Originally posted by rscoote For journalistic sports images I don't think it makes too much difference and is certainly better than a camera that cannot focus. When I posted these pictures on the UK Pentax forum people actually liked the gritty, grainy effect.
Yes, not every shot needs to be printable quality. Most end up on the internet at quite small image sizes.
1/800s, f/2.8, ISO6400 and then pushed another stop in PP. Most of us have been there: desperation! The images from an APS-C with those settings are not going to be pretty. The images from a FF will be about 1.2 stops better if you are prepared to accept a narrower DOF (not that desirable when you're interested in a group interaction). At least you've captured some drama, and conveyed some emotion, and that's about all you can hope for under these conditions.
I won't bother trying your K-5 under this lighting. Including the 1 stop boost in PP, I calculate that this was an LV 5.6 situation. I think the K-5 will focus erratically and slowly under those conditions.
