I had the same problem trying to photograph the aurora about two years ago and found that switching off slow shutter speed noise reduction solved the problem just as Jonathan-Mac suggests.

Hello Dave
I may have missunderstood what you are trying to do but altho' I do not have a CCS holster, I have for some years used a Lowepro Topload which I hang round my neck and secure the holster from swinging around by passing the waist strap of my rucksac through the loop at the back of the holster. Works well as the camera is easily available helped by the Topload opening away from you.
Also you can put the camera strap round your neck with the camera stored in the holster part for virtually instant use.
Have to be careful taking off the rucksac tho'!

Thanks again - sorry about delayed response but had an unexpected few days in hospital.

I think I shall go for the 2.4AL and see how it goes.

Thanks for the replies and advice. I should have said that the lens is for digital use on a K7.

It would seem that the sensible choice is between the 35mm Limited and the DA 35 2.4.

I have to make up my mind!

Thanks again.

I am looking to buy a 35mm prime lens and in the course of my searches I have read of the 'legendary' 35mm f2 FA lens.Is this the same lans as advertised at present by Amazon and others and if so is it as good as it's cracked up to be?
Thanks

I may be wrong but my understabing is that the preview image is an embeded .jpg which presumably is affected by image mode settings.

Thanks very much for your help - I'll try switching off the NR next time. I did wonder about black frame but didn't think it would extend the processing time for so long. I presume that the other camera users around me didn't have this system or it was turned off.
Thanks again.

Hello
I recently went on a aurora viewing/photographing holiday. I was using a K7, Sigma 10-20 at f4, iso 800-1600 and exposures ranging from 15 - 90secs,cat 6 card and freshly charged batteries.
While my results were encouraging I found that my camera took about the same time as the exposure to process the results and produce an image on the screen. I was using DNG but there was no change using jpegs and the file sizes were about the same as daylight images which appear quickly.
This performance was in marked contrast to the surrounding Nik/Can users and caused a few missed images. Although the temp was about -2 and there was some wind it was not extremely cold.
I wonder if anyone can explain this to me.

I recently bought 18-135 from SRS and it came unboxed. I queried this with them and was informed the lens came from a split kit. I was reassured that as long as I kept the dated receipt from SRS the warranty would be ok.
I haven't done any specific tests on the lens but it seems quite adequate for my purposes ie walkabout and occassional prints up to A4.

Hi, I've been reading and learning from this forum for some time but felt that I should join. I've been a Pentax user (hate the word Pentaxian) since K2 days but changed to digital with a *istDS initially and K7 since last Xmas.
