Is it possible to change the direction of the control dials (e-dials) on a K20D?

Somehow they just go the wrong way for me. I use them for aperture & ISO (AV), shutter speed & ISO (TV) and shutter speed & aperture (M). Whenever I want to increase or decrease a setting, somehow my thumb/finger turns the dial in the wrong direction. So can I reverse the direction of adjustment of the two dials?

Which 20/21mm - Pentax or Voigtlander?

Any comments on the relative merits of these three lenses?
- Pentax DA 21mm f3.2
- Voigtlander Color Skopar 20mm f3.5 Aspherical SL II
- Pentax A 20mm f2.8
- Pentax M 20mm f4

I prefer fixed length to zoom lenses, am very happy to focus manually and value small & light lenses.

I will mainly be using the lens for architecture. Main camera is a K20d, but I do occasionally use my film bodies (which I know rules out the DA 21mm).

Which one would you recommend and why?

Thanks,

Samsung NX10 discussion

Tried a NX10 in store yesterday.

It sits nicely in the hands, its sufficiently smaller and lighter than your average APS-C dSLR to notice the difference, the ergonomics seem OK, but then, you look through the viewfinder. Awful. The image seems fuzzy at best when the camera is still and when you pan the "colour tearing" is just dreadful. Accurate manual focus is next to impossible with the EVF, the resolution is just not up to it.

Psychologically I'd find it very hard to have faith that the dreadful image in the viewfinder will result in a beautifully detailed detailed 14 MP DNG. Its just not a camera I can imagine loving.

I really wanted to like this camera. My GX20 is great, but just too large and too heavy. The live histogram in the NX10's viewfinder is a real step forward, but there is no way I trade the (only relatively good) GX20 viewfinder for the NX10 viewfinder. To quote Sean Reid "The finder, after all, is central to seeing the subject and seeing the subject is at the heart of our work as photographers.".

Please could you tell me which lens/es are included with the Lensbaby?

Standard Double Glass, Single Glass, Plastic or Pinhole/Zoneplate?

In the UK when bought new they come with the Double Glass as standard, whilst the other three lenses are extras.

Price of postage to the UK?

Thanks

GX20 as backup for K20D

Raw support for GX20 DNG format was added for iPhoto (and Aperture) in the second half of 2008. Download the latest camera raw compatibility update to get it: - Apple - Downloads - Application Updates - Digital Camera RAW Compatibility Update 2.5

Note, for Apple products, camera support comes as part of the operating system, rather than as part of the application program, so you need to keep the O/S up to date for new cameras to be supported.

Jupiter-9 85mm f2 M42 - Is mine typical?
Posted By FreddyFrog

This was my first thread on this forum and I've been really pleased by the helpfulness of your replies - thank you.

In summary:

Metering - I'm pleased to hear that the erratic metering is not a fault with the lens, less pleased to hear that its a general problem with the K/GX line of dSLRs. Interested to hear that changing the standard focussing screen may help. I've been considering a Nikon K-3 screen from FocussingScreen.com as replacement for the standard screen in my GX20. Any views on whether this screen might improve metering?

Av mode - yes this is much easier than Manual mode - thank you for pointing this out

Yellow tinge - seems to be a normal characteristic. This gives a quite distinct colour shift to the images and is the one thing that makes me unhappy with the Jupiter. Any views on how should I deal with this? Should I, for example, fit a coloured filter permanently to the lens, manually adjust the colour balance at the time of shooting (I have a WhiBal card) or adjust the colour post-process?

.......... and can I really get rid of the yellow tinge by shining UV light through it? Is this a permanent or temporary cure?

I've just picked up a Jupiter-9 85mm f2 M42 lens, serial number starts N73.... and wondered if my experiences with it are typical of the lens:

1. The lens has a slight yellow tinge to it. Should I add a coloured filter, adjust the colour post-process or ditch the lens?

2. Metering on GX20 using Manual mode and the Green Button is accurate from f2 to f5.6, but overexposure creeps in from f8 onwards, by f16 the metering is way off. The over exposure is more pronounced using matrix mode than when using spot or centre weighted modes. Apart from test shots and using the histogram, is there any way to ensure more accurate TTL metering?
(On second thoughts, is this a problem with this lens or manual metering problem with all lenses? - This is the only lens that I use manual metering with.)

3. Soft at f2 and f2,8, sharp from f4

4. Bokeh gorgeous - which makes me want to persevere with this lens, but the metering problem is putting me off using it.

Any comments?
