EOS Bodies / Re: Canon 5d Mark III Shadow recovery

@sdsr, you've got to the nub of the matter; to really try and prove the benefit of lifting under exposure on the exmor sensor these guys are having to go to extremes. Something that poor old TrumpetPower has been trying to point out until he's turned purple.

Most of us know that the Nikon has less noise/ banding etc when you really push it, but when it comes to producing real pictures the benefit is much less noticeable - unless you're main pleasure from digital photography is lifting under exposed data to mid tones and viewing it at 200%.

By 'old' and under £100 I presume you're referring to AiS manual lenses. Not sure if the D40 has the manual aperture finder required. Seem to remember you had to go more up Market to get this feature, but may be wrong

@sach100,

Thanks for that, much appreciated.

We try to shoot in dramatic light so do a lot of shadow / low lights recovery. As you have found, there's no problem in practical application.

Darn 

Imagine if we had shot this on a D800 instead of out dated gear from 2005

I did a series last night using an ND64x while standing out on a (still) frozen river.  I am slowly building up filters in the 82mm and am considering whether to move some of my 77mm filters and just use a step up ring.  Anyway, this shot is the result of three bracketed exposures hand-blended using luminosity masks.

Ah, and all this time I thought people were doing it purposely to show their appreciation of the 50mm f1.2 (or 85mm f1.

EOS Bodies - For Stills / Re: Can anyone explain what on Earth DXOMark is on about?

Since I had +1 on Sporgon's post, I feel I should mention it - I think you've read Sporgon's post in a hurry. he was not speaking of his own assumptions but was being humorous with respect to another poster who had found the DXOMark article "disturbing" and has had a rather large axe to grind on these forums lately.

Fair enough - I should have stated 'false assumptions' rather than 'your false assumptions'. Sorry about that!

That's OK. If I may quote Benedick from 'Much Ado About Nothing'

"In a false quarrel there is no true valour"

I'm curious...what is disturbing about the way the results are presented?  Are you equally 'disturbed' by their presentation of the results that show 14.4 stops of DR for the D800? 

I would think that what he finds disturbing is the fact that DXO rate the D800 sensor much higher than the 5D, but then say;

" 'half a mo, when we put a lens on it we're not so sure".......

Case in point - lenses. The scores are weighted in favour of faster lenses - 'transmission' - but a f1.4 lens is not necessarily better than a f2.8 one in practice. 'Transmission' is a moot point in still photography at best.

But in this case (the referenced article), your point is irrelevant because they're using their P-mpix value, their measure of sharpness.

OK, well perhaps it would be more relevant to suggest that this test may have been prompted by Roger at Lens Rental's comparison between the D800 and 5D with various standard zooms - reported here on CR.

Anyway, within sensors of the same size, would you not expect one with  larger pixels to exhibit greater per pixel sharpness than one with much smaller pixels, all else being equal ?

Maybe they have come to realise that they are leaving the real world behind.

Obviously a lot of work goes into their 'testing', but they don't do themselves any favours IMO, from lumping contradictory factors together and producing an 'average' score.

Site Information / Re: Love or Hate Canon Rumors Forum

« on: April 05, 2013, 06:22:23 AM »

I followed CR for some time as a rumour site, and found it interesting. Began to read some of the forum posts and found that unlike other forum 'discussions' that I had come across CR seemed to be populated, on the whole, by intelligent, courteous people who either knew their stuff or were a sponge to receive the information.

Also many of the photos posted were ( and are ) superb. So I joined and it's the only forum I have ever been involved in.

Inevitably you get a few of the aggressive 'forum speak' posters who can be insulting whilst hiding behind anonymity, but they are generally few and far between.

With regard to the continual resurfacing of topics such as ( the dreaded ) DR, despite the often inane postings by troubled souls, there is some really good information that can be gleaned, such as the fact that Canon sensors respond better to over exposing slightly if the EV range allows. So even the latest rant on the subject was not totally in vain.

The more aggressively a poster puts his view across the less likely it is to hold any substance, so it's often easy to avoid following Red Herrings.

I also enjoy the truly global scope of the forum - it's not so much it's a small world, it's just we move in small circles

Sell both and get 24-70 f2.8 II

The OP's question was 'any difference between used and new 24-105'.

The scene is irrelevant; it's all about the light. Great light in a junkyard will make for awesome art. Bad light in formal gardens will generally make for bad art, unless you work with it to paint a picture of contrasts. And trying to shoot anything in bad light but make it look like good light?

Ok. Define "bad light" then.

Why do people put diffusers on flash guns ? After all it's just light.

Yes you can see why Canon hasn't rushed out a 40 mp body.

Anyone who has really maximised their 18 or 22 mp know how remarkable that degree of resolution can be.
