Won't it work on your P30T in Program mode?

Welcome Les!

It's simple enough to find out because Philip can try it out on some local buildings.

Philip, it depends on how tall the buildings you have in mind. It's better to have the correct lens for the job if you can, so maybe you need the 55-300mm after all?

As always, it really depends on your photographic style. If I had your lens kit, then I suspect the 18-135mm would be in use 95% of the time. I would also take a faster lens for low light opportunities, so the 35mm would be included.

The flash I would not bother with. Flash kills atmosphere and with the wonderful high ISO pereformance of the K-5 is of limited interest whilst travelling. In extremis there is always the built in flash.

Just the two lenses you would probably get by with, but adding the ultra-wide would be useful for some interiors and other architectural shots in cramped conditions.

So in summary, of the kit you list, I would leave behind the 55-300mm and the flashgun.

Don't underestimate the kit lens - it's very impressive for the price. Stopped down it produces extremely good results.

Please check out the link to my EPZ review of the lens. The link is on the right hand side of this page.

For me the secret of a good bag is one that's easy to carry, easy to get access to (this puts most backpacks out), roomy inside but with the minmum of wasted space. Kit should be held securely and firmly, but not so much so that it's hard to remove.

It's a very personal thing, which is why we have a cupboard full of unused bags....I must eBay some of them.

There is a London WWT (Wildfowl & Wetlands Trust) site that will offer lots of fast moving wildlife to challenge you.

K-5 + 18-55mm or 16-45mm + lens hood, spare battery, torch, paracetamol, case of empty SD cards, case for full SD cards, 55-300mm + lens hood, 12-24mm + lens hood, 35mm f2.4, 100mm Macro + lens hood, maps, model release forms, pen, any other documentation, and there would still be a bit of room left for odds and ends.

I don't usually carry quite that much, but that is what is possible if needed.
