Hello and welcome. A very nice lens collection you have...there cannot be very many people on the forum with a 600mm f4! Excellent.

Tornado passing within 100 yards of my front door at 10.30 this morning on the Southend to Canterbury 'Cathedrals Express'. I thought the brunswick green of the loco contrasted nicely with the vine growing on the retaining wall. Cue a song...'red, red vine...'

K5 with Tamron 10-24 at about 20mm.

I like this very much, both the composition and the mood. I tried a black and white conversion and like it even more. A minor niggle is that two of the wires are oddly fractured and bent (maybe by the pano stitching?)

Wow! I love these...some of the most interesting views of the park I have seen so far...and you just have to love the wild flower meadows

Lastolite do a 5m sync cord for about £30. I got mine from an ebay seller.

I was in the Olympic park yesterday and there were loads of spectators with DSLRs with largish lenses (70-200 and 70-300 by the look of them). If you want to carry a second lens just get your companion to carry it - everyone goes through a separate security channel. It's hard to see how they will be able to change the rules so drastically at this late stage.

My own experience with these lenses is similar to Jules. I have the 15, 21 and 17-70. The only advantages of the 21 over the 17-70 are size and it's not SDM so locks focus more consistently. I don't believe it's any sharper than the 17-70 and for colour rendering I like the 15mm best of the three. If size and weight is not an issue for you I would spend the money on something else - a 645d perhaps

I really like this shot, a great capture. The only distracting things for me are the pylons on the horizon. Maybe they could be cloned out?

If it helps at all this is the field of view I got with a 31mm lens when I went to a test event there 5th May. I took the 31mm because it was a very dull evening and I needed something reasonably fast to get anything at all. A wider lens might have given a more interesting perspective. You can take in cameras and lenses that do not exceed 300mm in length. You will need tickets, either for an event or just for the park, to access the area at all - but I guess you won't be travelling all the way from Devon without having checked this out already

My wife seems to think so
