There are some fun ones there.

I have found a monopod invaluable. The data at the bottom is listing lens, but not focal length, but if you're using a 50-135, 1/25 is likely to be a bit slow for free hand holding. > I was still playing with the settings (various AF modes) and modes > (S/TA/T priority).

When using a long lens, you may find it even worth pushing to 8,000, or even up to 16,000 to get the shutter speed you need. Next time you are out, try varying the ISO up to ridiculously high levels. For future reference it'll be handy to know just how hard you can push it. I've lost more photos to too low a shutter speed, and even too little depth of field than to too much noise. > (Some NR, in the range 35-70 for luminance, was applied in LR, except > for the 2nd shot, _IR00019, where no NR was done.

I have been finding that my biggest challenge lately has been autofocus. As you mentioned in another post, one issue is with size of each focus point being too big, so you think that you're focusing on someone's face, and you are focusing on the striped shirt of the person three feet behind them. It's also difficult to see to manually focus in the dark. If the dancers are staying fairly stationary, you can try live view and manual focus, hit info a couple times to zoom in. I ran into a friend at a West Coast Swing dance last night (not my normal thing, but they were local and had a live band). He had just gotten a G5, and commented how difficult WCS is to photograph. I took that as a challenge. I also played a bit with his G5 and 20/1.7 lens. There are certainly things to like about a good EVF, and the G5 is nearly there. I haven't seen the images from his camera yet, but the sensor seems to still lag quite a bit behind the K5. On DxO mark, it comes in comparable to the K20. I was checking out a K30 review and it seems to have quite a few features that I really hope make it into the next generation of the high end APS (or FF) body. -- Larry Colen [email protected] sent from i4est -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
