The harness looks great, but the reality is, I'll never wear one-- it's hard enough for me to get out the door as it is! I finally got sick of dealing with my mirrorless cameras on a holster... The Fuji XA5 is too fiddly with the touchscreen to shoot fast. The Canon R100 with a 28mm lens is workable, but of course I'm limited to just that lens, and getting it out of the holster-- and I've tried three or four-- it's just not that smooth. I'm sure I'll still use it for some rides, but...
I couldn't find a reasonably priced contemporary compact point-and-shoot with a retractable zoom with a decent sized sensor-- all of this gear is now over $500, or lacks a flash, or has a flash but only goes to f 2.8, etc. In desperation, I got a 'good' (quality rating) used Sony RX100 first generation on eBay from Japan, and added a wooden grip that adheres to the body so you can get it out of the case faster, and got the stock case on eBay with two zippers... man, with tax and shipping, it still bummed me out to pay over $300 for a used 14-year-old point and shoot! The body has missing paint (touch up paint is useless, just scrapes right off) and I bought three different types of 3M tape to get the grip attached.
Once I started shooting with it, however, I quickly fell in love with it. It's just SO easy to work with, particularly on the bike. Good auto modes for when you're really in a hurry, a lot of control for when you are not, decent zoom, wide enough, great low light performance and surprisingly good IQ! It really nearly rivals the X-A5 and the R100. If I ever find a moment, I'll attach a couple of shots from it, and a shot of the camera itself, I just find resizing and uploading photos here is a real project (partly because I don't use any online tools for photo storage or processing.) So far, so good. It's great for on-the-fly pet shots or backyard wildlife as well.
And, best of all, it's light enough for a weight weenie like me!
