EOS Bodies - For Stills / Re: 5D Mark III at F/8 and smaller Tests
« on: April 02, 2012, 08:43:41 AM »
I had my 135mm f/2 L handy, so I put both TC's on it (F/8) and it had no problem autofocusing about 40 feet away, but it was quite slow.
If this is with 1.4x + 2.0x, wouldn't this result in f/5.6? Can you also try with two 2.0x TC's?

Next, I taped the 70-200mm f/4 L IS and attached the 2X TC (F/8).  I tried it at 70 and 200mm as well.
...
My 70-200mm f/4 L IS was basically unusable with a 1.4X TC.
So you mean unusable with 2.0x TC (and probably also with two 1.4x TC's).

Lenses / Re: How about Sigma 50mm f/1.4 EX DG HS
« on: April 01, 2012, 11:20:45 AM »
My Sigma 85mm f/1.4 is spot on (no MA needed) but my 50mm has front-focussing issues at f/1.4. I set my cameras to +20 but that was not enough, I think it needs about +25. Tried another copy, same issue. I can live with it until I get a Canon 50L although these are still 2,5 times more expensive secondhand than a new Sigma. I definately prefer the Sigma over the Canon f/1.4 I had before because of the bokeh and a better focus ring.
Ferdi, I don't know how aggressively you want to tackle the front-focusing issue. If you want, you can set the camera to +5 and the lens to +20 to get to where you need to be. Then you can put a -5 on the rest of your lenses. Your camera should remember each lens.

Inelegant, but it should work.
The camera (5D2) seems to use only one adjustment option because I can't see any difference between +0/+20 and +20/+20 with the MA-per-lens option active. Likewise, there's no difference between +20/0 and +20/+20 with the global MA option active. Can you tell me how to make this work?

The MTF chart of the II looks better

Some people say the IS has improved a little too.

Some people say the moon is made of green cheese, too.   :P   The optics are identical in both versions.  At least, Canon made no official statement to the contrary, and the size, weight, number of elements and groups, and most importantly, the MTF curves, are identical.  Ok, the MTF curves are not exactly identical, because of an error on Canon's website (honest mistake, or trying to make the lenses look different?) - the 55mm MTF on one is identical to the 250mm MTF on the other, and vice versa.

I didn't even notice that because they are slightly different in size.
So it's all a matter of cosmetic preference. Maybe the resale version of the II is better?

I would return the lens myself. At least settle the price difference, if any (the II is actually slightly cheaper in Holland).

Very nice Dilbert!  Was that with your 70-200mm?
According to the EXIF it's the EF70-300mm f/4-5.6 IS USM on a 5D Mark II.

I'm waiting for the price to drop first, by that time there should be enough reviews for me to reconsider the upgrade. I could also get the 1D X and sell both my 7D and 5D2 but I will probably keep a smaller camera for e.g. street photography. The G1 X might work for that.
In any case, the 24-70L II is higher on my wish list.

About 150g less heavy? That's not too bad, I wonder if they left out the front element again.
I think I'll start saving up for this lens (or just sell my 7D and 17-55), especially if they also fixed (or reduced) the field curvature. But I will wait for the some proper reviews first, and by that time the price might also have dropped a little.

The IS switches are usually below the AF/MF switch (see the primes), and the zoom lock is usually on the other side like in this picture (also compare e.g. the 70-300 IS).

Current 24-70L:


The new one looks a bit like the 16-35L:

(or it might just be the shade of black in the picture)

(...) I was confused how they could call it the tenth generation, when at best you can count  eight separate cameras in the 1D line (including the 1D II N).

As far as I know, these are the 10 generations:

  • Canon F-1
  • Canon New F-1
  • Canon T90
  • Canon EOS-1, 1N and 1N RS
  • Canon EOS-1v
  • Canon EOS-1D and 1Ds
  • Canon EOS-1D Mark II and 1Ds Mark II
  • Canon EOS-1D Mark III and 1Ds Mark III
  • Canon EOS-1D Mark IV
  • Canon EOS-1D X

So yes, the EOS-1 series and the 1v count as a generation.

The 100-400L emits a whirring noise when IS is active.
Can you hear it when half-pressing the shutter button?

To quote the Louvre rules:
Quote
In permanent collection rooms, visitors may take photographs and videos.
However, the use of a flash or any other type of lighting equipment is prohibited.
In temporary exhibition rooms, visitors may not take photographs or videos.
Visitors may not use their cell phone, smoke, consume food or beverages, speak loudly, touch any work of art, or run in any room of the museum.

So if you use your phone to take pictures then make sure flash is turned off.
Be careful not to knock objects over with your backpack, often you have to buy what you break.
Some policemen in tourist areas might get nervous when they see a tripod. Stay friendly and act professional if they ask you to leave or if they think you require a permit (which you only do for making movies as far as I know).

Software & Accessories / Re: Sling Straps: Black Rapid, Sun Sniper
« on: January 31, 2012, 06:04:41 AM »
Any users of the double-strap style ? Wondering how useful, as I just added a second body to my arsenal and have been fairly happy with the single RS-5, but a little annoyed that the phone pocket is too small for an iPhone in a case.
With the double - strap, how does it feel bringing the camera up, c/w with the single (where the strap feels stable ACROSS the chest, but with double, it is coming up more from the side) -- too much swing ??

It does swing more when walking, so make sure to use the front and back straps to stabilize them somewhat.
Also you have watch your balance when switching cameras, especially with heavy combos like 1D + tele prime.
The CoupleR that came with my double strap doesn't fit (I still have to contact them about it), but just using the front strap works fine for me and I am usually stationary anyway.

"It will produce massive dark corners if used on a full frame camera" according to Kurt Munger.
Same for APS-H sensors.
