Is it time to UPGRADE?

[Colin Southern]

I am sure Canon will hit back with something to top the D4s.

They already have - it's called the 1D X

Actually Colin it sounds like they still haven't caught up.

Surely it aught to have a 90mp sensor to catch up with medium format too.

ISO - just a change in amplifier gain.

Someone should have told Scott Kelby before he jumped ship

Noooo - that's the last thing we need. Besides, Canon have already made a 120MP sensor in an APS-H (1.3x CF) format. That would equate to 175MP in a standard FF size if scaled.

ISO - just a change in amplifier gain.

Only for standard modes - for expanded modes the gain remains constant (at the highest standard mode gain) and they do the rest digitally.

Earlier this week I attended a talk by a well known British photographer called Colin New (see www.colinnew.co.uk ), part of which was a travelogue of Myanmar / Burma and of course had some great images. Of course he was asked if he used a full frame camera. Colin explained that he had found his 5D and L glass too heavy, so he had sold it. On this trip he had carried a pair of 600D's with a medium zoom on one and a long zoom on the other. I left thinking if it's good enough for Colin New, it should be good enough for me. (I happen to have a 600D)

Colin also commented that he found the light in some of the monasteries the trickiest he had found anywhere, so what did he do? Well, he said, there is this thing called auto ISO

It was a good evening

I'd have to say that pretty much the last thing we need is more MP - we already throw away over 95% of what we have now in a typical internet image....

Presumably "we" is intended to indicate some focused group in mind as opposed to the global "we"?

I'm not so sure about that Colin. As you have noticed I have done some "high ISO" work recently. I usually start at the bottom but got the surprise of my life when I took a shot at 25,600 on the E-M5. It was usable at a moderately long exposure. Yet when I tried a more normal high ISO and a fast shutter speed - load of crap. The D7000 seems to be similar. On that 2000 and 1/5000 sec noise not even worth bothering with but did reach mid tone white. Then there is that NEF file I posted where you remarked that there was a fair old dynamic range in it - noise levels crap to the point of making life difficult.

I suspect they are doing a mix of things based on what is sensed. Nothing else makes much sense.

When I look at reviews I still get the impression that Canon win on dark noise and that is what really matters when shooting low ISO. Smaller pixel sized camera are beginning to crop up now with lower ISO setting. Obtained by under exposing.

An earlier comment about small pixels and lower noise density was interesting - have the noise but reduce the size of the image to get rid of it and post it even smaller on the web. May as well have bigger pixels and lower noise.

What is really needed is a new technology. I'm not aware of one.
