I have too many camera bags and strangely I feel not enough when I see threads like this.
Good: Domke F-5XC
One body and lots of Ltd lenses fit, and is easy for urban travelling.
Took this one to UK-France this year for 3 weeks with K-5IIS, DA15, FA31, DA18-135WR, and a Sigma 8-16, O-GPS1, filters, batteries, cards and a few other bits. Easy and comfortable and didn't get in the way. My wife's handbag was bigger & bulkier.
not my photo Not So good: Kata DT-213
I got this one together with a waist pack Kata DW-493. I have used the waist pack quite a few times but this torso pack just doesn't work. It has plenty of padding and I thought of using it while biking or skiing or hiking ..... but it just gets in the way with all those activities. It's even difficult to get a camera out of it without smacking yourself in the face or knocking a your hat off.
It does appear a little awkward when worn also. (I was going to say it makes me look a bit of a "knob-end" but there could be other factors influencing that description
)
not my photo Good and Bad : Kata DR 466i
I needed a backpack style for transporting a couple of bodies and several lenses in hand luggage and also for use when travelling.
I don't generally like shooting out of a backpack but have to hold gear somehow.
The Kata 3in1 style looked interesting in the demos but seeing one for real it seemed it was rigid and boxy.
Good backpacks are pretty expensive and these Kata DR ones seemed pretty good. A DR 466i came up for 40bucks (>65% off) so I grabbed one. It is pretty well made and the bottom section is nicely padded with those yellow dividers and there's lots of little zipper sections for small bits and pieces.
The bad part is the DR 466i size is a bit small. The bottom section is the same "techincally" as the 467i but it's kind of squashed in and is a little awkward to get into. The top section is significantly smaller than the 467i I'd say 1/2 the volume and the laptop slot is pretty tight even for a 13.3". After buying it I saw this youtube clip with a comparison. 466i on the left and 467i on the right.
not my photo Good: Tiffen filter pouch
This is really handy. I always carry 3 or 4 filters CPL or ND's and this little pouch stuck on a belt is really handy. I put lens caps in there too. I didn't buy the Tiffen filters, just the pouch.
photo from B&H Good: Think tank Belt and "Skin" Components
These are really good if you like walking but don't like camera backpacks. - A little difficult to sit down with it loaded up though.
I've got one if the padded belts and 3 different sizes of the unpadded pouches, "Body bag" (wide one) , "50" (short one) and "75" (long one).
not my photo but the same setup except with padded belt.
Quite comfortable to carry on the hips and fits a decent amount of stuff of you don't get to crazy.
I used this setup for soccer games, motorsport, yacht racing and a rodeo (all with 2 bodies).
It's also good for hiking which I did in Tasmania last weekend and central Australia last year.
