Also can you make sure it works with more browsers than IE please. I use Opera and get fed up with websites that don't support Opera. Thanks.

Since Kenya codeshare with KLM I am confused as to why you are putting yourself through the Heathrow torture, but if it saves a few Euros fair enough, or will you be back in the UK anyway then? Kenya are also strict on handbaggage so be aware of the weight of your kit.
I am soooooo jealous
I was hoping to go to TZ again next year but the OH can only get time off at short notice next year, isn't able to set in stone a few weeks off due to busy work schedule. TZ needs booking early for the camps we like. Ah well maybe the year after.

I took my Ds to Tanzania and it survived very well. I took two SD cards and a Vosonics Image tank. No problems.
Got room in your hand baggage for me?
On second thoughts KLM Africa can be very stroppy about handbaggage weight allowances so maybe not....
If you are flying KLM then do make sure you are under the handbaggage limit - wouldn't want to have to check the camera!

Sigma do not make HSM lenses with a Pentax fitting. They have stated that unless Pentax offer more models with HSM ability they will not be making any as the market is too small.

I like it.
Not sure about the German text mind...have to get DIL no 1 on to it!

I have Scott Kelby's book for Elements 4 - it is brilliant. I also have one by Philip Andrews but I don't like it anything like as much as the Kelby.

Pentax do a finder loupe that magnifies the whole image - the OME53. No idea what it costs or how available it is. An alternative may be an angle viewfinder that offers 2x magnification. You see them on e-bay and the like sometimes. I think the make is Seagull.

K-E is usually a bit cheaper too. Thanks for the lunch tip, I'll remember it next time I head for Den Ham.

Foolish man going to K'berg with a wallet in your pocket

Well George I don't think I'll make it to the Himalayas but lightweight is an increasing requirement for me - I take my camera pretty much everywhere I go and it can get to be a real pain after a few hours of hiking carrying a couple of lenses in the backpack. The Bigma doesn't tend to go unless I'm sure I will get to use it. We are off to Scotland in a couple of weeks, by car so I could take everything, but I'm still trying to minimise the kit to make the mountains easier.
When flying I take the gear as handbaggage and so many airlines weigh it as well as measure it. KLM Africa do for instance. I'm still hoping to get to Tanzania again in the foreseeable future, inspite of the horrific price increases there, but if I do it will just be the Bigma that goes I expect.

I will see if I can borrow a 16-45 from someone here and try it out. He may have the 40mm too, as he has a serious case of LBA. Pity the 31mm is so expensive. The only 28 FA I have found here is labeled Soft so I don't think that's for me.
