For those who have the 16mm pancake, it's a "no-brainer" for everyone else at least one serious worth considering: namely instead of Walimex to buy the VCL ECF1 fisheye converter intent. The costs only 116 euros and offers in combination with the 16er following advantages: better image quality, more compact and easier to autofocus (certainly in this case dispensable). The only point where the Walimex slightly has the edge: A larger by perhaps 1-2 degrees angle of view, nothing really drastically.
In addition, the 16er also allows the use of wide-angle converter of even costs only 98 euros!
So: Walimex can only Fisheye, costs 280, is large and heavy.
Sony 16er Pancake with converter will cost 370, is better, lighter, smaller and on top of that provides a super compact 24er (KB) lens. Make Super Wide In addition, the option of it for 100 euros a 18mm (KB) (with more than acceptable image quality, and very little distortion)
