The size weight thing will vary a great deal, but to get similar
performance in terms of overall focal length to what can be done on
a pocket size prosumer, I can't get by with less than 10 or 12
pounds myself.
Oh, I've no doubt about that. My point is... do you
need all the range of focal length? OK, being a pro and shooting assignments, you probably do -- but then, do you need to pack all of it on every shoot?
I'm a fairly experienced and pretty enthusiastic amateur (about 20 years of film under my belt), and very much in the "prosumer digital" or "semi-pro (film) SLR" market segment.
Since I shoot pictures for my own pleasure, I get to pick the kinds of pictures I shoot. I've found that there are three focal lengths I really enjoy: 50 mm, 28 mm, and 85 mm. Or thereabouts. The rest I can dispense with. I take better pictures with primes than with zooms, and I'm not talking about image quality: they make me frame with greater care and put more thoughts into the pictures (if I have the time), and let me seize the moment more spontaneously without the added distraction of the zoom position to consider. Bottom line: I have more fun and the pictures turn out better and more interesting. Furthermore, zooms just don't offer the available-light flexibility I want.

Would it be "possible" to substitute lighter lenses, etc., for this
combination? Possibly - but then I sacrifice the very thing that
the sDLR is being used for - superior quality and versatility.
Or would it be possible to pack a few much lighter primes and modify your shooting style to match? I'd say... possibly.
For a similar focal length range - (actually better) - with my
Nikon CP4500, I have simply the camera, an Xtend-a-View, a small 5x
and a 1.7x tele and a tiny battery charger. With this combination I
get everything from about 8x macro to about 1300mm in focal length
range. Total weight? Way under 2 pounds and fits in a very compact
camera case.
Yep, same goes for my D7i, too.
However... the last time I went traveling, to Lebanon, I packed both my D7i and my AE-1 w. 50 mm. I found myself picking up the AE-1 more often than the D7i, and unsurprisingly most of my favorite pictures from that trip came from it. Sure, the D7i has more zoom range flexibility, but the AE-1 has more Ev and DoF flexibility -- and given a choice, I'd rather have the latter.
IOW, I think it's a bit fallacious to insist that a "fair" comparison between a DSLR and a prosumer covers the same zoom range. Zoom range is a known strong point of prosumer digicams. By giving up some of it, you gain a lot in other departments -- image quality, Ev flexibility, available-light performance, DoF control. Trade-offs, you know. Always trade-offs.
Sure, many people would never think of taking a 70-200 and 100-400
lens and perhaps a 100mm macro with them on a trip - but I wouldn't
leave home without them because I don't want to miss an opportunity
for a once in a lifetime shot simply because I didn't have the
necessary equipment along.
It's funny, but I "see" things differently depending on what kind of camera I have on me. For example, I'd never have considered taking this picture if I'd been packing the D7i (too much dynamic range and timing too critical):
...and I'd never have considered this one, if I'd been packing the AE-1 (too difficult lighting to meter correctly for my skills; not wide enough):
Both are among my favorites from last year... and I wouldn't even have been conscious of missing them if I hadn't had that particular camera with me. Being a pro, you probably see photographs much more easily than I do, but for me, having one type of camera with me limits the field to something I can handle more easily.
I suspect that there are many who just don't' want to have the
bulk, and this is probably why the compact digicams are doing so
well. Obviously price plays an important role here, but as time
goes on, price differentials between dSLR's and compact digicams
will close dramatically.
Yep. However, I think that the same thing is going to happen to digital as happened to film: we have compacts and sub-compacts to the left, at all prices and qualities, SLR's to the right, also at all prices and qualities -- with specialty cameras like ZLR's, MF, view cameras, and rangefinders living in their own little niches.
Most snapshooters will want something pocketable, and most serious amateurs or professionals will want something that performs like a true SLR. I think.
Cheers,
Petteri
