Why V7 is better than V8??

In terms of image quality, V7 is much better than V8. But why??

Please look at these sample photos of the same objects, taken with V7 and V8.

EX-V7 ISO1600

EX-V8 ISO1600

V7's photo looks better and is much less noisy.

I was considering buying V8, but after looking at these photos,, well, should I buy V7???

1) The noise difference in the pictures are very small in my opinion.

2) 1/2.5" Sensors (like V7/V8) have noise problems at ISO above 200 and should be very similar, the only real difference between cameras with those sensors are between the noise reduction algorithm used in the post processing.

3) The V7/V8 by default do not use more than ISO200 so ISO1600 pictures are meaningless.

In my opinion the noise difference between the V7/V8 are so small so you could ignore it.

The main difference, is probably the more default in-camera sharpening that the V8 has, the noise in that image, atleast at 100% does look marginally worse than V7. I am suprised how much image detail is kept though, as that bunny is still, considering the circumstances, fairly detailed.

1) But V8's picture looks a little bit purple in the background, while V7's background looks black. And black is the real colour. V8 has more colour noise. But maybe you're right, these are small difference.

2) When I look at many samples on the internet, V7's ISO 800 or even 1600 is still acceptable. It looks better than my current camera's ISO 400.

Post processing is important. Did Casio changed the NR algorithm? I prefer the algorithm in V7 than V8 for the high ISO.

3) True, but sometimes I use ISO 800 at least. But, considering other uppgraded features, should I still chose V8.

It is possible that the higher noise in the V8 is due to the higher mp for the same sensor size.

I guess so too. But the V8's colour is different from V7 at high ISO. V8 looks more purple. Now I have realized that I could alter the colour on PC. And now V8 looks much better after I changed the colour less purple. Ohh, I should definately buy V8.

Maybe. Just now I realized that I could change the colour, and reduce the purple-ness. Then, V8 picture looks much better. So I decided to buy V8.

Tell us how it turns out for you. I still want a V8, but want to see/hear more reviews. BTW, with any camera I've owned (Panasonic FZ5, EX-M2, Z750, Z60), I never used over ISO200, which is the default for most of them anyway... So ISO1600 samples really dont interest me. I'll just use lower ISO, and post-process later if they are underexposed.
