I'm like JR - I've tried a number and most are piled up in the spare room now. The one I am currently addicted to is the Slingshot 200AW (http://products.lowepro.com/product/SlingShot-200%20AW,2035.htm).

The biggest problem I've had with waist, bum, reporter type bags is easy access when you want to change lenses. The sling type bags work brilliantly in this regard as you don't even have to remove the bag, or fold over a flap, to change a lense and access is simple and convenient.

I may upgrade to the 350 AW as I could get two more lenses in and an iPad / notebook. But the temptation is always to put in more than you need !

When going on a shoot, in the 200AW I have (or similar) :
K5, K7, DA*300, 50-150, 43 Ltd, 17-50, Metz 50 (this lays on top of the K5 with attached 50-150 with a small cloth in between). The other pockets can take all the substantial amount of bits and pieces I need and there is an integral raincover stowed in the base.

When I arrive on site I use two Black Rapid singles (I prefer these to the double harness as I can always take one off if I wish) and then the bag is accessible for lense changes (as otherwise the Metz would get in the way).

Tamrac make some nice bags like these too.

It certainly is interesting reading -landscape togs will be devastated !

Thanks for posting the link.

Plenty compared to your comment that it is a final product.

In fact even in a basic P&S often it's possible to perform in camera PP, we know in DSLR's a lot more is possible so therefore manufacturers of cameras and software are not saying that a jpg is a finished product. It is a convenient product; easily transferable, space saving, easily read - but that doesn't define it as a 'finished product' even though we know it's far less manipulable than RAW.

Sorry Stefan but that simply isn't true at all. Less information there may be but there's plenty to play around with - especially from the K5 and I would assume the Kr too.

A Pro I know only shoots in jpg - and he is an AP shooter - but still does plenty of PP when needed.

IMO the main advantage is critical - increased working distance during macro shooting which usually also means more light and less chance of frightening off your subject !

This shot just posted was taken with a Tamron 90 & Viv x2 macro TC : link

However if you want to use it for distant subjects then you shouldn't buy a macro converter, rather the Tamron x1.4 is excellent or for more money the Pentax AFA x1.7 is also superb. You retain AF with the AFA but only after you MF to within the approximate distance of the subject - so it can also be used to convert MF lenses to 'semi-AF' !

Most people accept that a x2 TC will lead to more degradation than a x1.4 or the x1.7 though sometimes it's not that visible unless pixel-peeping.

DA*300 is a fabulous lense. I love #5 - great capture.

Lived there for 3 years so from my recollection (18-20 years ago) : firstly it does depend on which city you are going to visit - Vienna has far more tall buildings than any other city in Austria. Also once up in the mountains both wide and long (esp. for framing and detail, and maybe wildlife) would be required. Take some plastic bags and heavy rubber bands will virtually negate the need for WR soooo : 10-24 / 55-300 and stick the 35 on for atmospheric evening / night shots as you have no other fastish lenses. Forget the flash.

Let's be honest, they don't actually weigh much anyway do they ? There are no heavy lenses there. If it were me I'd take all four and leave those I don't plan on using in the next few hours hidden in the hotel room !

Nah .. the River Dee or Severn bores will do it

Thanks Steve !

Thought you all might want to see an 85% crop of that eye :

Ha ha - thanks Spider.

Sean - my mistake - my K7 has 30k, the K5 has around 15k.
