I was looking for a bag for Canon 700D with the Canon 18-135mm STM lens Always plan. I ordered my first variant M and backpack.
Variant M was way too small - the camera with the rather large lens did not fit purely the best of intentions. Recommended for Bridgecams or DSLRs with small lenses. Bounced!
The backpack was good from the size. However bothered me that he, as he has only one strap, somewhat uncertain rumwackelt on your back when you carry it. The strap is made außerdemdem for little people, for me (190cm) too short. Feels like this on, like you're a size Ikea bag hanging over his shoulder. I can think of for example. not imagine for a city break, so: be returned.
Then comb size L: Super! The camera fits in exactly. High-quality workmanship. Man wearing the bag as Seitemtasche around his neck. The pocket is open at the top and it must not be "drawn out". Very comfortable. The camera will disappear with the lens facing down into the bag. I have the "Velcro partitions" set so that the camera seems to float freely in the bag, so do not rest on the Objektv. The bag is suitable for the 700D with the 18-135 STM on the size on the cm (!). Under the lens 0.5-1 cm square, the cover of the bag is almost on top of the camera. Well packed is also room for a Standartobejtiv or two small lenses. Moreover, in small compartments is still room for a spare battery, a different SD memory card or on the strap (the can well next to the camera "stuff").
So if a bag for a Canon 500/550/600/650 / 700D with immerdrauf lens investigated, which should be as small as possible and is very comfortable: slamming, unrestricted recommendation! Anyone looking for a bag for several lenses and accessories, needs something larger.
