Cashback and voucher !
When my Pentax camera arrives, the cash-back form which I have gives a choice of how you want the cash, I ticked a cheque. No mention of a voucher, cash-back means cash not a voucher surely. Hi Morelia, I said that the voucher arrived through the post, it's not part of the casback offers, but it c...

K10d and Sandisk SD card problem
WE had some Jessops SD cards that would not fir properly and they were definitely thicker than normal. They went straight back for exchange because all that particular batch were too thick. I'm sure other manufacturing defects happen, and of course fake cards are made by people who don't care abo...

K10d and Sandisk SD card problem
Personally I would never buy another Sandisk SD card. I first had problems with their standard 1GB SD Cards not working in a Pure Evoke-3 DAB Radio I tried 3 of them. Someone on alt.radio.digital also said he had problems with Sandisk, but no problems with Toshiba cards so I bought some (1gb Std. sp...

K10d and Sandisk SD card problem
Got the camera back without the repair as I requested. It works fine with the 8Gb SD cards I have so I'm going to live with it as I was going to replace the camera this year anyway. Very disappointed with the service as I did ask Pentax to give me a statement about the card etc so I could pursue San...

Advice please
I use the 10mp K10D, but take most shots at 6mp, mainly to save hard disk space. (I take a lot of photographs!) I notice little difference between 6mp and 10mp for normal family or hobby shots on the computer screen or in an A4 print, although if someone asked me to photograph their wedding, for exa...

Anyone got a K-m?
The only deal breaker spec I've seen on the K-m which seems to have gone largely unmentioned is it has no DoF preview, other than that it seems to be a fine camera. DOF preview can be achieved with old manual k mount lenses by selecting the aperture, pressing the lens release button with a finger of...

bulb mode on the K20d...
I bought a cheap Chinese cable release off ebay to experiment with. It is a bit plasticky & wouldn't take much abuse, but it has 2 stage button (same as shutter half press) & a manual lock off for use with bulb or even focus trap if you're a twitcher. Great if you don't think it'll get much use. ...

18-55 kit lens - mk1 v mk2
I'm liking the quality of the 18-55 Mk1, but I dislike the stiff 'jerky' operation of the zoom ring. Have I just got a dog or are they all like that? It would possibly be fair to add that I tend to judge lens handling by all my old metal lenses that are smooth and gorgeous by comparison. Yes, gorgeo...

18-55 kit lens - mk1 v mk2
K20D, because it could reveal more detail, and preferably with manual focus to eliminate any AF issues.

18-55 kit lens - mk1 v mk2
Here's a comparison between a mk1 and the Sigma 10-20mm. Both at f/8 and zoomed to 20mm (confirmed by Exif data) both are centre of frame. Available light so low contrast. 100% Crops Enlarge to see diff clearer. Unmodified Jpegs. Quite clearly the mk1 is better than the Sigma. Is it a g...

18-55 kit lens - mk1 v mk2
It's possible that the Sigma lens isn't focused accurately. Select the best from several different manual focus attempts to eliminate focus problems. This is how all lens tests should be done, unless you're just testing the focusing. I thought that the mark1 was renowned for being very good (f...

It's possible that the Sigma lens isn't focused accurately. Select the best from several different manual focus attempts to eliminate focus problems. I did think that which is why i'm going to do further tests. I did use manual focus and used a 2x Pentax refconverter, but the Sigma is a difficult ...

Samsung Pentax lens advice please
I saw a review of the Tokina 12-24mm zoom. Is this just a variant of the Pentax lens? The 'change to manual focus' is different (pull the focusing ring towards you) but it is an constant F4. No cheaper than the Pentax one though. Cheers, Kris.

Infra-red on the K20D
Personally I find that the longer exposures add to the surrealism of the IR's. I found getting the exposure right the 1st few times the hardest. I thought it was bright enough but you really have to push it till you start seeing whites or close to atleast. back yard testing is good for that. ...

Unprocessed RAW v JPEG print test
Here's a demo. Four versions of the same image. All 100% crops. The JPEGs are from the K10D (set to medium sharp) with no post processing (apart from cropping). The differences between the camera's Bright and Natural settings are most interesting, I think. (Actually this was shot as a RAW only, b...

Unprocessed RAW v JPEG print test
I'm generally happy with Silkypix's sharpening. Despite not offering selective sharpening, it's actually very sophisticated and good, so I don't want to shove the output through another program if I can avoid it. (The example picture I posted in this thread isn't my best effort with the program). ...

Link AF Point and AE - DOH!!
[ramble]I'm trying to rest up a lot to get over what ever it is that's bugging my health at the moment, and decide to have a casual look over my Pentax gear. While playing around and switching between the 18-55 and 17-70 and metering against a table lamp I came across this startling realisation...[/...

Link AF Point and AE - DOH!!
The way I understand it is that while the camera is set to matrix metering, if link AF & AE is enabled the camera will in effect work in a similar way to centre weighted, ie; normally the centre portion of the image will expose brighter, but with AF & AE linked this will be linked to the focus point...
