I am fairly new to this hobby, just got a T4i with the 40mm pancake after I cancelled my amazon order because I couldn't wait any longer for the 18-135 STM to ship. I know some of you have ordered the lens separately from Canon and some are now showing up at best buy. I am curious to what your first impressions are with the lens, as the pancake has gotten so many good reviews (from what I have found). Just curious as to what you think about it so far...
