[line] I like its manual controls, 4x zoom, Leica lens & 8 MP

But don't like the native 16:9.

I am an advocate of "normal" 4:3, and 6MP is adequate for me.

Pana's spec says if set 4:3, it will be downgraded to 5.5MP. My silly maths below shows too much loss:

Ratio 4:3 = 12:9,
=> usable pixels = 12/16 x 8mp = 6MP
=> 0.5MP more loss than theory.

(my guess the CCD is not exactly 8MP or not exactly 16:9)


The loss in wide-angle is rather acceptable:
28mm x 16/12 ~ 37
as compared with Pana's spec of 38mm at 4:3.

Would some tall people in this forum shed me some light if the LX-1 is worth if I use it for 4:3?

What other features will I loose by using 4:3?

Thx!

What I see on Panasonic's web site is different thatn what I see in your posting.

http://panasonic.co.jp/pavc/global/lumix/lx1/index.html

I believe the MP count changes from 8.4 to 7 to 6 as you go from 16:9 to 3:2 to 4:3. The exact pixel dimensions at each resolution are on the site above so you can check their math if you want.

I can't think of a good reason to buy this camera if you only use 4:3. Panasonic, Nikon, Sony, and others make good 4:3 cameras of the similar size and megapixellage. From the sample LX1 photos I've seen it's no better than these other cameras.

Up to now Panasonic LCDs haven't been great in direct sunlight. I would want to get my hands on one and take it into direct sunlight before deciding on a camera without a viewfinder. I would also want to make sure it gains up properly in very low light – another thing Panasonic hasn't been very good with up to now.

Some people are saying the wide ratio is the thing of the future. It will display well on a HDTV and look good on the new wide monitors. I personally think it is inefficient. They could have made a 4:3 with the same pixel density and with the same lens and f capability with much higher pixels. You would end up with 8Mp if you shot in HDTV mode and probably 10Mp in 4:3.

Thanks Bruce for reminder about the official Pana spec!

I got the figures: 5.5MP & 38mm, from just a local photo magazine.

Yes, I agree with Slipe that 16:9 is inefficient. I just can't imagine if a 9:16 portrait (vs landscape) picture would look like a long roll of Chinese water color painting ???

I think they should provide 16:9 AS AN OPTION for a normal 4:3 DC (like my current Kodak V550), instead of the other way round as in LX-1.

Struggling with LX-1 because the rest of the features (not the quality which I haven't seen) are so attractive as I put above.

Here's Panasonic's FX 8 and 9 line, that have native 4:3 with 16:9 as an option. The 9 has an extra megapixel or two.

And here's some sample images of the LX1.

I may actually get the LX1, I will use 3:2 most of the time but I do make a fair amount of panoramas and will certainly continue to do so. I'm a little concerned about the picture quality of the LX1, particularly the noise.
