Errr.... sounds like the four poster bed in a Bridal Suite to me  ;)

My 24-105 sounds worse than that if I listen closely !

1D X Sample Images / Re: Any Thing shot with a 1Dx

beautiful eldar,i really have to tour my own country lol
It often takes a foreigner to show how nice home is ;)

HereĀ“s one from the Stonehaven port on the east coast of Scotland, also with the 21mm Zeiss.

I have mostly been shooting birds and animals lately, interrupted by the occasional portrait and event. Wide angle landscape shooting turned out to be a lot more difficult than I remembered (I have tried becoming a photographer for only 40 years ... ::)).

Nice shot of Stonehaven. Really like the one looking down the coast towards the castle too. The killer with wide angle on 1.5 x 1 format is too much uninteresting foreground / sky, but in this shot the grass and rocky beach lead in well from the bottom of the picture, and the sky is good.

See you had typical British summer weather !

P mode can be used as a modified Av mode, in that you can still override the aperture setting and also compensate. Used this way it can be useful. So it's not as much for 'losers' as you might at first think.  ;)

Help me out here - why wouldn't I just use Av mode?  I mean, assuming I'm not Ken "The P stands for Professional!" Rockwell.

Fair question; PBD has covered much in his post above. P allows you to operate broadly as Av, taking control of aperture and iso with a variation on EC. However P will revert back to a 'middle ground' ss/ap balance as soon as the camera is idle. Depending on your situation this may or may not be an advantage in a swiftly changing environment such as parts of a wedding - except when you put a flash on the camera you loose this control. I'm not sure how someone shooting a wedding in P mode deals with this.

The one mode I have never used on digital is Tv. In the film days when you had a certain ISO loaded you might want to have the ss locked. However since digital and immediate access to ISO variation I find it is much better to ensure the ISO is suitable to allow the ss I require at the appropriate aperture. DoF is always important, shallow or deep depending upon the result you want, so to be quite honest I personally have more use for P mode in a modern camera than Tv.

As unfocused says, green box is useful when handing a customised camera to someone to use. If I hand my camera to my wife I put it in green box mode.

For myself, with the exception of shooting panoramics, by far the most used mode is Av. I even use Av when working from a hand held incident light meter reading. Set the required aperture then compensate to shoot at the incident meter reading. If I am trying to nail an exposure and 'picture style' in camera when shooting around 500 images at an event, this saves so much time in post.

So, for example, is you never use P mode - cause you're not a loser ;) - you can take it out of the rotation.

Not sure this is good advice. It depends on shooting style and priorities. I personally wouldn't look at the 6d as an upgrade at all. Slower sync time and maximum speed would be way more important to me than any more or less useful high ISO figures.

I am puzzled by people's concern with the one sixth stop lower flash sync on the 6D. Firstly one sixth difference is irrelevant anyway, but more so because secondly we have access to hss anyway, and if you use one of the powerful speedlites you can hss bounce flash with ease. I have mine permanently on hss; if shutter speed is below 1/200 ( or 1/180) then it automatically uses normal flash anyway.

Also although the AF on the 6D 'reads' the same as the 5D mark one and two it is more precise and positive. There is some significant difference between the 6D and the 5DII. I'm not sure of the technical details but the 6D will lock with a single movement when the 5DII hunt for a split second.

Ignoring the obvious  differences between eight years of tech, the original 5D is still relevant at ISO 100-400. Even 50, where the overexposue by 1 stop reduced works well on the mki.

The big difference is in tonal gradients / transition. Here the 6D is excetionally smooth and film like, and the 5D is relatively harsh. This is even more noticeable in Ooc jpegs whereas the Ooc jpegs from the 6D are really good.

The answer lies in what ISO is...and isn't.  Many people have a poor understanding of ISO, incorrectly assuming that a given ISO setting means a fixed amount of gain applied to the signal.  ISO is a standard (that's the 'S' in ISO, ISO 12232 is the relevant standard in this case), and that standard effectively means that for a given exposure setting in terms of aperture and shutter speed, the resulting image will have a defined brightness.  How does an image taken at f/2, 1/100 s, ISO 200 on a PowerShot S100 have the same brightness as an image at f/2, 1/100 s, ISO 200 on a FF sensor, even though the FF sensor is over 20 times larger?  More amplification (gain) must be applied to the lower total signal from the smaller sensor. More amplification means more noise.  Obviously, the same is true for m4/3 and APS-C relative to FF, to a progressively lesser degree.  Likewise, a medium format sensor needs less amplification than a FF sensor to achieve the necessary brightness for a given ISO according to the standard, and therefore has less noise than FF.

Interesting. So how did ISO work with film ? Was 50 ISO 120 roll film a different emulsion to 50 ISO 35mm ? How did 645 framing on 120 expose the same as 6x7 or even 6x9 ?

Canon EF Zoom Lenses / Re: Canon EF 24-105mm f/4L IS USM

One of the many disused, ghost railway lines in England, closed during the so called 'Beeching's Axe'. They are now incredibly beautiful areas; there is a film of the last train running taken from just to the left of this shot, and the landscape is totally open and unappealing.

This was exposed using my trusty old Weston Master V incident light meter, which actually belonged to my father. I shoot in both raw and jpeg, but by nailing the exposure exactly there was nothing I wanted to do in post with the in-camera jpeg, and this is it.

(I've just had to re post this pic to CR darker. The site seems to be displaying pictures too light. Anyone else finding this ?)

Sella ! Since selling most of your Canon gear and saying 'bye' you're spending more time posting on CR !

A 6D is only a few clicks away. Return that Fuji XT500 and get into a thoroughly modern FF camera. You won't be disappointed.

With all of the flame wars of late, I think we should have one thread to battle it all out for ultimate CR forum superiority.  There's only two rules - try to back up what you say with evidence or examples, and nothing so bad that you get the thread locked...   I'll start things off:

1. Are 18 Megapixels enough?

2. Why do we need more than 12 stops of DR?

3. What ISO setting will we need to take pictures on a new moon night?  Do we really need anything better than the 1D X / 6D?

4. When will mirrorless camera take over?  Bonus: When will they pass the Turing test???

5. Assuming Sony, Nikon, or Fuji had the same lens selection as Canon, and money was no issue, would you switch? Why?

6. Is IS necessary on wide angle lenses?  Do you even use IS on your lenses?

7. What's better, USM or STM?

8. Should DSLRs have video or is just a waste of R&D & money?

9. Is DxOMark THE authority on lens and sensor measurements?

1. Depends

2. Because some of us have the intelligence of a retarded banana and can't expose correctly.

3. 100 - on a Nikon D800. Then lift exposure by ten stops.

4. After Buttercup willingly marries Humperdinck.

5. What do you mean ? Money is no object !

6. Definitely, because I'm a shaky old git, especially when photographing wide bridesmaids getting dressed in a confined space.

7. USM because STM sounds like a sexually transmitted disease.

8. Definitely have it, or we would miss out on the 'oooh', 'arrr' moment when we first have the camera and try it - the once.

9. No ! ( Even if I was a closet DxO fan I would still say NO so people would know I wasn't crazy).

10. Why is there no 10 ? The Op clearly doesn't think in decimal.

103
Is it around now that the Great Crested Grebe will make an appearance ?

First L for me was my 100-400L.  Fell in love with it and signed up almost immediately for my next; 70-200 f/2.8L IS II.  Still have those first two, the others seem to keep coming and keep going from my modest corral..  ;D

@Ken, have you been on the wacky backy again ? This is the 'Best Landscape' thread !

Here's one of mine of Hardraw Beck in the Yorkshire Dales. All you CR guys who can't / won't shoot at anything other than wide open have got me thinking about shallow dof landscapes !
