R6/TZ3 ISO 400 and 800 tests

Thought I'd start a new thread for these comparison shots as the other thread is getting a bit long, plus there is no longer any dilemma as I'm keeping both cameras.

Brian wrote about the unacceptable TZ3 colour bleed above ISO 200 and wanted to see some ISO 400 shots, so here they are. As the weather wasn't up to much today I've taken indoor pics of colourful objects. Not quite up to dpreview standards, especially as I haven't got a clue how to stitch two photos together side by side! R6 pics first.

A crop of the R6 ISO 400:

And of the TZ3 ISO 400:

R6 cropped further:

TZ3 cropped further:

As these turned out so well, I thought I'd try the same thing at ISO 800.

R6:

TZ3:

Cropped R6 ISO 800:

Cropped TZ3 ISO 800:

A further crop of R6 ISO 800:

And a further crop of the TZ3 at ISO 800:

I'm not sure what colour bleed looks like. All I can see is that the R6 shots are much noisier. The TZ3 results are, in my opinion much better.

Re: R6/TZ3 ISO 400 and 800 tests

Thanks Lindy

Although the noise levels look about the same to me, there is clealy red colour bleed at higher ISO which is easily seen on the red edge band around the cat sign.

I would have to say though that I don't think it would be visible in prints, and as I don't use high ISO much myself then I don't think it is a real problem for me.

Lindy,

Great subject matter. Does the cat get hot chocolate as well?

Yes those results look pretty good. I don't think I need to fret about 6x4's.

Perhap the reason those look good is because maybe you had reasonable light. Someone is bound to ask what the shutter speeds were and then request low light ISO400. But I am happy with those results.

Thanks for the test. Don't tell anyone, but I've just ordered a TZ3 to check out the LCD - got 7 days grace, hope the sun shines.

PS. Re your disappointment with the USB speed. You can buy a Hi-speed card reader for less than £10.

The black outline at barts head and the lightblue of maggies dress is bleeding into the orange background.

Re: R6/TZ3 ISO 400 and 800 tests

The biggest difference I can spot is the cat on the first crop of the TZ3 @ ISO 400 shot. Compare it to the same shot from the R6 and I think you can begin to see the 'watercolour' effect that is often commented on with the Panasonics. As I understand it, It's a result of the noise reduction on the Pannys i.e. the detail gets smeared along with the colour saturation being reduced a bit.

I'm not saying it's unacceptable, just noticeable (on the cat at least).

Re: R6/TZ3 ISO 400 and 800 tests

so maybe you, linda could make those comparison shots of something with a fine texture like fur or so?

Believe it or not, his favourite food is curry, closely followed by anything with lots of garlic. Oh, and he has a very sweet tooth and adores cheesecake. Getting him to eat cat food can be a real trial!

I think they're really good. I'm very impressed with the TZ3.

They'd better not It's time I took some real photos.

That's great! Let us know how you get on.

I've already got one, but it's such a faff to take the card out of the camera and put it in the reader and then put it back. I might as well just sit here staring at the screen twiddling my thumbs - oh sorry, that's a man thing

No problem Brian. Glad I caught you before you leave for NZ.

clealy red colour bleed at higher ISO which is easily seen on the

The noise levels don't look the same to me. The R6 shots look noisier. Now you've pointed it out, I can see the colour bleed on the TZ3. This doesn't bother me. Noise does.

I would have to say though that I don't think it would be visible
in prints, and as I don't use high ISO much myself then I don't
think it is a real problem for me.

Do you think the Venus III has improved or not?

Hi Andy,

Yes, I can see that now you've pointed it out. I still think, generally speaking, that the TZ3 shots are better. It's probably because I dislike noise so much. To me the R6 shots are much noisier.

Re: R6/TZ3 ISO 400 and 800 tests

Im getting my R6 on Monday : ). Its my second digi ever now that my old konica KZ 400D from 2002 has done its time. Just hope the R6 is much better. I agree that the TZ3 has less noise but there is something i just like about the R6 pictures over the Pannys. Dont really know what it is. The noise i dont think is a bigg problem for average users on smaller prints.

Do you mean like the fur of an animal? I have a picture of my cat taken with the TZ3 at ISO 800. If you need the R6 as well I'll try to take some tomorrow. It's not easy getting him to keep still though!

Re: R6/TZ3 ISO 400 and 800 tests

Yes, fur like in animal fur...

But it would be more helpful is you could manage to get a comparison like the one aboveand crop the photos to 100%.
Kind of a still life with some fine texture (like fur).
So we can see the smearing better.

Thank you. His name is Micky.

... perhaps in future you shouldn't compliment an English woman on her pussy. Her husband might get quite the wrong idea!

Anyway, I'll try to get the fur pictures you've requested.

oh, sorry.
as pressed "post" i knew there was something ambivalent but it was to late.
You know...ambivalent as in "pussy galore", a character in a bond movie.
i didnt mean that.

nice CAT...

could you please make the requested comparison shots?
thanks.

Re: R6/TZ3 ISO 400 and 800 tests

Lindy,

Great work - really interesting comparison. Obviously there is a lot of room for subjective preference here, but after initially preferring the TZ3 images I find that the longer I look at them the more I prefer the r6. I displayed the pictures side by side on a large monitor to compare them, and even from quite a few feet away the color bleed is noticeable on the TZ3 images. To me the noise in each image looks about the same, but the R6 is obviously a much "softer" image. Just out of interest, what do you have your r6 "sharpness" set to - sharp, normal or soft?

Ross.

Re: R6/TZ3 ISO 400 and 800 tests

Maybe it's just me, but the R6 ISO 400 shot seems grainier than the ISO 800 shot. Is there some kind of NR going on starting at 800? Is there a way to turn the NR off?

The R6 is grainier that the Panny, but I prefer it that way. Seems more tactile. I remember there were concerns expressed earlier about the so-called "smoothing" engine of the R6 versus the R4. Can anybody say whether there is a big difference in IQ and grain?

Hi Ross,

Thanks for your comments. The test took quite a while and it's good to know my efforts are appreciated.

The R6 was set to Normal sharpness. There is no sharpness setting on the TZ3. I set the colour to Standard. I believe that the colour setting on the TZ3 affects sharpness too. From what I've read it would seem the Natural colour setting processes images the least.

The ISO 400 shot looks grainier to me too. I have no idea why. As far as I'm aware, there isn't a way to turn NR off.

Having had the R4, my opinion is that the R6 does smooth more than the R4 did. We need someone who has both cameras to confirm this.

That's OK. My husband and I had a good laugh over it.
