Thanks Stefan. I'd looked at the Lowepro stuff in my Local camera shop but they did't have a full range - the Primus AW looks just what I'm after, I'll try and find one to look at.

Hello all.
I'm trying to find a rucksack for my particular needs but the photography specific ones that I've seen don't quite fit the bill.

I'm after a sack with a smallish padded section for my K100D with 16-45, space for a 55-300 and 50mm with 2x converter. Would also be useful to have space for a flash in future.

This is easy enough to find but I also want a decent amount of space for items that I may need on a walk, such as waterproof, warm top, food, flask, etc.

All the rucksacks I've seen don't seem to be geared up for the requirements of a walker - they seem to assume that the photographer will not actually be walking very far

Any ideas?
Cheers

I've just bought a 55-300 from SRS for £189. It replaces a Tamron 70-300. Not had much chance to use it yet but what little I've seen with it I'm very please. It's small and seems better built than the Tamron

Cheers hefty1.

I have the above lens but have not been able to find anything about it on the web. My question is: -
It has a standard manual focus, then moving towards the camera it has variable aperture f8-f22 ring. Next is a ring which has O C. This interacts with the apeture ring when moving from O to C in that it pushes the aperture from f22 towrds f8.
Any idea what this is or does?
Not sure I'll get any decent photos with it - Not convinced it is any good.....anyone used one?
Cheers

Thanks All. Seems I may be alright - if not I'll cut down a standard or get a slim holder.

Thanks for you quick replies,

Pete, where did you getb the Tian Ya P holder? I may need to get one if I have issues later

beakynet - I too have been OK with the kit lens but this falls within the 28mm recommendation!

I have a set of Cokin P filters. The Cokin site says that they are suitable for focal lengths from 28mm. I am about to take delivery of a Pentax 16-45 which is a 35mm equivalent of 24mm at the wide end. Does anyone have any experience of P filter system and this (or similar focal length lenses)? Am I going to have problems with shading around the edges (vignetting?)? If so can I just cut the outer slot or two from a P mount or am I going to have to invest in larger filters and mount system?

Thanks that's exactly what I wanted

I have a nice Pentax-A 50mm f1.7. As well as using this as is I also combine it with a really useful 2x Macro converter. This gives me both a 100mm Macro lens and 100mm telephoto. My question is what would be the max aperture with the converter assuming a loss of 2x f stops. Is there a table somewhere of "standard" apertures etc
