Question from a member
Opticron do make an SLR adaptor (at least they did last time I looked, this year some time - here's a ) but your comments on aperture and stability are very true, often the working aperture is f/11, with an effective focal length of 680mm or similar. It all depends on the scope, the objective lens...

Red ring around moon
At 200mm you can go as long as 1 second for critical work At 200mm on a K10D, the angle of view is 6.87 degrees. A one second exposure is therefore 2.4 pixels of movement blur. If this is really good enough for 'critical work', then presumably 2.4 pixels is not significantly greater than the oth...

Red ring around moon
Here is a couple of pics of my first moon phto. I built the 400mm F5 lens. I admit to just missing perfect focus. But I didn't have a split screen in my DS yet. FOV would be like a 600mm in 35mm film.

Can someone tell me how to set up my K10 so that I can take shots where there's a lot of movement? My previous camera was a Canon, and this had an action setting that allowed me to take pictures of moving subjects. Unfortunately, the K10 seems to have no such facility and, if anything moves in t...

Thanks for the advice. As it happens, I do use continuous focusing, but this doesn't seem to overcome the camera's reluctance to fire unless and until it beeps to indicate that something has come into focus. I've also set to manual with continuous focusing, and still it demands that something come...

Then definitely there is a glitch there that I can't think what it is. With AF.C you should be able to release the shutter at anytime, even if the subject is out of focus. Check the menu, is there anything which says RELEASE SHUTTER ANYTIME or something like that? As far as I know everything in defa...

Firstly you will need to set the highest shutter speed that light conditions and the maximum aperture of the lens in use will allow, which is what the 'action program' on your previous camera would have done for you. So you need to select Tv mode. You have moved from an entry level camera to one whi...

It's a matter of practice as well as setting up the camera correctly for your individual purposes. It will also depend upon the actual lens used, as some focus quicker than others. To suggest an answer to your question it would also be helpful to know what sort of movement you were trying to capt...

Manual focus on the selector by the lens, and 'M' on the dial will take a shot no matter what the auto focus indicator thinks. As said previously, the 'Action' setting is an entry level feature, like you'd get on a P&S, that will automatically bias the exposure to a fast shutter priority. On a Pe...

I'm beginning to think that there may be a fault in my camera, as I had tried almost all the program settings suggested by you helpful chaps. Perhaps I'm doing something wrong, but I've yet to discover what. In AF the camera hunts frantically, irrespective of the program setting used. In MF, it j...

Have you manually tried to turn the lever to AF.S and then AF.C and then try to focus and release the shutter? May be the lever is stuck on AF.S. In MF, it just stalls until the red square appears in the viewfinder This is giving me the impression that perhaps you haven't understood properly how ...

Go to the Fn menu and then upwards to select the drive options. Is the camera set to the single shot mode? If it is set to 2 second delayed action this could explain your problems. The red square in the viewfinder does not indicate focus has been achieved by the way, only that the point indicated...

I guess you're having trouble as the AF system is hunting to find focus before finally firing... Try disabling the AF on half press of the shutter button & use the AF button instead this will help stop it hunting before firing, there is also a setting you need to enable where you can choose wheth...

This post is going to seem patronising, but reading the above either you are doing something wrong or there is a fault with your camera. I'm going to explain in words of one sylable so we can be absolutely sure you aren't doing anything wrong. Place the camera on the table in front of you, switch...

i haven't got a K10, but the K200 has a lot of the 10s bits and there is a setting in the custom menu which is called "catch in focus' or similar and that won't fire until there is something in focus. is the K10 2nd hand? it could be that setting is in use. saying that, the above post about tu...

I Think I know how the last link (image) was done If you look here is a shadow coming from the main light window and maybe some reflectors bouncing the light back as I don't see any flash high lights on the vase or table. James

Well I use Adobe Lightroom, so if you don't then itll be hard to explain But Under develop, you can alter the hue/sat/lightnesss values of each colour range, i altered the blues a bit to make the blue haze more purple, and fit in with the sky. I then selected the neutral density gradient tool (A r...

Something like this Andrew?? Used Gimp, but PSE with the addition of Grant's tools does the same. Copy background into new layer. Change blend mode to multiply at opacity 60 % Add layer mask and paint back everything in except the sky. (soft edged brush) Save to one layer-----> copy laye...

Best raw conversion software?
Peter, do you use this for PEF or DNG files please? When I try to open a PEF file the software crashes! John, as far as I know RawTherapee doesn't support PEF (I tried it myself a few months back), you would need to stick with DNG if you opt for RawTherapee.
