im looking for a new bag for sigma my 150-600 with body attached

i am looking for a new bag to hold primarily my sigma 150-600 with nikon d600 attached and a small 24-85 lens. i have minimal accessories but am looking to add some gear in the future (like a macro lens). i would also like a bag with plenty of personal space for stuff like lunch or a jumper. i am struggling to find a bag which meets this criteria under £200 so i could use all the help i could get. thanks, Dennis

What style of bag are you looking at? You might have a tough time finding a shoulder bag that would fit your requirements. I have a Think Tank holster that takes a camera mounted to a long lens, and would take your Nikon and Sigma, but that's about all.

Short of an airport roller, you're probably looking at a backpack. Google 'long lens backpack'. A bunch of manufacturers make them, including all the major players. If you can get it narrowed down to 2 or 3, there are probably people here who have used those specific models.

Edit: Thinking about it, Think Tank makes some giant shoulder bags in their Retrospective series. Anything bigger than about their size 40 will probably hold enough, but be warned, they're huge, and when full, very heavy.

I use a Thinktank holster as well, crossbody carry for hiking. I also store the lens with the camera in it.
