Just got a Sigma fp for a trip to Japan and I'm lost.
Sorry if this is a dumb question but I have no idea where to start with all these cages and grips and stuff...
To add to the point above: the fp writes huge 12-bit DNG files, so write speed is more critical than a cage for street photography. The buffer lags on slow media.
Honestly, i think you should be really careful with how tiny it is. IIRC, people say it can slip pretty easily when you're walking around Tokyo. You might want to consider:
Stumbled on this while looking at sensor data on CineD. Taking a similar setup to Osaka last year taught me about data reliability. My cable wiggled loose once and it corrupted several files. You wont want that happening on a big trip.
