When you compare the f/2.8 LEICA DC VARIO-ELMARIT 12x optical zoom lense to what comes in most of the DSLR kits it starts looking very good.

Ignore whatever jargon manufactures tag on to their lens. It may have a Leica badge, but then again, I don't think Leica were ever famous for their zoom lenses. The large F/2.8 aperture is good, though. Also, I would want to look into the focus speed of the DMC-FZ50. It's insanely annoying when the focus hunts back and forwards for a second or two before it 'locks'. Combine that with a shutter lag and you'll find yourself missing shots. Since the FZ50 is one of the better "point 'n shoots", it may not be so terrible.
DSLRs tend to focus much quicker, but I have encountered at least one which isn't quite up to scratch: Pentax K10D. I was shooting with one last night (w/ 50/1.7) and the focus hunts quite a bit.
Another area where DSLRs would be superior is metering accuracy. Quite a few DSLRs have very sophisticated metering systems. The latest and greatest Nikons have thousand-pixel sensors that meter pretty much across the whole frame. Even the size of the center-weighted point can be adjusted

I don't see myself having the budget to buy a comparible lense or a slew of lenses to form that kind of range for a DSLR any time soon.I've been comparing the specs of the D40 to the DMC-FZ50k and they have the same ISO sensitivity ranges. Is there really *that* big of a difference between a 10MP 1/1.8" CCD and a 6MP DX format CCD? |
The DX format CCD/CMOS is
much larger: 15.8 x 23.6mm. The 1/1.8" CCD is only 5.3 x 7.2mm. While there is a lot more to a sensor than just size, the size of each photo-diode/sensor/pixel generally determines how much noise there is in picture, ie larger photodiode = higher S/N ratio.
On a DX/APS-C CMOS sensor like the one on my D300, I will be able to achieve cleaner pictures (higher S/N ratio) at ISO1600 (or even 3200 if the exposure is perfect) than a FZ50 at 400. That's at least three times as much light with the same aperture and shutter speed. On a full frame/FX CMOS sensor like the one in the D700/D3, the performance is even more insane: ISO 6400 looks better than ISO 2000/3200 on my D300.

Haha. It was totally subconscious, and I wouldn't even claim to be any good at mathematics!

We have to be careful though. Correct me if I'm wrong, but a F/2.8 on a 1.5 crop sensor is quite a bit more narrow than a F/2.8 on a 2x crop sensor. I'm not sure why this is (it really doesn't make sense to me yet), but that's what I've been told. Actually, the more that I think about it, perhaps it does make sense. |
I have read that too, but honestly, it doesn't make a difference to my shooting so I haven't really bothered trying to understand this 'phenomenon'.

In most instances, yes. In a wedding, no. Lighting is often poor or mediocre, getting the best shots is often a matter of timing and being able to get stuff done quick (which means no AF hunting or slow shutter speeds causing subject blur), and, most importantly of all, you only get one chance.
... Fast glass and a decent flash setup are a must.

In fact, the newest Nikon pro glass - eg 24-70/2.8 - focusses even faster than my 50/1.4 AF-D!

RE: DMC-FZ50k
Turns out that you only get maybe 350 pictures with the LCD on per charge, so that's a big difference. Also, I'm wondering if the 2" screen is going to be big enough... though the ability to reorient the screen looks usefull.
*sigh*

Screen size is not as important as screen resolution. 350 pictures per charge is pretty poor though
Is that with flash? I was just at a wedding the other day and I shot 380~ (RAW+JPEG) photos, all flashed (some +EV compensated) with a lot of viewing in between. My battery was around half way.
