I have a Pentax A50 f/1.2 and it's worked great at 1.2 with all the Pentax DSLRs I've owned... K10D, K20D, K-5 ( three of them ) and K-5IIs
Well that blows that theory out of the water then!

I read somewhere that Pentax use F2 sensors but just rate them as better than 2.8, no idea where though! ...............
You shouldn't be reading nonsense like that Jules

Have you seen the Digitalis test on the US forum?
Doesn't impress me

Digitalis??

Thanks John - you're right of course about film. One had to think a lot more about what we were trying to achieve pre-capture. And that was a good discipline. The danger with digital of doing it the other way round is that so many images 'lie around' on the HD untouched as it were!

That filter has certainly captured the look of some 30 plus year old slides taken out of their box and viewed. Very effective. Presumably you can take in RAW and subsequently apply the filter to make a copy?

Hi Danny
As the one who mentioned the evolution 9 - thanks for the idea as a tripod stabiliser as well!

Yes Tamrac did get into a spot of bother recently, but seem to have pulled through somehow - at least for now!

I use the Tamrac Evolution 9.

I think you'll find it can take what you're wanting to carry. Has a rain cover as well, although that will only go over a small tripod. Any tripod of any size; I bought one of those cheap £10 jobs from Millets or somewhere like that. Also has a waist buckle and has swing under the arm side access pockets for quick access to camera etc.

Have been using for last 3 years and find it comfortable. Will also take a laptop, but I don't carry that, instead use that space for my waterproof leggings and kag!

Thinking of and praying for you and the family, Eddie - hope things pick up soon for you.
