Hi there! I'm an amateur (very) photographer who finds themselves in situations were getting more in the 1 shot would be better than taking and stitching panoramas together. Trouble is i don't know what size is best from below. 1: Which will capture the most in 1 shot? 2: Is this sort of thing really worth it cost wise/quality wise? 3: Is it just the same as taking 2 pics and sticking them together? 4: Is there a better place to buy them from than eBay? 0.5 Wide Angle Lens Converter with Macro Attachment 0.38x Wide Converter 52mm 0.45X Wide Lens Thanks !
