Last: EF 40mm 2.8
Next: Nodal Ninja or better ball head.
I bought the 40mm pancake because I wanted to play around with a fixed focal length lens on my 5D3. I'm on the fence regarding my next purchase, mostly because I just bought the 40mm today.
Looks like I'm changing up my next purchase.
Next: Canon S110 or Sony RX100 Mk.III
