You're a git. It's as simple as that.
...Only joking fella, they're really great shots - and there's easily a couple that look like it'd be worth them going up against Andy Rouse and the rest in some competitions.
But yes, my first comment was a knee-jerk reaction. I've just about sorted out my shopping list for my kit-bag upgrade, and I had just talked myself out of getting that glass with it - and now I'm thinking again. It's both frustrating and a blessing that the 28-300 at an extra few hundred quid is only a 3.5-5.6 - I'd probably never wind it out much beyond 200mm anyway, so not worried about the IQ at max length (I've got a 170-500 that I use if I need silly zoom) but it'd be very useful to get inside 70mm without swapping lenses. I've got a 70-300 4-5.6 at the moment and there are times when I find myself swapping between that and a basic 18-55 quite frequently.
The more pocket-friendly plan I had settled-on (trying to convince myself it was beneficial in terms of lens-swapping (beside the fact I count being able to swap lenses whenever you like to get the best glass for the shot one of the primary benefits of SLR)) was to get the 18-200 IS, but that f/2.8 glass of yours is in a different league. I've been reading nothing but good things about it for ages and that's tempting enough, but now it's on ASN too! Do you reckon my Bank Manager would agree it's an omen?
...And if he'd agree to that, maybe a second new body to make life easier too?
Anyway, sorry for the random waffle, and again - stunning work bud!
Regards,
Rob.
