressions
Agree with your comments about the grip, I find my little finger just slips off the bottom, I agree with this but must say I think I would rather part with my little finger than with my K5. I would also say it is not the extra stops with the ISO it is the better quality of image you get at high ISO...

Returned K5 - Where to now?
I have had sensor stained K5's and they have been replaced without cost to myself by SRS. I echo similar advice - buy a K5 from SRS.

Returned K5 - Where to now?
I think you were very unlucky :( I'd honestly discuss this with someone like Chris at SRS. Many of our members buy all their new stuff from him [ I do for one except for my camera which was got in the USA ]. I've found him extremely helpful [ and so are all his staff :) ] and willing to go t...

Returned K5 - Where to now?
Hard to tell from the small images, but it looks like it is focussed very slightly beyond the intended subject. In the first one that might be due to the centre AF sensor picking up the wood grain at the centre of the frame rather than the subject just below centre. In the second one it looks in...

Returned K5 - Where to now?
The K-5 has a problem with purple fringing and this can be seen in the first shot. I was surprised when I saw this on some shots I've taken. I hope they can fix that with a firmware update :x PF comes from the optics of the lens or maybe the microlenses on the sensor so nothing that can be done with...
