Thanks all - first time posting for feedback so thanks for the encouragement.
For B&W, i was going for the documentary style but I also took a lot of environmental portraits in colour (see flickr). Cuba is great for BW but it deserves colour too. Luckily I took a friend's advise and packed the m8 instead of just the m7 and BW film.
The DP1 was my 'wide' (28mm efov) good light & high iso BW camera.
I had the 35/2 cron IV, 50/2 rigid + CV 15/4.5 on the m8. The rigid (efov 67mm) was used for the environmental portraits. The CV was used for the wide work. The cron IV saw the least use.
The m7 had the CV 35/1.4 MC as a lens cap. I wanted some 'vintage' look on film to give it a different look. I will be posting film soon.
It was an amazing trip...13 days, driving around with my very understanding other half and 15 month old. I'm glad I took the challenge going...not sure I am able once the little one is older/when the next one comes around.
