Excellent product excellent service

The bag is very well made and feels durable. Billingham bags have a reputation for longevity and being waterproof. I haven't tested this myself but I trust the hundreds of reviewers who have and confirmed it for their bags.
As for size, the Hadley One is very spacious. The main compartment comfortably fits a full frame DSLR with lens attached, three additional small-medium size lenses, a filter pouch, and there's still room to spare. I could travel with this bag if I dropped a lens or two and instead filled it with clothes and toiletries.
I was initially concerned that the leather joints at the ends of the strap might struggle with the weight but they can handle this and probably a lot more. With my current load they don't even bend.
I bought this together with the SP50 shoulder patch that is sold separately, and it makes carrying the bag a lot easier. I'd recommend the shoulder patch to everyone who considers buying this bag.

Great price for these quality panoramic papers. I haven’t used any yet, but should work well with my Canon photo printer. They were well packed by Harrison Cameras and very quick delivery.

Perfect secondhand quality

Great service. Straight forward and speedy delivery. Will use again.

I thought the packaging was excessive. A bubblewrap envelope wouldhave been fine.

Has a great feel very light weight, meaning ideal to carry.
Image stablization enhances this model further,once you get used to handling the lens photos will improve.

I order this paper, as I had used it before and was pleased with the results. I have not used this company before, but I was very impressed with their packaging, prompt deliver and general service. I will definitely use this company again.

Fits well and screws on nicely, looks well made. I have no complaint about the effectiveness, although I've no experience regarding comparative tests (like most amateur photographers, I use it to protect the much more expensive lens).

I love this lens.
Prior to purchase I'd seen many positive youtube articles about its performance, the reviewers seemed to be happy accepting the slight limitations associated with a wide range zoom lens, stating they were well within expectations. One final reviewer was not so happy, and even returned his purchase for a refund. This almost deterred me, but I took the plunge anyway and I'm glad. Yes, at full zoom it'll be a bit limited in low light, but otherwise it performed better than I expected. Very slight chromatic aberration can be seen on dark edges against white backgrounds when pixel-peeping towards the edges, but not a problem, and this is a £600 relatively compact lens, not a £3000+ monster!
One point to be born in mind, I use the lens with a Sony a6400 and first time I used a Sigma lens (i.e. a non-Sony lens) the in-camera automatic aberration and distortion correction was defaulted to "Off", so make sure your own camera has these or it comparable setting changed to "On". Perhaps the negative review had this setting disabled?
Great lens - I recommend this for those days you need that zoom flexibility with extra reach, and don't want to lens-swap, and the 18-50mm F2.8 Sigma for indoors, or outdoor when the the better aperture is more useful than tons of zoom.
Oh, and the build quality feels and looks superb.

Just what I was looking for. Arrived very quickly.
