.....for my NEX 5N. I just destroyed my second Sony 16mm f2.8 today. I fly them on my radio control helicopter to take aerial photos. Unfortunately the 16mm f2.8 pancake is now on back order. I also want to find something a bit better in image quality.
I have the SamYang 14 mm f2.8 but it is so heavy it triple the weight of the 5N combination. I have all sorts of adapters but all the ultra wide angle rectilinear lens are very heavy.
So does any know of a very light ultra wide angle lens for the APS-C size sensor? Plastic housing is better and I can suffer with f4 if necessary.
I tried the Panasonic 14 mm f2.8 pancake with a adapter and it has a lot of vignetting.
I will even settle for a zoom if it is light but the lightest seems to be the Canon 10-22mm and it is nowhere near as light as the Sony 16mm pancake.
I have looked at the Voigtlander 12.5mm for a Leica M mount but it is f5.6 and heavy. The Canon 14mm L is nice but again it is heavy and very expensive to crash also.
I really appreciate any suggestion.
