I am in the planning stages of an 8 week history/photography trip along the French and Belgium Front Lines of World War 1 beginning in early May. I will be travelling primarily by bicycle which severely limits what I can carry.

The weight of a laptop and battery would be excessive and tablets do not have the capacity to store the large quantities of photographs anticipated. Large quantities of SD cards, while certainly light enough, would be awkward, expensive and too easily lost.

I'm sure other Hogs have experienced similar situations where size and weight of storage is a factor so I am appealing for your help and suggestions in this matter.

What do you use for large quantity photo storage on extended trips? Thanks for your help.

Check out photos of the new FF Sony lenses to be announced tomorrow (Friday) at the CP+ show. They are posted on the "sonyalpharumors" website.

The lenses are huge. Disproportionately massive. I've been waiting for a Sony FF superwide zoom, and was looking forward to the new 24-240mm. Until I saw the picture of it this morning. It's so big as to remove all the advantages of the A7 in terms of size and weight.

The idea of the Sony A7 line has been great. But the lenses, not so much. Very limited selection, high prices, and now, very bulky.

I'm glad I kept my Canon gear while waiting for a good, all purpose Sony zoom. I may have made a mistake with Sony, and recommend that you think long and hard before committing.

My wife and I have hiked the Tour of Mont Blanc twice. It is a 105 mile 11 day trek with accommodation in mountain refuges and occasionally in small hotels in villages. We carried all our gear in our backpacks and since we are now both 70 we try to limit the weight. We are planning on hiking the GR5 (Geneva to Nice - actually we will only walk half which should take about 14 days). After this long preamble, I will get to the point!
We have a Canon S90 which we bought in 2010 and found it great for trekking because it fits in a small case which I can attach to my clavicle strap and can access it without difficulty. Last year we bought a D7100 and enjoy it but it is both too bulky and too heavy for our proposed trek.
My question is whether we would benefit from an upgrade to our S90? Generally we would be interested in landscapes in good light. Our experience is that long telephotos are not very useful for this application.
I know the Canon SX50 is a great camera (my son-in-law has one) but too bulky for carrying on a clavicle strap.
I would appreciate any suggestions. Would successors to the S90 offer much advantage?
I would like to keep under $500 and am comfortable with refurbished. I like to shoot in raw.
We wrote a report of our experience and a link follows:

I'm looking forward to your suggestions.
