Finally got out and had a first play with this freaky little lens. Wow, it's a wake up call when it comes to shooting in manual - quite fun actually. Each of the pics are not "re-takable" as the manner in which the lens was bent and compressed is not stored. I started to get better and better at visually aproximating the exposures too - all @ f/8 btw Here is what NC shows in the RAW EXIF data - zippo ! Finally, one taken inside under super high ISO I definately need more practise though.
