K10D and Twilight football
I'm really pleased that I choose the K10D for my first DSLR. I'm hoping that some more experienced users might be able to help me to get even more from the camera with regards to shooting amatuer football (from the touchline) in very low light. I normally use TAv mode so that I can control both sh...

also wonder if the camera's sensitivity can be pushed even more or will noise become just too intrusive if I underexpose and shoot in RAW mode? You can do that to some extent without it looking terrible. It helps to reduce the "colour noise" in post processing to make the noise look more like film ...

There are a few Sigma 70 - 200 f2.8 EX lenses on eBay as they have brought out a newer version that focuses down to 1 meter (the older one is 1.5 Meter) so some owners are upgrading. I got mine for just under £300.00 last month. Superb image and build quality, and being rear focus it focuses in the ...

I'm thinking you need some faster glass and you say your happy enough with manual focus. Then have a look at some of the older Pentax lenses (primes tend to be faster) that are about on well known auction site. Here a your money could buy one or two good lenses. 8)

Older manual lenses sound like a way forward at the sort of price which is logical for a relatively infrequent problem. Please excuse my ignorance but can I really use any Pentax bayonet fit on my K10D body? Will the lens F stop be adjustable? (tho in TAv mode I could see me wanting it wide open ...

Pentax A lenses (which have the all important 'A' position on the aperture ring) can be used in any mode, everything, except of course focus, is still automatic. Pentax M and M42 lenses (with an adapter) you will have to use stop down metering. I tend to use Manual mode, set focus with the lens w...

I find the green button works pretty well Pete, particularly when I use my BPM bellows which of course has to be in manual mode. All metering systems average the scene to a mid grey (18% grey in film terms) so the ubiquitous white cat in snow will alway be underexposed and the equally ubiquitous ...

This is proving truly most enlightening. DoF and manual focussing was the way back when we had to pay for every roll of film. We tried to make every shot count and I guess accepted that there would be a lot that simply "got away". My wishes for sports photos are that I capture the expressions...

K10D and Twilight football
Rataegeoff, I cover a lot sports events and music gigs, I only use fast primes (hence your comment about focus & zoom doesn’t apply here, life’s a little easier) and I’m always on manual focus (even prefocused) because I like the degree of control I have with that. Some autofocus systems can be f...

The camera won't try to focus on rain drops in front of the subject, but rain reduces light and contrast generally, then AF doesn't always work so well. I'm sure you will eventually (or even straight away!) get some great results with any fast lens - however manual or automatic it may be.

Thanks for the comments and guidance. I've now got an adaptor ring (Pentax...and great service from SRS)and had the chance to find out just how much more light an F1.8 lens lets through compared to a 4.0-5.6! This will prove fabtastic for portraits and close action shots. My telephoto option ...

Manual Focusing tips
Hi all, I have a K20d and Da*16-50. I tried a bit of manual focussing and was wondering whether the camera detects when the subject is in focus on all manual lenses. It seems to beep and thered focus box highlights when you get the centre of the frame in focus. Would this also happen on a full...

Manual Focusing tips
The body will give you focus confirmation with any lens auto focus or not. With the old manual lenses (M42;"K";M;and A series)many people have found this a help. Further if you use the camera in auto-focus single mode the shutter wont fire until the focus confirmation is present. This is called focu...

That just tells you which of the 11 focus points the camera's using. Dan

It would have been quite useful if they could have got the 11 red points showing up in manual focus rather than just the centre point though. I can't understand why that isn't possible.

Manual Focusing tips
There wouldn't be much point in that, would there? Surely it would save having to focus then recompose if I could just focus using say the right hand (top if doing a portrait shot)red dot and get focus confirmation. When I focus on an object I very rarely want it dead centre.

That is exactly my point. In the Rec. Mode menu, if you select the manual option in the Select AF Point, you can use the four-way selector to pick your focus point. Then you adjust focus manually until the image appears sharp, or the green hexagon lights up. Just note that the red dot just confir...

If all 11 points were lit, you would not have any idea where the camera is measuring. Yes I realise that thanks, I was talking about 1 point lit at any one time, which you can do with a AF lens set to manual focus but not with a manual focus lens in MF setting. Perhaps I should of made myself c...

Sorry, Mike, didn't realise that manual lenses only use the centre spot :oops:. I tested an automatic lens in manual focus. Now I checked my 1.7/50mm manual lens, and centre spot only, unfortunately. So I agree wholeheartedly with your initial comment.
