I'd prefer the FOV of the 20mm (& the speed), but the AF speed sounds very off putting.Its not that its bad, its just that there is a superior option in the 20mm 1.7 which beats it in almost every conceivable way. The only reasons youd buy one is if you absolutely had to have the 3mm difference, which is practically nobody, or if you found one at a great price.
Otherwise the 20mm panny pancake is just flat out a superior choice for most people
Then you should not be buying the 17mm f2.8 either. It is no faster than the 20mm f1.7 and uses the same type focus system as the original 14-42. No internal focus, so it is as slow at autofocusing as it gets for an Olympus micro lens.I'd prefer the FOV of the 20mm (& the speed), but the AF speed sounds very off putting.Its not that its bad, its just that there is a superior option in the 20mm 1.7 which beats it in almost every conceivable way.
