S6000/6500 questions: f-stops and RAW samples

[Tsja]

Hello everyone,

I've got two questions about the S6000fd/S6500fd.

Firstly: How is the f-stop range of 2.8-4.9 distributed over the focal lengths. For instance on my KM 18-70mm f3.5-5.6 it's something like:

18mm: f3.5
19mm: f4
24mm: f4.5
30mm: f5
33mm-70mm: f5.6

This is pretty annoying behaviour and it would be great if on the S6000fd it would be a little evener distribution over the focal lengths. I would be especially interested in the f-stop around the 100m eq and 150 mm eq focal length settings.

Secondly: Is there a place on the net where I can download iso 1600 and iso 3200 samples in RAW format under fluorescent lighting (where I live, typical gymnasium lightning).

This because I'm interested in this camera as a sideline volleyball camera.

It is much more even. It move F/0.1 for every slight turn, evenly going from 2.8-4.9.

From the Aperture priority mode (all maximums f/8):
28 mm - f/2.8+
31 mm - f/2.9+
32 mm - f/3.0+
34 mm - f/3.1+
39 mm - f/3.2+
42 mm - f/3.3+
45 mm - f/3.4+
53 mm - f/3.5+
58 mm - f/3.6+

69 mm - f/3.7+
97 mm - f/3.8+
130 mm - f/3.9+
147 mm - f/4.0+
177 mm - f/4.1+
192 mm - f/4.2+
206 mm - f/4.3+
220 mm - f/4.4+
234 mm - f/4.5+
247 mm - f/4.6+
260 mm - f/4.7+
270 mm - f/4.8+
286 mm - f/4.9+

OK, that's great news.

So with some quick calculations this would work out to be around f3.4 for 100mm eq and 3.8 around 150mm eq. Is this near correct?

This would mean that at the F30's max zoom position (around 100mm eq), the S6000's lens is one full stop faster. That's good news!

Comments on this anyone?

Or RAW's offcourse

Ah, I cross-posted, sorry for that.

Hmmm, it appears that I miscalculated then. So that's about f3.8 for 100mm eq and f4 for 150mm eq.

A little less, but still over 2/3 of a stop more light gathering ability over the F30 at 100mm eq.

Thanks for the input!

Glad to help!

Tnx... I came to the same conclusion ...

The camera will be used for a big part for indoor sports (mostly for web use, fortunatly), so every 2/3 of a stop counts.

Does anyone has some ISO 1600 and/or 3200 RAW files under fluorescent light? I was intriged by the difference showed by DCreviews.com.
