I am short sighted and have not found this to hinder my photography.
Do you have trouble looking through
Do you prefer contacts over glasses?
If find that glasses make it harder to get my eye up to the viewfinder, while it is possible to shoot with glasses (either pressing my glasses up to the viewfinder or using the dioptre adjustment on my Canon SLRs) I much prefer wearing contact lenses when using my SLRs, as it allows me to get my eye up to the viewfinder without worrying about the dipotre settings dial having been nudged.
When using compact cameras where there is a screen instead of a viewfinder, either glasses on contacts are fine. I have not used an SLR with "Live View", I imagine this would be the same as a compact.
Do you find it harder to manually
Do you have a special viewfinder? (I
think I have seen things online that
are the equivalent of a prescription
As mentionned above I find that a split focus screen greatly aids manual focus, brighter focus screens are also available, they also help manual focussing, but still allow you to see the whole frame.
On a slightly different note, my father is longsighted, his biggest difficulty is that he can focus fine with out his glasses, but he needs to wear his glasses to see the controls on his camera, so is constantly taking them on/off.
