venus and moon
I think it is also worth pointing out that camera shake is a problem at these distances. I try to get round this by using the 2 second delay which does a mirror-up at the start of the sequence. I have also been told that hanging a large weight underneath helps to dampen the tripod but I have no...

venus and moon
I was desperate to try out a newly acquired Sigma 600mm mirror lens. http://i172.photobucket.com/albums/w20/GlynM/Moon%20shots/IMGP1610-c1.jpg The lens is fixed f8 and the camera was set to an ISO of 200 and an exposure of 1/20. I'd be interested in your experiences with this lens. I've jus...

venus and moon
I'd be interested in your experiences with this lens. I've just acquired one as well, and overall I'm quite disappointed with it... I have to agree with all your comments. Taking pictures of the moon is about the only thing I have felt happy with it and even then getting a good focus takes a lot ...

lens compatability
I want to buy a secondhand 50mm fast lens for the K10D, have seen one locally : SMC Pentax-A 50mm F1.7 lens , what would the compatability be with my camera, I am not sure about 'A' lenses. Obviously it wd be manual focus, but what about exposure, etc..? compared to my existing lenses FA's which...

Another Portrait up for your views
Hi I took this image of my girlfriends sisters daughter. It was took with the K10D and I used the Pentax F 50mm 1.7 at F 4.5 with no reflector using natural lighting. Only thing I do not like was the top right tree edge it distacts me as it seems out of focus compared with the other part of the t...

Comments welcome I think it's your best portrait so far, by a HUGE margin. I don't think the out-of-focus part of the tree distracts at all; if anything, it keeps attention on the subject. I agree with you that the hand is important to keep in the frame.

I agree.. the last colour image is the one. Well done. I don't agree. I think people are being fooled into thinking that it's better because the subject is slightly sharper. However, the bright green background on the left, and the large expanse of out-of-focus tree on the right, in my view a...

If you got to this in 5 months then I can't wait to see what you throw at us in about a year... For time is the biggest problem to get my skills better. It takes trial and error and you have to take your time for it. I hope that during the next summer holiday I can take more time to do some exper...

Interesting comments guys Changing the subject slightly as anyone tried this experiment when you open an image in say windows viewer it looks OK then click on the little icon at the bottom that expands the image to full size, then click on the little icon that then puts it back down to the origin...

K10D or.......
... if it were uncoated then it would pass only ~66% of the light compared to 98% with SMC. Can you substantiate this in any (non-technical) way? To me, a coating is simply an additional layer, multi-coating being more than one additional layer, that would actually attenuate the lens's ability t...

K10D or.......
I saw only the Pentax and Samsung versions of the 18-55mm kit lenses, not the 50-200mm. My opinion, apart from the rubber focus/zoom grips and name labels, they seemed identical to me. Curry's online price may be £29.87, but they offer only reserve & collect, and guess what . . . none of the st...

2 movement images help choosing Please !
You're among friends, here, Pete. To what extent is it real, and to what extent is it fake? I won't grass you up... promise. Chris believe it or not this is 100% as it was took. God knows how it turned out like this. All I used was a tourch and an exposure of 10 seconds in a dark room and a delaye...

K10D manual on ebay
Seem to remember a few posts a while back from people wanting an English version of the K10D manual. Well, I have one on ebay at the moment: currently at 99p with no bids :( Also an M 50mm f1.4, M 28mm 2.8 and rear converter K T6-2X in my other items if you're interested. Steve

Lens Fit Problem
I had a old PKA zoom that wouldnt fit, as you describe turned so far but no further, turns out one of the flanges was bent in towards the lens just a tiny bit, scarcely visible. Don on this forum suggested that might be the problem and it was. i bent it back and the lens fit fine. it wasnt too...

Views on Sigma 70-300 APO DG
I got the Sigma 70-300 APO DG a while back. It is sharp enough in my book at 300, although I usually do a CA correction in SilkyPix. Here's one example that I took out of my bedroom window: *istD, Sigma 70-300 mm F4-5.6 APO DG Macro, 1/350 s, A11, ISO 200. I'm sure I have more examples taken a...

What happens when battery in grip runs out?
I've found the same problem as amoringello using the same set-up and for all the same reasons. The grip battery is easier to change... Not sure that there's any solution other than using the auto battery selection but then you could end up changing the wrong battery. I prefer to know which one is fl...

What happens when battery in grip runs out?
George / John - the grip I find aids the handling a great deal. My main lens on the K10D is a pretty hefty Sigma 24-70 f/2.8 and having the extra weight at the back helps to balance things up. Exactly. When the flash is mounted on the hot shoe, the camera is always flipping over when I hang it aro...

What happens when battery in grip runs out?
I'd agree with both sentiments re the battery grip. First I find the handling superb with the grip attached and couldn't imagine going back to not having it there. I also have the same battery power management issues that has been reported above though and the suggestion of using just one battery...

Buying from Hong Kong Advice
I know someone here in Holland who regularly buys from Hong Kong. He has a regular contact there, who is well known in Dutch photographic circles. To overcome import duties and VAT things are sent via DHL and labelled as repairs. Just once was he phoned up by customs about a lens and he said yes it ...
