good bag for easy access to switching lenses?

whats a good bag to use, so i can switch lenses easily without having to place the bag down or focus so i dont drop anything out of the bag while trying to switch lens.
i only shoot for fun, but do end up switching lenses when out and about, especially if my kids are running amok at the park.
but basically i find it a bit of a hassle to have to switch lens using a backpack , especially when i am trying to switch the lens asap.
ive seen that maybe the crumpler might be my best bet, but it does look pretty huge, especially the 7mdh. I currently only got 2 lens, but i will soon be buying the 135L or 85 1.8 & 70-200F4
so i will either have 3 or 4 lens altogether.
i also looked over the slingshot, am i right by assuming its not too practical to be switching lenses with it while its strapped on?

I HIGHLY RECOMMEND this bag. It is the Domke F803 and it is AWESOME!

It does not come with an insert, so you need to buy one. Mine can hold 40D, 10D, 400L, 24-85, 28mm and 430EX. I got it because it could hold the 400L, as most bags are not tall enough. However, it feels very comfortable, is pretty small, and is very flexible. It can actually hold a smaller laptop as well (smaller than 15.4") in addition to all the camera gear. One of the nicest things too is the rubberized strap. Other bags slide around when you crouch down, but this one stays put. When i want to change lenses, I slide it to the front, grab my new lens, rest the camera on the bag against my body, and then swap. Very easy. I have tried backpacks, and they suck compared to this. Other bags can't hold as much, or they are way to big. Plus, there is no way to tell this is even a camera bag. I left it in my car a couple times on a road trip and was not worried at all that it would draw a bunch of attention.

You might consider a Think Tank belt system or a Think Tank Change Up bag with a Lens Changer.

canonlaw- thanks, but thats going to cost me about $150, i think that might be a little too pricey for now. also thats crazy man leaving your bag like that in your car.. some people will just hit and grab any bag they see in a car, one of my friends car recently got broken in to, he had like a tote bag with some books inside.. and thats all they took.

ill try take a look into thinktank

I will second Jhom's suggestion or a similar Lowepro beltback.

The bag and insert are $100 on Amazon, which still might be too high for you. I know what you mean about people taking whatever bag they can see....it still makes me nervous, just a little less so. Plus, it is small enough to slide under the seat so there is nothing easily visible at first glance....... :-p

$100 for both? on bhphoto it shows bag for $100 and insert for $40
lol, yes the do slide under seat!

I use a Lowepro Nova 2 (shoulder bag style), and it works okay for switching lens on the fly (without putting down the bag). I keep an Xti, Sigma 10-20, and a 28-135 in it. With three lens, you might look into a Nova 3 or 4.

I'm not familiar with other bag designs, but the main flap can get in the way sometimes since the "hinge" of the flap is such that the flap opens towards your body. I haven't found it to be a serious problem yet, though.

If you can, I suggest going into a camera store, putting your gear in some bags, and trying some different styles/sizes before you buy.

Domke is nice. Billingham is better IMO, but more expensive.
Crumpler is okay.

The crumpler 7mdh is kinda bulky, but it works just fine for changing lenses on the go. Only problem is depending on what you keep in the top flap (batteries, chargers, cords) it can become somewhat unruly.

Domke, designed by a PJ so he could shoot fast. For a bag nothing works as well, there are however systems with just lens pouches that might even work better in the field.

I know, I bought mine from BH, but I should have checked Amazon first.

Sometimes shoulder bags can end up being a pain. Here is the backpack that I ordered. I can not tell you haw well it works because it gets here tomorrow but it looks like it is a lot better the the slingshot. With the slingshot you have to take the bag off to get to the lenses unless you realign the dividers and even then you can not access everything.

All you want to do is change lenses easily without placing a bag down, any decent shoulder bag, sling bag or newer type of backpack will do.
My favorite is Domke F-2. I've had it since the early 80s and still be easiest to change lenses while wearing a bag. However, I wouldn't want to carry it on my shoulder more than 30 minutes fully loaded. I use Flipside or Primus for that purpose. Both are backpack type that let you change lenses without putting down the bag. If you are stolling around the park, then Flipside is perfect, it is compact size and carries a lot of camera gear. If you are going to Disneyland with your kids, then Primus will work better, it has fairly decent compartment for extra clothing, snacks and sun block lotion etc.

Domke J-3.

I carry three lenses with me at all times now (in addition to the 40D):
EF-S 17-55 f/2.8 IS (on camera) [with hood]
EF-70-200 F4L [with hood]
EF 100 f/2.8 Macro

Plus flash (580EX-2), wireless triggers, batteries, 5 filters, remote trigger, fullsize rocket blower.
