I thought it had a higher frame rate if you set it to APS crop? Out of my price range, so not speaking from experience...

I thought the 43 came from the diagonal of 36mm (x 24mm) film.

This makes sense on the face of it, but is at substantial risk of villagers (pentaxians) with pitchforks and burning torches if they do anything that slightly depletes the lens' magic. Remember the 15 limited upgrade and it's curved shutter blades ruining the starbursts! An improvement in sharpness or aberrations other characteristic might cause the loss of pixie dust and there would be riots in the streets.

Nope, you're right. Statistically, electronics or machines are most likely to fail when they're brand new. Also better for the environment to keep using old equipment. Even your car. Especially your car, actually! Better still, don't drive at all... ;)

Archiving antique maps and manuscripts

In an ideal world:
The DA35 Ltd would be the obvious choice for document copying, except that it's pretty expensive.

Alternative Plan A:
You may be able to find a vintage manual focus 50mm macro. Back in the day, macros were 1:2 magnification and f/4.
So, not impressive by today's standards, but more than adequate for copying documents. Manual focus is all you need for copying work, so that's money saved!
The Pentax-M 50mm f:4 1:2 Macro would be suitable, and probably readily available.

Alternative Plan B:
Would be to buy a modern 35 or 50 macro and then sell it when you're done. You 'might' get most of your money back! ;)

Other things to note
Shoot in RAW format so you can process the files to get the best image quality.
Shoot at 100 ISO.
Either use a remote or set the timer to the 12 second mode.
Shoot a grey card first to help get your white balance correct.

Happy Christmas

How to test Pentax 15-30 for decentering?

At this point, I would suggest you stop doing tests and just send it back. You won't ever be happy with it and if you keep it, it will only annoy you!

Round 2
OK, to me, it just looks like the foregrounds are out of focus because they're way, way in front of the focus plane. Like on the road shot, it's clear the focal point is on the road, about a 1/3 the way down from the center of the picture. Any closer than that will be getting out of focus.
Wide angle lenses don't have any greater depth of field than any other lens. Need to stop down even more if you want such a huge focal range. Try f/16, or try taking a similar shot where you focus on a very close object in the corner of the frame - I bet that will look sharp - because the brick wall shot seems to confirm that the lens is very sharp.

Looks like chromatic aberration because of the contrast of the sky behind the trees.
Also, maybe the shutter speed was too slow for the trees, which could be softening the look of things. Sounds stupid, but trees just won't keep still! ;-) Try starting at 1/250 and see how it goes.

DA 18-55 repair question
Posted By calsan
Replies: 9
Views: 391
I'd be amazed if someone here weren't willing to sell you an 18-55 for a very fair price... I think the assumption in the marketplace would be that an 18-55 isn't worth listing for sale as nearly everyone has two or three already! So it would be better to just do a wanted advert than risk your camera's mirror box with the possibility of that lens shedding parts. (Myself, I would just hold out for a 18-135, if you want a small convenient zoom lens... It's not much bigger.)

Nasty sensor accident, need cleaning / repair help

Replies: 36

It's worth pointing out that the K-10d manual, and indeed all digital Pentax manuals, has a section on cleaning the sensor. See pages 211-13

First thing in the cautions list is: "Do not use a spray type blower."
Then they list the cleaning Kit O-ICK1 as an optional accessory.

So, too late for the OP, but lesson learnt and lets hope others reading this in the future will read the manual.

What REALLY matters in computer hardware?

This doesn't matter. It were a car, driving everywhere at 100% means your engine is too small or your foot is too heavy..
But a computer isn't like a car, 100% just means the computer has allocated up to 100% of the processor to the task, because it's available. A faster processor with more cores will still get allocated up to 100%. If not, you would have to wait longer.

Yep. Same limiteds that I went for. They also work well as a three lens kit with my 18-135. This has become my travel setup.
The 35ltd requires a patient approach - not much good for point and shoot applications and if you don't pay attention to focus, you will miss. But take your time and the results are amazing.

Lens sounds most likely. Failing that, you could also try resetting the camera, in case you have inadvertently changed something...

I once called the police because someone had $20,000 of new computer equipment listed for sale in a local website for $800. The police told me if I thought it was such a bargain, I should buy it. I guess they were busy.

There world is awash with counterfeit memory cards, so that is a possible explanation also. Even buying from brick and mortar shops isn't a 100% guarantee.

Assuming a genuine card:
if you have erased the card in your computer, it would be a good idea to use sd card formatter then follow that up with a format in the camera.

I can't see magnetic being a problem with the flash. Wouldn't use on a computer though.

If you intend to do a bit more DIY repairs, pointed tweezers are very useful and I also I have a cool little three pronged thing called a 'pearl catcher tool' that is good at holding tiny screws or rescuing them when they fall inside impossible to reach areas.

My general camera/ computer repair tips:

Take a photo of EVERY step of dissembley. (Nothing that looks obvious when assembled is actually obvious when going back together!)
Use an egg carton to keep track of the order that you removed screws. Also stops them falling off your desk.

Pentax Genuine AF360 FGZ Flash Replacement Spare Repair Parts |

Good news, it's very cheap (when compared with most camera related things...)

I'm in two minds about the plastic shoe. It does mean that it's a weak part, but I think it's better that the plastic shoe breaks than if it were strong enough to snap the top off your camera.

(I've bought parts from US camera before without problems.)

Actually, it's default to .pef, but there is a menu option in the camera that you must have selected to set it to .dng.

Have you tried the pentax software that came with the camera? The advantage of this is I believe Pentax knows their cameras' image qualities better than third parties. You also get to have the same image processing options as in the camera and the software retains all your camera settings by default.
