How would you improve your Pentax SLR?

Okay I have the K20D so the following:- Magnesium body version of the K20D (prefer the grip of the K20D to the K-7) Non-crippled K mount Faster SDM (lets nick it from Canon) K-7 shutter 51point AF and AF speed from Nikon 100% viewfinder FF sensor from the 5D MK2 Cropped ability for DA lens...

How would you improve your Pentax SLR?

Mine's a k20d. It's an excellent camera and it will be a long time before i feel the need to upgrade. The wish list: in camera neutral density graduated filters would be terrific b&w filter setting that stays on for multiple frames full frame sensor TTL flash compatibility non-crippled KAF2...

How would you improve your Pentax SLR?

Maybe it's just me, but unless Pentax starts to make terrible cameras that are too far behind the other brands to even consider, I'll be staying put. My "old" K100D Super does everything I need it to, and it'll be quite some time before I've outgrown its capabilities. Some changes would be good, how...

How would you improve your Pentax SLR?

A sensor measuring 36x24mm, of course!. A threaded shutter button. The ability to shoot in b&w. I know this can be done, but it involves pushing buttons in the menu and a lot of faffing about. My Canon A70 compact is always set to b&w. Conversion after the shot is a bit of a pain. I like to see the ...

Sensor shake on KX

A number of cameras shake the sensor (or is it the mirror) on start up to reduce dust collection. On the KX this is an optional setting. I an wondering if it is best to set it always to vibrate on start up or not? I have not done so at the moment because a) slightly delays start up time b) not su...

Sensor shake on KX

Yep, set it to shake the sensor every time. Don't forget to turn the camera off before changing lenses, this removes the possibility of anything going wrong with the electronics during the change (unlikely) but also cleans the sensor after the exposure to crud during the lens change. Ian.

Sensor shake on KX

.... that's not the reason you should turn the cam off during a lens change. The real reason is that the sensor is statically charged when the cam is on and will therefore attract dust. Ergo, turn the camera off. Bret

Sensor shake on KX

Nope, that is not the reason. There might be some static charging of the sensor but it will be shielded by the shutter. I'm with Ian in thinking it is to protect the electronics during the lens change. Lenses and the camera bajonet have electronic contacts that might be shortened in a way not too h...

Sensor shake on KX

Interesting. I can't remember where I read the static thing. I do it anyway, but don't see why the contacts can't be protected... Bret

Sensor shake on KX

I set mine to clean the sensor every time. I also make sure that I turn the camera off before changing lenses and always hold the camera facing downwards while doing so. As a result I don't have much trouble with dust - a good thing as the cost of an Arctic Butterfly cleaning tool scares me! :lol:

Sensor shake on KX

I rarely turn the cam off or shake the sensor ! and no problems :) .

Sensor shake on KX

Thanks for the comments. Never thought about switching off during lens change but will do this now - unless in the inevitable rush to get the picture.. :D

Sensor shake on KX

I don't have sensor shake on startup to have the camera ready for use sooner. It's never removed a speck of dust in my cameras anyway.

K100D with Vivitar 28 - 210mm lens

Cannot speak to the K10 I started with a DSLR with a K100 Super (keeping my MZ50) and changed to the K200D when I saw a new one at a very good price. As most folk here will tell you, any Pentax DSLR will take any Pentax fit lens. If your Vivitar lens is screw-drive autofocus, you can put it on th...

K100D with Vivitar 28 - 210mm lens

Hi Dunc and welcome to the forum, Either camera would allow you to take excellent photographs. I have a K100D (my only DSLR) and I love using it with old lenses like the one you own. BUT if you can afford it, the K10 is superior in every way. I've seen some lovely detailed, noiseless images in...

Why?

I really think that dropping the K-m was a mistake. Ok, maybe Sony had discontinued the sensor but surely Pentax could have considered something like fitting the K-x sensor to keep it in production? The K-x would still sell on the basis of being better specified and having video mode, the K-m would ...

Posted by Dangermouse on 08/03/2010 - 23:53

Why?

Don't forgot the time between the models, the D80 is just as old as the K10D and that isn't produce any longer either. Also they upgraded a lot of hardware but it looks like the K-X and the K-7 shares a lot of the same components to save cost, if they also need to produce the K-M, K20D and the k200...

645D lost the competition

Same pixel count and same image sensor size as the newly announced Mamiya MF digital. But Mamiya has 16 bit color and penatx only has 14 bit (here are the Pentax 645D specification: http://www.infoborder.com/Digital_Cameras/Pentax/645d.php ). How did pentax lose 2 bits of color if the image sensor ...

645D lost the competition

I can't see that 16 vs 14 bit makes much difference. They use a different sensor in the Pentax to the Mamiya. http://www.pentax.jp/english/news/2010/201008.html for all the official details of the 645D.
