Lens calibration - Focus Tune software

Very interesting, it has something in common the way it works with Imatest, used by EPZ and others for lens testing. That should do the trick very nicely and produce better results more easily than what we have been doing up to now. It's worth noting that spurious values do appear and that's ...

Lens calibration - Focus Tune software

You mean you don't already? I often do a 3-shot bracket as I rarely find the metering system gives me the ideal exposure. Don't get me wrong. It's a great camara, apart from focus, exposure, ...!

Lens calibration - Focus Tune software

It's not metering that I may shoot more than one shot for, but I might if the shutter speed is slow, even when using SR. Usually some shots will be sharper than the rest.

Lens calibration - Focus Tune software

Sounds like a focussing issue with that particular lens, so I doubt it. A K-3 may even make the problem seem worse if you pixel peep. I must admit I've never understood why autofocus accuracy varies between lenses, even less why with a zoom lens the micro AF adjustment should vary with focal lengt...

Non genuine batteries

Just a quick question about the cheap replacement/extra batteries. Two batteries came with my secondhand K-30, one original Pentax battery and one Hama third party battery. I've always used the cheap batteries in the past myself, both with the K10D and Canon. Absolutely no problems. But my K30 is s...

Locked SDHC card

Thanks for the replies. Just to go through what i've done so far: Tried formatting with both cameras (the Panasonic as well) and the PC but no luck. Check the lock switch, its not in the locked position. Moved it up and down to be sure. Cards bought from Mymemory. Never had any problems wit...

Locked SDHC card

Go online and set-up a SanDisk account. Register the two cards on there with the Place and Date of Purchase. Also register any others. Then call SanDisk on Monday, tell them the problem and they will ask for you user name. They will be able to see the two cards - and that is enough f...

Locked SDHC card

Will contact MyMemory Tuesday and see what they say. As the cards only cost £29.28 for the pair, i doubt i'll send them back to Sandisk if the postage is too high. Hopefully MyMemory will be able to sort it.

Exif Data Codes

Karel - I'm using a Mac, and getting the exif data readings from that. But I've just run up my Windows virtual machine and installed ExifToolGUI, which gives a little more information. Very useful when you want to dig a little deeper. Using ExifTool I am getting the SR codes of 7 & 135, instead of...

Image misaligned in viewfinder - K30

Hi all. I've just bought a K30 with the 18-135 lens as my first DSLR. It's been working flawlessly, and I've been enjoying exploring the various buttons and dials :). Today, when taking a few snaps, I noticed that the resulting image seemed slightly different to what I had lined up in the vi...

K5ii or K5iis?

Want to upgrade my K7. I mostly do two types of photography with it: 1) landscape which is ISO 100, f8, tripod, and whatever shutter speed it sets. Sometimes I use an ND filter if there is moving water. Quite happy with these images. 2) cats in available light. Here I need to use a high IS...

New Limited Lenses on a *istDS?

Hello everyone. I have a *istDS, and am using a collection of older M42 and K Mount lenses. Reading reviews of the newer Limited lenses, I gather that their Auto Focus is achieved by a physical drive connection to the camera body. Is this connection the same as what was around in the olden ...

New Limited Lenses on a *istDS?

Although the 'olden days of 2004' are quite modern considering the screw drive goes back to the SFX from 1987 :)
