LoweproPro Trekker Camera Backpack from Lowepro – Large Capacity Backpacking Bag for All Your Gear

I have used the 600AW mk III for over a year now. Addressing some of the comments made by other reviewers.1. This is a special purpose bag designed solely to hold a 500/600mm lens with a body ATTACHED. This is made quite clear in lowepro's description. It is not a small version of the 650AW, the latter being a general purpose customisble bag (which, to my knowledge, cannot carry a 600mm with a body attached). Please do your research and do not complain about the lack of internal dividers.2. The mk III torso fitting system is called ActivLift. Pack Jack was in the previous mk II. Since the shoulder straps are part of the ActiveLift plate, it's not possible to wear the bag without this present. If it's not present, it's a packing fault at the factory, not a defect in the bag.3. The lens collar IS included - it's a structural component of the bag and necessary. If it's not present, it's a packing fault not a defect in the bag.4. My bag with lens, body, teleconvertors, large tripod, gimbal head, weighs 12.5kg of which 12kg is kit. The bag's weight is negligible when carrying large kit and not a defect of the bag.5. The lens capture bracket/collar fits snugly around the neck of a lens, is height-adjustable to handle 500/600/800mm, and is placed so that the lens is centred in the bag. It is asymmetrical and not necessary for the front half to be shaped/contoured.6. There are vertical sliplocks running top-to-bottom of both sides of the bag, stitched into 4 (elastic pocket side) and 6 (other side) spaces. There is one horizontal sliplock running front-to-back on each side of the bag, at the height of the top of the zip pocket, stitched into 3 spaces.7. The lens foot fit is tight if you use the larger foot type, but will fit comfortably. I find it useful to brace this against the opening side as an extra support for the lens.8. The zip pocket is sufficient to carry: A tripod tool bag and three 3-inch diameter hemispherical rubber feet. A bicycle multitool with various hex keys. The lens/body/teleconvertor end caps. The soft teleconvertor storage bag (teleconvertor is on the lens). Spare batteries. A travel pack of tissues. I also carry a second teleconvertor in the main compartment next to the lens, but this must be removed when extracting the lens.My thoughts on the bag...A. I would like to see more padding underneath the bag. There appears to be around 1 inch of foam. Since the large lenses tend not to have hard plastic lens caps, and their front elements are vulnerable, more protection here would seem sensible. However, I accept it may compromise the stability of the bag, and the user can always fit more foam, or a hard plate, inside if required.B. It is only possible to attach the tripod foot carrier level with the base of the bag on the non-elastic-pocket side. If you have a very large tripod, or a large gimbal attached, the tripod head will protrude above the top of the bag if attached on the other side. I don't personally find the elastic pocket useful, but others might. I also don't have a problem with the tripod being on one side, but others might. Sometimes I want a second tripod with a scope, but I just carry too much kit ;)Overall I find the bag excellently designed for its very specific purpose. I have not tried Tamrac or Manfrotto bags designed for the same purpose. They may well be better, but the Lowepro does its job.

I have used Lowepro products for many years. I only bought a Think Tank bag a few years ago because my High Street store had stopped selling Lowepro bags. Last year I bought a Canon EF 500mm f4L USM lens to attach to my EOS-1D X MkIII and I needed a bag to carry it in. Due to the size of the combination I was limited to the choice of two bags - this Lowepro Trekker being one of them. Neither of them were cheap so I carefully considered which one would do the job the best. I chose the Lowepro one.It is a very comfortable bag to carry on my back with a useful top strap to lift. The bag has ample padding to protect my valuable camera and lens. It can be a little fiddly to locate the lens in the recess at the bottom of the bag. Equally it is not particularly quick to lift the camera from the bag and return it. This is due to the padding which is attached to the opening flap with Velcro needing to align with the Velcro attached to the padding in the bag which supports the lens collar. However this is no more than a minor inconvenience which is offset by the fact that the camera and lens is well secured within the bag. There is space at the top within the bag for a cloth or other small pieces of equipment. The pocket in the front is big enough to carry a lens jacket but not much else. It is a good practical bag for carrying the camera and lens that I bought it for. Above all else it is very comfortable to carry and provides good protection.

If you have a Canon mirrorless (R5/R6) + the EF 600mm Mk2 lens + EF/RF adapter + x1.4 extender bag is tall enough, my mistake for the thought that it did not, it all fits great. I also sling one of the lens cases on the side for extra storage.

The design of the bag has been well thought out. it holds your telephoto lens up to 800mm very securely plus there is room for other photographic equipment. Anybody thinking of buying this bag or any other similar bag should also consider that with your lens the total weight involved can be substantial, even though this bag has carefully been made to work has back carring load.Would fully recommend if you want to protect your valuable Lens.

Having owned an original lenstrekker which was good until the shoulder harness broke and having subsequently tried a manfrotto tlb 600 which was poorly designed I returned to my usual lowepro bags in purchasing this oneThe bag is larger than the original lenstrekker and holds my Canon 1D my IV and 500mm F4 L lens with teleconverter with the hood reversed. The bag is well made and the straps make for a comfortable fit. I have only given 3 stars for the following reasons :1) the bag was supplied without the plastic pack jack which allows the harness to be adjusted to suit your torso2) the front pouch for carrying accessories is a little too small. I have managed to squeeze a pair of binoculars in but that's all3) whilst there are sliplock loops to attach lowepro pouches the vertical loops are only on the base of the bag which limits to some extent the number and size of pouch you can add. Leaving the loops at the top of the bag as per the previous versions of the bag would have given the wearer more options4) the elasticated side pouch and waistbelt pouch seem very flimsy and I suspect will tear fairly quicklyThat said the bag is great for carrying large lenses and as with all lowepro bags a comfortable fit

Perfect bag for my Canon 1D and 500mm lens.Considering the weight of the kit, it's very well balanced even with a carbon fibre tripod strapped on the side.Usual high quality from Lowepro. (I have 3 of their bags for different use and my 12yr old dryzone bag is still in great condition).

Fantastic piece of kitV comfortable. Protects camera and lens v well
