TZ3 vs ZS3 High ISO

[canon450D]

Hi Found this review for ZS3 tdy

http://www.dcresource.com/reviews/pa...ew/index.shtml

Comparing with DCRP's earlier review of TZ5

http://www.dcresource.com/reviews/pa...mc_tz5-review/

seems IS0 400 for TZ5 has less detail loss than ZS3. ISO 800 also looks better for TZ5. Do you agree? Thank you.

btw title should read as "TZ5 vs ZS3 High ISO"."

But why would you even want to use ISO 400 and above on a compact digicam?

I am interested in ISO400 as that seems to be the setting camera will use in indoor flash shots eg flash photography inside buildings.

That depends on your setting. Unless you use iA mode, you can set the ISO to be used for each shot. With iA mode, you also need to set your max ISO limit otherwise by default it will probably be set to ISO 1600.

Thanks for info. What ISO do you set for indoor flash photography and what is the usual shutter speed that is given? Thank you.

Again it depends. If you use it as fill flash and do not set the min shutter speed, it could go down to 1/2 secs or less. Also you need to see what type of flash mode you use, red eye, red eye slow sync, forced on etc.

In my case, I will usually set min shutter speed to 1/60s and ISO to 200 when taking pics indoors. In this case, even if you select slow sync, the min shutter speed will be 1/60s. This will help you reduce the chance of camera shake and blurry pics.

Think F200EXR should be compared more with Lx3 but think LX3 wouldnt need high iso that much due to its bright lens and good stabilization.

Think the dcresource review does says the ZS3 did btr.
Some quotes below.

There's not much of a difference between the test scene at ISO 80 and 100. There's some of the grainy noise in both shots, but it doesn't really affect the level of detail captured. The PowerShot SX200, on the other hand, tends to smudge away this noise instead. Things don't change much at ISO 200, but at ISO 400 you start to see the Lumix's noise reduction system kick in, but the image retains a lot more detail than the SX200 does at this point (never thought I'd write something like that). Things start to go downhill at ISO 800, with a major drop in color saturation and a noticeable increase in noise. I would save this sensitivity for desperation only. The ISO 1600 shot is missing too much detail (and the color looks awful) to be usable, in my opinion.

The Lumix DMC-ZS3 retains a lot more detail in its photos than past Panasonic models, which is a nice change. Instead of noise reduction smudging away detail, you get the film-like grain in your photos, though unfortunately this is visible at ISO 80. The good news is that this tends to blend away when you print your photos, and you won't notice it in most situations. That doesn't mean that the DMC-ZS3 is immune from noise reduction artifacting: it still smudges details in areas of low contrast, such as the water in this photo. The ZS3 performs well through ISO 400 in good light, and ISO 200 in low light

It's no secret that I really liked last year's Panasonic Lumix DMC-TZ5. Its replacement -- the Lumix DMC-ZS3 (also known as the TZ7) -- is even better, in most respects. I love the new lens and its very versatile focal range, and the Intelligent Auto Mode and face detection functions have been nicely enhanced. And that's on top of the amazing 3-inch LCD, easy-to-use interface, and snappy performance that the ZS3 inherited from the TZ5.

I think it's safe to say that Panasonic is going to sell a lot of Lumix DMC-ZS3 cameras. They've done a nice job improving on the TZ5, though I'm not really sold on the AVCHD Lite codec.

Yes, for F200EXR, widest aperture is only F3.3 which even at ISO800 or ISO1600, the shutter speed is quite slow and may get blur images easily when subject moves.

I am not sure why they reduce the size of the aperture. My previous F50fd has F2.8...

So anyone knows when TZ7 (ZS3) is coming? Kinda looking forward to it's HD video quality for a "weekend" cam....

The TZ15 already has HD video but sound recording in mono.

Yup. Reviews from Cameralabs and DCresource seems to say the new TZ7 video quality is cleaner without visible noise, an improvement over TZ5...

So kinda interested to know how much they have improved...

If it's out, I can at least try out the video quality at places like Courts Tampines...then buy from "reputable" shops later....

Btw how does TZ15 HD video quality compare with camcorder? Thanks.

Definately cannot be compared to Camcorder...

Please pardon my ignorance but in what ways does TZ15 lose out to camcorder for video? Thank you.

The AF is slower and also you have a limit on video length. But it is still a great travel camera..

Panny has even mentioned that GH1 does lose out to camcorders due to b clips or some feature, can't rem exact name.
Camcorders will hav btr compression and sound too esp as Tz15 has only mono sound and mjpeg.

For the same reason why high end camcorders with still pic taking capabilities cannot match even low end PnS digicams in terms of their still pic quality.

In short, camcorder = dedicated equipment to take videos, still pic taking is just an add on.

Similarly digicam = dedicated equipment to take still pics, video taking capabilities is just an add on.

By the way, have u noticed that even a flash based camcorder is still larger and heavier than even a PnS even without batteries??? Especially if you are comparing HD camcorders Vs PnS/Prosumers with HD video capabilities.
