The dog dragged us to the beach today, Saunton Sands in Devon, UK if you're wondering.

The light was quite unusual.

I use the low pro 600, you can certainly cram in a lot of kit.

but i have been told by a couple of seasoned travelers never to pack the camera attached to a long lens. To reduce the risk of damage to the mounts. You might like to consider this.

If you would like me to test the 200-400 in the case I can let you have my shipping address.  :)

EOS Bodies - For Stills / Re: Just got 5D MK III. What do I check?
« on: January 13, 2014, 05:57:32 PM »
Hi everyone,

I just got a Canon 5D MK III in my hands. What should I check and look out for before the return period expires on me?

Thank you,
Eric

check you know how to use it, you know composition etc, then get out and enjoy. Don't bother looking for problems it'smuch more fun using them rather than looking to try and find a problem, you can catch trollitus infections.

all fine and well.
BUT ... a high-res, high DR, hi-ISO 1Ds III succesor is now overdue by more than a year.
1D X really is only the - very good! - successor to the 1D IV. 

Same situation as the overdue D4x for Nikon. But at least they got a D800E for hi-res, high DR.

Overdue in some peoples opinion, and I expect they want it for p&s money.  ::)

I took this shot today. It had far more resolution than I needed as I had to reduce the size considerably. And I'm happy with how it handled challenging lighting. And it was a grab shot in a hurry as I was limited by not wanting to fly into the flight path of a fast jet.

Some people make do with what they have and can still be creative.

I shoot with a 1Ds MkIII and basically love it but, it has horrible ISO performance and relatively low MP count as compared to Sony's chip in their, and Nikon's, cameras.  I continue to read that Canon has a comparable chip in testing as well as a crop chip, also in testing, that supposedly surpasses anything out there.
So, I ask you...what is the delay???       >:(

What did Sony have at the time of release for the 1ds3?

+1

Are we really comparing a camera from 2007 with cameras from 2012-2013?

and some of us are ignoring the blimming obvious 1Dx that many people manage to take some great pictures with.

Canon General / Re: Are Metal Mounts Better Than Plastic?
« on: January 04, 2014, 06:19:09 PM »

The fibers in carbon fiber components are usually from a cloth so alignment is easy.... It's sort of like with fiberglass.you could lay up fiberglass cloth in a mold or you could use  "chop glass", where short fibers were blown in place.... The chop layup is faster and cheaper, but the laid up cloth is both lighter and stronger.

BTW, we use carbon-fibre dishes in aircraft and on the satellites..... They are far better than metal dishes, particularly with thermal stability and weight.

You won't find may bits in a mass production lens made that way.


Edited to correct typo.

I think that most people will mean the bayonets when they refer to "mounts". It may be that Roger knows better. Maybe people complain when the "mounts" break and from Rogers experience it's what he calls the mount that breaks rather than the bayonet.

On the subject of plastic mounts. Be they bayonets or what the bayonet mounts on. Many will be made of a filled  plastic. That filler may be glass, carbon, ceamic or inert filler as there are several options. It can be in the form of fibers, beads or powder as well as the obvious options of woven material that you probably wouldn't expect in a bayonet, but might well find in a mount as defined by Roger.

There are also several options for the matrix as well. Epoxy is not the most likely for this type of application.

The obvious problem with bayonet mounts for lenses is wear. As the lens is mounted and removed it may well be subject to abrasion. If it wears and the filler is exposed it can create a very abrasive paste or dust that may wear even more, and get in the camera. Thus causing even more wear.

Please don't think I don't like plastic, I'd quite happily buy a lens with "plastic" bayonets. But I wouldn't expect to see them on my 200-400 when I get it. (in my dreams)

Look at the mount on the body, it's metal, but what is it attached to?

Umm, I think you have supplied your own awnser. The Body.  ;D

On my 1Dx that's made of magnesium BTW. But of course its weather sealed and Profesional quality.  ;D

I think your making a perfectly valid point, just couldn't resist the silly reply.

EOS Bodies - For Stills / Re: 5DMkIII AF performance at f/8
« on: December 30, 2013, 05:32:20 PM »
..... Under it is the same image reduced by 1.6x1.6 times the number of pixels (= 750x594) to mimick what would be the effect of going to FF with the same no. of megapixels on the sensor. .....

You are "mimicking" a negative of the "FF", while not making any allowance for the many other differences.

For a valid comparison I would recommend that you use images for the systems you attempt to compare.

from what I see there's no inexpensive way to get cracking shots at long focal lengths on a budget.



I think you will find that's pretty accurate.


Of course some people will not agree, but that's the interweb thingy for you.

I would suggest that you are better off sticking to the 7D with the 100-400 rather than shooting with the FF + 100-400 + 1.4TC.

I tried this combo and it worked reasonably in good light. That said, if you are looking for pixel level sharpness, forget it. Also, if you are shooting birds in the trees, you lose AF, hit a max aperture of f/8 and in dark foliage, are at ever increasing ISOs to render the images unusable.

Personally, I would prefer to use the extenders only with a f/2.8 or a f/4 lens.

I never used the 1.4 with the 100-400, in fact I never used the 1. with the 7D much. It just never worked much for me.

I do use the 100-400 with the 5D3 and find it better than with the 7D. I certainly don't miss the "crop factor", its so much better I get more detail anyway. I also use that lens with the 1Dx and while its not top quality its a great versatile lens.

EOS Bodies - For Stills / Re: 1DX Battery Issue?
« on: December 19, 2013, 01:09:54 PM »
Sounds like very strange behaviour. If it keeps doing this you might like to send it back for checking.

Looking at you post last month, you don't have much luck with batteries do you.

1D X Sample Images / Re: Any Thing shot with a 1Dx
« on: December 15, 2013, 03:31:56 PM »
I was going to Post this Image in the "Bird Portraits" section, after all, it is a BIF.

Except in this case it's a Baboon in Flight, similar, but different.

1Dx 400f/2.8, Shot @ f/2.8 & 1/5000th ISO200

Great image!

Very well caught.

I start with the assumption that Canon know a lot more about making cameras than I do.

That's the spirit, I'll remember to nominate you for the "Canon compliance of the year" award :-p ... but you're correct, not every design decision is "crippling", but as it happens this one is different because ML has proven that auto iso with flash is no problem at all - you can use other iso settings manually, so there is really no reason why the camera shouldn't be able to select the iso according to the ambient light as usual and then let ettl decide the rest.

You mean as my 1Dx does, as I just pointed out.  ;D

I guess your 1Dx is different from my 1D X.   ;)

The issue at hand is when a Speedlite is attached, Canon cameras default to ISO 400 when they are set to Auto ISO.  Are you saying your camera does something different?

I'm not sure if mine is diferent to yours? Send me yours so I can carry out some tests if you like.  :)

I use a 580ex11 on camera or on an extension lead., and most of the time it defaults to ISO400. But sometimes it goes to ISO6400. The manual indicates that it will go to ISO1600. I freely admit I'm out of my depth with flash. I hardly ever use it and find it a bit of a black art. Why the owl shot I put in this tread was at ISO1600 and the one next to it was at ISO400 I have no idea. There is a color cast to the owl so maybe the flash was overheating?

I wrote another topic about this, but here is my observation:

I've find a cool way to use safety shift in 5D. If you use Tv mode and safety shift (ISO), camera will use as high ISO as needed. It actually works identically w/wo flash.

The best thing is that you can use autoISO or set ISO manually. If you set ISO manually, consider your setting as a minimum ISO setting, camera will rise it anyways when needed. This is very nice feature in low light, where fill flash is needed. You can, for example, set high ISO to have f2-2.8, but when it gets darker, f1.2-1.8 are used and if that is not enough, ISO will be risen even more.

That's interesting. I will see if I can use it.

Here's one I took earlier.  ;D  its ISO 1600. and 100% crop, NO PP in LR4, NO NR, NO sharpening etc etc.
