The larger hold with downturns for both center and band fingertips should easily provide arms of every size, while there’s adequate thumbs area on the back in between the various manages. It’s also welcome to see the manages which were placed on a mountain between the back and top-plate on the A55 are now more ideally experiencing the consumer at a higher and much more relaxed position.

The only gripe here issues the power receiver around the shutter launch key, which would benefit from being more unique, either in size or structure.
