OK so I have a 1D Series camera now. WOW it is awesome. Anyways. I am actually considering selling my Canon EFs 10-22 lens for a Sigma 12-24 lens because I would be able to use it on my 1D series camera. Now am I being stupid? I know that the Canon EFs 10-22 is probably the best UWA lens and I have absolutely no intention in selling my 20D probably ever and probably will buy its upgrade when it has one. So does this sound stupid to sell a great lens for a probabl lesser one?
Is there anyone with a 1D series and a Crop camera that keeps their 10-22 lens even though it can only be used on one camera?
