But I am also ever on the lookout for a much smaller bag that will accommodate a single camera equally well without the extra bulk. The ideal bag for this would be just large enough to swallow a DSLR with a zoom lens attached, but no larger - so that it's tucked in behind the saddle without the sides sticking out. It would be fantastic if the bag had a padded insert, but not a dealbreaker if it does not; I can make my own. Finally, I would like for the bag to have the look and feel of a classic saddlebag: earth-tone canvas, that sort of thing.
A bag such at the Velo Orange Croissant, or the Berthoud it is based on, would be perfect for the job if just a tad larger. Unfortunately they do not quite fit my camera comfortably. It looks like the similarly shaped Acorn and Zimbale bags are slightly bigger, but I am not certain they are sufficient either.
After seeing the dimensions of the Carradice Zipped Roll, I thought that it would be large enough. But while the bag is large enough in itself, the opening is quite narrow and I cannot get my camera through. The Zipped Roll has now become the Co-Habitant's handlebar bag.
This United Pedal saddlebag I spotted at the New Amsterdam bike show had the same issue - the bag itself being the perfect size, but the opening too small to fit a full-sized camera through.
It occurs to me that a traditional Roadster saddlebag design could work as well - only made of lighter fabric, so as to make sense on a roadbike.
In this era of small-scale bicycle bag manufacturers, I think it would be a great idea for someone to design the perfect single-camera saddlebag. So many cyclists are also photographers and would love to carry an SLR on their roadbikes without having to mount an expedition-sized saddlebag every time.
If you carry a full sized camera in your saddlebag, what is your setup?
