Cycling and cameras

If the vibration isn't a concern, how about a container that fits in the water bottle cage?

I do more touring than mountain biking so I usually use a rack-mounted pannier. I also have a small LowePro Top Load Zoom that works for a camera and lens of that size.

I'm a commuter, not a mountain biker, so I have a pannier on the back, a basket on the front, and a trailer that I sometimes use for bigger cargo. Lots of options. I actually built a GoPro mount into the frame that holds my basket, because I found that unsupported baskets always eventually break on me.

Today I'm thinking of a similar project (camera looking backward from the luggage rack) where my phone is on the handlebar mimicking a digital rear view mirror using video (need one anyway due to an age-induced stiff neck) and a button that enables me to save images that I find interesting from the video stream. Work in progress.

I have a Brompton and when I take my camera with me I put it in the bag that mounts in front of the handlebars. I wrap it in some soft fluffy material to protect it from any possible impact damage.

I have a front rack, a back rack, a back basket, quad pocket panniers and a backpack. Take your pick.

I routinely "ruck" with a 50 pound pack — no hip belt. However, while riding a bike I can only tolerate a (much lighter) backpack (beyond a water bladder) for rides of 10 miles or less. I use a small (waterproof, as in submersible) Revelate Design handlebar bag for my camera. (It works on my mountain bikes as well as my gravel grinder and bikepacking mid-fat.) Revelate no longer makes the bag I have, but last I checked, Chrome Industries has one that is similar. Barring that, I have in the past adapted a “bum bag” using a cow-hitch (aka larkshead or luggage-tag loop) in the waist belt to fasten the bag to the handlebars.

If you absolutely can't fit a bar bag I'd look at waist packs — Wearing a backpack in a riding position aggravates my neck and shoulder muscles.

If you must use a backpack, I've found the Osprey Syncro 12 to be the most comfortable amongst the many and legion I've tried. (Several of them still sitting downstairs in my "bag of bags"…right next to the "Big Domke bag of camera bags".) However, backpacks, like shoes, are highly personal in their fit and comfort. Other people's fit advice is of little value. You have to try them for yourself.

Yeah. I do lots of mountain biking with a camera, and my favourite solution is a kids school backpack. Because I'm heading out into the bush, I'll take a tube, small, compact hand pump, some lightweight plastic tyre levers, and a set of Allen keys, I need something to carry them, so it's a no brainer to have a small backpack that I can also throw the camera in. Phone goes in it too, if I take it, more comfortable that it being in a pocket digging into you at the worst possible moments.
The good thing about a backpack, is that my fat carcass makes a fabulous vibration and impact insulator. Unfortunately been tested on a couple of occasions, vigorously enough to put me in the back of an ambulance with a broken hip, and a trip to the operating theatre. Through no fault of my own, after being run over by a 4WD. Camera and lenses were unscathed.
I've got a few of those neoprene lens pouches with a drawstring that I pop any extra lenses in, just to stop them rubbing against each other in transit, and I just bought one of those square neoprene camera wraps/covers, that have Velcro on a couple of the corners, that will work nicely on any smallish camera with lens.
I think it's a great setup that I've refined over the years, riding motorcycles as well as mountain bikes.
Works for me

One more thought…I can slip the X100V into a Revelate Feedbag. (Think of a climber’s chalk bag mounted on either side of the steerer stem behind the handlebars.) I don’t think the XT5 would quite fit in mine, but I have seen them larger. Feedbag is attached to the handlebars and stem. Visible just forward of the “Tank” bag:

This is the waterproof handlebar bag I mentioned earlier:

This is the sort of stuff my camera/s get dragged around on 😁 No cupboard Queens here

In the feedbag department I have reports from another Fuji user that this product (US Amazon link) works with a “small DSLR”: www.amazon.com/dp/B08JTMZH4D

I need a camera bag for my bike. Recommendations?

Maybe something like this:

Senxry Bike Handlebar Bag, Insulated Thermal Bike Cooler Water Resistant Bicycle Bag with Touch Screen Phone Holder Outdoor Bike Accessories for Kids Girls Boys Men Women Scooter Cruiser 3.5L a.co/d/inGy3NB

Have you considered a Cotton carrier harness? That would certainly provide rapid access but would not work if you do extreme biking where falls are likely.

Not much room left on the bike. Maybe a small sling bag or a holster bag.

For me "seriously" riding my road bike and doing any "serious" photography are mutually exclusive. I should probably take myself less seriously. Anyway, I would suggest a compact camera that fits in the pocket of your jersey; I've tried it, but found it just takes up space and my iPhone is adequate for any quick snaps I might take (but practically never do).
