Value of a K20D
Not sure if this is the best place to put this question (admins feel free to move it to another area), but does anyone have an idea of the value of a K20D camera body (with or without a kit lens) The reason is, is that I have outgrown the K20D and need a second body to replace it as backup to my mi...

Value of a K20D
I'd still say 30,000 clicks OH....it's not the sensor but the shutter count.... as I say in my sale thread it's just run in..... I see 2/3 K20Ds on sale at the moment - and they don't seem to be moving - and now that K-7s are appearing at under £300 the trend seems likely downward - although sayi...

Faulty K5
Try cleaning the contacts on the mount, and just inside the mouth of the mount, with a dry, clean, lint free cloth. These contacts carry various information to the body. Could be a dirty contact might be the issue, and if it's not it's quick and trouble free to check.

DxOMark report on the K-5II.
hmm interesting that they find the sensor performs better than the mki and that the buffer holds more, looks like there are more improvements than Pentax let on...

DxOMark report on the K-5II.
The K-5 I and K-5 II also both score 82 at DXO and the sensor measurements show a very slight decrease in performance at higher ISOs for the MkII versus the MkI. No data for the K-5IIs yet though

DxOMark report on the K-5II.
There is bound to be some variation is noise from sensor to sensor even between sensors on the same wafer, and bigger variation between processing batches so a small change is not going to indicate anything significant. Also as with all semiconductors noise is very temperature dependent, getting w...

Plunge Taken...
Out of interest, with the two bodies now, have you thought about specifically how you might choose to use them, eg : any particular lens more suited to one, or any particular subjects you'd choose to shoot on one over the other? With the lower light AF on the K5 ii I'm thinking it might work better ...

how make IR photos with Pentax DSLRs
I was always of the belief that the in-built IR filter in a DSLR "opened up" the sensor's sensitivity range to allow it to "detect" IR wavelengths, and incorporate this additional information into the picture. Maybe I've got it wrong, or I haven't really explained it properly. I suppose the best ...

K30 vs K5
And the K-5 has a greater number of physical buttons, which reduces the need to take the camera away from the eye to scroll through menus when changing some of the more frequently used settings. And other niceties, like a rear facing IR sensor. By all accounts there's very little, if anything, t...

K30, focus peaking and manual focus lenses
Parcel Force did the business. It arrived around lunchtime - only 24 hours after placing the order with SRS online. Amazing.. A quick play reveals that I have a lot to learn. The K30 feels a lot lighter than the K200D. All the buttons are in different places too. The menus are not so hard t...

K10D decision
Coming late to this discussion. My K10 produces good quality images and I generally use it with manual lenses. As previously mentioned the old type sensor produces excellent smooth images up to iso 400. Regards

K10D decision
We're due a new chunky model I think (maybe with a FF sensor inside to justify the slight size increase!) The K10D is not massive, but being slightly larger means the buttons and switches are a bit easier to use. I always found the metering mode dial quite painful to use on the K7. I prefer t...

Anyone gone from K-5 to K-5II?
Thanks for posting the pics. :) They do indeed look identical in ISO quality, which corroborates with the DXO sensor tests published

How I arrived at my IIs
It all started with a Fuji s3500 really. Then I upgraded to a very nice s9500, wish I still had that one. I took the 9500 to Malta where it did all I asked, I loved the dual memory cards on it, save raw to one and jpeg to 'tuther un. A feature I think all decent cameras should have. When I got home ...

How I arrived at my IIs
If you'd like me help out in anyway John just ask Mate. I've tried to get it to show moiré and so far I've only had one instance, but I think pixel peeping at over 400% doesn't really count does it :) My next test for it is some macro work to see what detail it can really resolve. One thing I ...
