Hi Chris
These shots seem particularly sharp - well done!
There is no shortage of quality in your Sigma 12-24, as demonstrated in this and your other posts.
Speaking of W/A photography generally (not lenses specifically) do you find that you almost need a different mind-set using W/A lenses?
Maybe it's just me, but I have always felt that I have to get into W/A
mode. Today, for example, I went out with just my D70 & the 12-24. No camera bag. In fact, I had to buy the CPF at a camera store just before using it.
I find that if I have W/A lens just as part of my kit, I don't seem to find many W/A opportunities. Obviously, the photo ops don't simply disappear - it is all in attitude.
I love unusual perspective shots - that's why I find W/A so appealing - but I can't say that it comes naturally to me.
What are the thoughts of other photographers here?
