There are sooo many incremental improvements on the GRD III that its impossible for me to pass up the upgrade. The f1.9 lens is the prime improvement.
Yes, I would prefer to have the 40mm option but its not a deal breaker - I will be getting a GRD III. I still intend to get a 40mm for my GRD II but Ricoh should reconsider the GRD III - they can always bring out one later. 40mm is great for 3/4 portraits inside and I am currently experimenting with my DP2 for this.
Is there a way to attach the GRD II 40mm lens to the GRD III and then evaluate the image circle and vignetting? Could you use the GRD III and just mount the II 40mm on the GRD III tube?
It could be a whole new type of special effect.
