I brought a Pentax 67 + 105/2.4 and 30 rolls of slide/10 rolls of b&w to France this summer and loved every minute of it. No color correction filters, no light meter beyond my phone, no problem. 35mm slides just aren't the same. Yes it added to the cost of the trip but I'm not complaining.
Looking at the transparencies with a good eyepiece, I'm instantly back on the Champs.
