Image sharpness - focus
I believe that there was a problem with the projector that was used, even the judges later in the evening asked for it to be re-focused. Please have a look that these images and add your comments. Many thanks

Greetings Michael: At least on my monitor it appears there are elements of softness in each shot you posted here except the first one of the race cars. IMO, that one is just a bit underexposed by perhaps 1/3 or even 1/2 a stop. The light reflecting off the softness of the feathers of the birds may give the illusion that the shot isn't tack sharp but it doesn't appear to be like a depth of field problem because the eyes and beaks are in focus and the rest of the bird(s) seem to be in the same plane of focus. As to the elephant (or is it someone with a bad skin condition

I concur with Mark, Michael. Though BP displaying them at 720x480 doesn't make it easy to see.

Although you need a little sharpening because of the high pass filter in a digital camera, those pictures look like you used a lens/extender combination that isn't of a great quality. Did you use an extender? Maybe with a zoom lens?

Thanks for all of the comments that have come through thus far, please keep them coming. If I can as one thing though, can you also include you suggestions on what I could have done differently to make these and any future images that I take better. As for the lenses that I was using. I have recently bought the Canon 100-400mm L series, the first and last image was taken with that one. The other 3 were taken with a Sigma 70-300mm. Once again - many thanks. Mike

Have you used your software program to sharpen them up? I hope you don't mind but I've taken the liberty to apply a sharpening technique to one of your photos. When viewed side by side, you can see the difference.

A sigma 70-300 probably is going to be just like a canon 70-300. A pretty good lens, not the best, but where it shows it's not the best is at the 300 mark. The 100-400 has been touted as a sharp lens around here. So with all that being said, one thing is use the basic sharpening that you need with digital. Not a lot, just a little. Any cropping done to the birds? Plus maybe hand holding the the Canon lens, since it would be heavier than the sigma. Anything shown on betterphoto needs extra sharpening, more than you would for viewing or printing. Just the way they end up on this site. But I think your main remedy is to use some sharpening. And maybe that canon lens isn't at it's greatest at the 400 mark. Because zooms are a compromise compared to fixed focal length lens.
