Thanks Shashin. I am looking for a 28 (or 25) to fill the gap between 21 and 35.
I do a lot of landscape shooting and semi-precise framing is often required for the type of work I do. I have done a lot of stitched pano's but I would rather take a single shot and save me the extra processing time and effort.
Gary, Gary, Gary-This sounds like the atypical symptom of GAS.
I can understand your wanting a lens to "do it right", but in the end what do people look at-the entire image/scene and most do not care if it had been stitched or a single shot.
Believe me most of us could save TONS of money if we just stitched images more often than carrying around $5-10k or more in WA lenses for that "get it in one frame" shot. In the long run PS is cheaper even though we allude ourselves into thinking that Leica glass might cost us nearly nothing by the time we are ready to sell it. Time for stitching is 5 minutes and it saves you $3k or more by using it and if you PP your shots you know what's another 5 minutes to get it really right. Anyway many landscape pros stitch with vertical WA shots which gives both foreground and background in each image so with that approach no WA lens will cover the entire scene anyway.
Look at all the money tied up in glass-it's GAS!
