E3 Better Than D3?

I enjoyed writing this rather tongue-in-cheek piece, pricipally to stimulate debate on "Talk Photography," but I thought you might enjoy it here.

Are there any circumstances where an Olympus E3 might out-perform a Nikon D3 in terms of image quality? My first reaction to this idle thought was, “No, surely not,” but then.......take this scenario:-

Two aspiring wildlife photographers, One the owner of a D3, the other an E3, need the longest reach lens they can get for less than £1000 and both settle on a Sigma Bigma. It has, of course, a maximum focal length of 500mm regardless of which camera it is used on. However, the Nikon is full frame and hence has no crop factor whereas the Olympus has a x2 crop factor that creates an angle of view equivalent to a 1000mm lens on full frame.

Now it just so happens that both photographers have a particular interest in wild birds and need every millimetre of focal length they can muster, ideally at least 1000mm or equivalent. The E3 owner shoots away happily, filling the frame with his subject and producing detailed 10MP images that require no cropping. The D3 owner gets the same images, except that the subject is much smaller in relation to the size of the frame and the crop needed to match the E3 magnification results in 3MP (yes, 3MP) images. Now I've no doubt that they will be very high quality 3MP files, but can they really match the 10MP files from the E3?

Of course, the Nikon owner can always add a x2 converter to match the effective focal length of the Bigma on the E3, but his lens will now have a maximum aperture of around f13. The light levels are quite low and the Olympus owner is shooting 1/250 sec @f6.3, ISO 400. he is comfortable using that comparatively slow shutter speed on such a long lens thanks to in-body IS. The Nikon owner can thankfully crank the ISO right up by virtue of the superb noise control of the D3. Without the benefit of IS, he is wisely shooting 1/1000 sec @f13 with the ISO set at 6400.

Thankfully, the brilliant sensor of the D3 is quite capable of supporting ISO of this magnitude but is this situation getting to the stage where the seemingly inferior E3 has the edge? Don't forget the Bigma is now attached to a x2 converter and even the best of these is bound to degrade IQ slightly, especially when shooting wide open.

The sky darkens and the EV drops another two stops. The Olympus owner wisely won't go slower than 1/125 sec for fear of subject movement, meaning he has to step up to ISO 800 – at which the E3 still performs surprisingly well despite the negative press it has received for high ISO performance. Meanwhile, the Nikon owner is forced to make rather more serious compromises. It's not ideal without IS, but he drops his shutter speed to 1/500 sec and cranks up the ISO to 12800. Now it's truly amazing that the D3 can produce an image at all at this sensitivity, but can it really compare to the E3 which is still cruising at ISO 800?

Food for thought?

John,

That's brilliant. As they say many a true word spoken in jest... Can you post a link to the replies you get on this.

A little while back, I did this as a test of just how far you can reach out, when push comes to shove and you simply have to get the shot.

This was done with an E-500 with a Sigma 600mm + 1.4 converter will give you 1680mm



Go nuts and add another 2x and you have 3360mm



Both shot at 1/60th ISO 400

Can't wait to see what I can do with an IS body.

Of course this is very valid for telephoto photography but not for anything else where the D3 would win every time I guess.
Although not related to IQ the fatigue experienced by the Nikon user (due to all that heavy kit) would likely mean that they may not be able to keep shooting as long as the E-3 user and would therefore end up with fewer images. Oh, the joys of lighter kit!

Re: E3 Better Than D3?

Well what it tells me, which I already believed, is that different cameras have different advantages (and indeed disadvantages).

The sad thing is that most reviewing, in order to be comparable, uses a standard set of metrics and tests. And then, worst of all, comes to a conclusion that 'rates' the camera against its rivals. Just because a camera is 'good' for one application, does not necessarily make it better for all.

Reminds me of the old example I used to use when I delivered 'Quality' training (not original - nearly everybody used it). Which is the better car, the mini or the Rolls-Royce, well for everyday use driving yourself around then the mini might well be considered better (economy, parking, maintenance etc); which is the better car, well perhaps the Rolls-Royce (materials, construction, comfort etc). What then is 'quality' and which has it?, isn't it dependant on what you require, what measurement criteria relate to your specific needs?.
