Also enjoyed reading your blog entries...amazing adventure.

A quick question on the bramper. How did you cope with aperture flicker once you twisted the lens back on? Deflickered in post? I've noticed flicker on the 24/1.4 II when closed down beyond f/2.8.
hi Colin

thanks. the sequences have been deflickered in LR Timelapse but they only required a very mild dose of that. light level is changing fast in these sequences when the lens is at f2.8 so not very noticeable at that point. i settled on moving from f22 to f2.8 after deciding that even f4/f3.5 had too much flicker.

the biggest problem is the change in vignetting from f22 to f2.8 and then each step down to f1.4. that's been dealt with as best i could in lightroom but it's still there if you look close.

cheers
Phil
