Does anybody know the discount code? I'm struggling to find it in this huge thread
Ignore me, I've just googled it. It's P10FEB15 for anybody else who was wondering.

Your British Museum shot has worked well. I tried the panorma mode when I was at ground level... the central part was OK, but none of the panels in the roof aligned properly. So I took a couple of still then stitched them together in PS Elements instead. It did work on the display of the Elgin Marbles.
I've had some good landscape shots outdoors, but I tried capturing a room of people this week and it would not work for me at all, must have tried 5-6 times.
...Piscator Pete,
Pete, thats a cracking post.
Rhodese.
even though the post was largely about failure!
I know this has been asked before but We're on to 213 pages now so I don't fancy trawling through them
What aperture do you guys recommend for landscapes with the x10? i.e. deep depth of field but very sharp?
I seem to remember people mentioning f/8 being the sharpest of the range, is this right?
Cheers!
Asa,
I, too, would like 'them what knows' to repeat the info about this one, and for the same reason - it's a hefty thread!
The smaller the stop the greater the depth of field and the lesser the effects of lens aberration - all standard stuff; but as I understand it, with the short focus lenses of modern compact cameras, the tiny absolute apertures necessary to achieve even modestly small f-numbers introduce significant loss of definition owing to the diffraction of light accounted for by one Herr Doktor Heisenberg and his 'Uncertainties'! I think it was Duncan who reckoned that the optimal 'trade-off' between aberration/DOF and diffraction, was around f4.5 for the X10 lens. Anyway, acting on this advice, this is my default setting for such shots.
Sorry about the wordiness of the above, but I'm hoping someone will give this an airing, and help the understanding of someone like me, used to old 35mm rangefinder cameras, who for landscapes used to stop down to as much as I could get away with in terms of exposure - diffraction didn't seem to be discussed in the old days.
Pete
Ah, the old 1/50th @ f8 and sunny 16 days!
I still use up to f8 and get nice sharp images. Over that and I start noticing I start to lose detail.

By the way, I see you've 'deserted' us for the X20. Maybe it's my monitor, but the colours I see on that thread seem quite different from those on this. Is this just down to how the camera is used?
Pete
Not deserted, still popping back to see whats going on. I think we should merge the X20 thread, its so similar, apart from the viewfinder and a few bits that are different.....
I dont think there is much of a difference in colours between the two either, I have been comparing my photos and colourwise, they look similar.
Allan
Have a look at pages 20, 68. I use f4 a lot.

Rhodese - many thanks for that; I was just too lazy to search!
I was pondering Allan's reference to our old rule of thumb (with FP3 or similar) of 1/50th at f16 on a sunny day when we couldn't be bothered to use (or didn't have) an exposure meter. Why weren't we bothered by diffraction at such large f-numbers in the 'old days'?
Well, ferreting about in what remains of my memory, I recalled that f-number = focal length/effective lens diameter, or f = F/d, and transposing, d = F/f.
So, for the X10 perhaps being used for a landscape at minimum focal length and f4, d = 7.1/4 = 1.78 mm!
I didn't believe this, and so have just checked my X10, and f4 really does look that tiny! It's only pinhole at f11!
Now for my old Agfa coupled rangefinder job with its 45mm lens and at f16, the calculation becomes d = 45/16 = 2.81 mm.
So there you have it - unless I've made a glaring error - if diffraction with the X10 is no problem when the actual aperture has a diameter of 1.78mm, it was never going to be a problem with our 35mm film jobs even at f16 which only needed effective apertures close to 3mm!
I suspect all this is old hat to most of you, but it really opened my eyes!

I thought the same quite a while ago (post as link) but no one else made comment & Duncan never responded so I let it be. I still wonder if it is the way to go & still to include the XF1 as Nod tells me the 'insides' are the same as the X10 but .....

Thanks for your comments Allan. If the two cameras produce much the same image under the same conditions, I like John think a merger would be sensible.
Pete
In reference to apertures and DOF, X10 v 35mm.
It's took me ages to find it , but I knew "Duncan" had put up a comparison chart for 35mm - X10 . Page 132, post #3933 and post #3946.

...where's all those pictures/questions/ snippets of wisdom?
How do I shoot in sports mode? I've set it in the advanced menu but it doesn't seem to quick fire?
One just to bump the thread, bottom of page three, come on you lot, where's all those pictures/questions/ snippets of wisdom?
Rhodese.
Having read the piece below copied from a 'Duncan link', which Rhodese reminded us of, and which I failed to read right through, my post 6380 on the previous page, 213, is wrong - I had made that "glaring error"! I overlooked the increasing image distances as focal length increases, and any diffraction pattern will increase in size proportionately. Apologies!
''Technical Note: Independence of Focal Length
Since the physical size of an aperture is larger for telephoto lenses (f/4 has a 50 mm diameter at 200 mm, but only a 25 mm diameter at 100 mm), why doesn't the airy disk become smaller? This is because longer focal lengths also cause light to travel further before hitting the camera sensor -- thus increasing the distance over which the airy disk can continue to diverge. The competing effects of larger aperture and longer focal length therefore cancel, leaving only the f-number as being important (which describes focal length relative to aperture size).''
Allan, that then heightens the mystery of why we didn't bother about diffraction in the old days! Perhaps lenses and film grain were so poor, we didn't notice.

The X10 still surprises me, don't think I'll be selling it soon as I stand to lose a few quid already if I did, noticed one sold for £170 a couple of days ago :thumbsdown:
Possibly it's because we didn't have our photos on computers where we can easily zoom in to 100% or more to inspect them in far too much detail. Instead we made a print (often small) and viewed at it from a sensible distance to look at the picture.
Some people spend more time worrying about their pixels than their pictures.
Just my thinking on it.
