[Brightcolours]

One suggestion; if you claim a lens is good or crappy perhaps you should describe how it is good or crappy. This might help orient the discussion around technical merit rather than name calling. There are many parameters which define a lens. Now for my 2ct on the 35f2 (non is). I have never own this lens but have never been 'wooed' by images I've seen taken with this lens. It seems to have decent resolution but  seems to be a bit dull and I personally find the bokeh distracting.

 

Btw blur does depend on more than just aperture (or equivalent aperture). Lens design can change not only the bokeh but also the amount of blur given a fixed focal length/aperture/format. There is an interesting zeiss paper that discuss how the design can impact the transition around CoC.

Good suggestion, about describing it not being crappy.

So, yes, it is actually quite sharp, even usable wide open. It's contrast is ok, but still seems to lack a little. It's bokeh can be remarkably smooth (but not always). It is small and very light, not expensive and focusses quite fast and accurately. It also behaves VERY nicely at close focus distances, so with the appropriate extension tubing it can be used for close up/macro stuff. Its short build helps with that.

 

On FF it is said that the extreme corners get soft in an abrupt manner, but the weather has been so that I have not yet been able to test that with my 6D.
