Lenses / Re: Rubber Seal 24-70 f2.8 L
« on: April 24, 2013, 02:18:04 PM »
Concern is what. To do with the other places the water can come in. It took my 85L out in the rain once and it rained right through the focus distance window, the mount was dry between camera and back if the lens.

That's the exact problem with stuff like the dust donut - it can only attempt to fix the leak at the lens/body join and does nothing to seal up the rest of the holes in the lens. However, the 24-70 mk I is a weather sealed lens, so all those other potential water ingress points should be covered. Presuming yours only has damage to the rubber gasket at the lens mount, it should work - but as to whether its anywhere near as good as the genuine $211 Canon seal, I couldn't say. And I guess there will be a bit of a wait seeing as it's still at the kickstarter stage.

For now I think I'll just use the 50L for the rainy days . Perhaps even remove the seal as it is pretty chewed up.

Is this one of those rare occasions where a dust donut makes sense?

Thanks I'll look into that. Cool stuff on Kickstarter.t

1.   Call Canon directly.  They will sell parts to owners.  Its best if you have a part number, but they will try to help.

2.   Call a third party authorized distributor like Midwest Camera, Precision Camera, ...

You can Google for Authorized Canon Camera Repair Depot

Thanks a bunch! I'll try those :D

Lenses / Rubber Seal 24-70 f2.8 L
« on: April 24, 2013, 09:30:30 AM »
Hi guys!

Anyone know where I can get the rubber seal that's on the back of the mount of a 24-70mm f2.8 mk1?

I asked my local Canon-shop if they could send me one for me to fix myself, and they could, only it was 211 USD! I tried looking on eBay, but couldn't really find one.

Thanks!

EOS Bodies / Re: 1DX Autofokus did not work when really cold -20 C
« on: April 23, 2013, 02:41:24 AM »
I've used in -20 it's a normal winter temp here, but haven't used like you have spending days only outside, so can't really say something. I have been out for a few hours and the camera was certainly what I would call very very cold, but it worked normal except a bit more resistance when pushing
Buttons and the smaller lcd's responded a little slow. Battery capacity wasn't much to brag about, but we know that is a problem.

IMO though, the AF should work in places WE don't work, so I find that strange.

Third Party Manufacturers / Re: Sigma 18-35 f/1.8 DC?
« on: April 18, 2013, 07:21:42 AM »
Judging from the way other ultra-large-aperture zooms are designed (e.g. the Oly 35-100 f/2) I'd guess that the design is basically a 35-70 f/3.5 with a reversed 2x teleconverter at the back.

I imagine that an FF version of this concept would weigh well north of a kilogram (& cost well north of a kilobuck).

Kudos to Sigma for being innovative once again.  Hopefully this will show C & N that there's real demand for more large-aperture lenses.

I've said this before and I'll say again, do we really mind a 1.4 kg lens that covers 24-70 at f1.8? We carry the 70-200 with that weight with no issues, so why not a 24-70?

Reviews / Re: Review - Sigma 35mm f/1.4 DG HSM

The results from the Sigma do look good; I've never really been an ultra shallow DOF shooter so perhaps that's why I can't think of any situations when you'd be shooting at f1.4 and require critical corner sharpness.

Can someone post a real picture which has razor thin DOF but requires corner resolution ?

you will never get critical corner sharpness at 1,4 but it shows that sigma in this case is much better than canon at 1,4 which not can be bad parameter.

Last pictures regarding the  bokeh issue, to me they are very equal

Well, I will wait to agree with that until after I get
The Zeiss 55  ;D

Here's a quick example shot at 1.2 to show the need for corner sharpness. Aimed at his eyes.

I the same issue, i use a black rapid and when the camera hangs not being used and I lift it too my eye I'm more
Often than not on f22 as I have bumped and turned the top dial. For
Me I have the time to change it back, but to have that happen to two or three cameras in a journalist situation must be the worst. If I come up with a good solution I'll let you know.

Crazy.  Every time I tried it the program would crash and I would have to manually restore my settings.  Maybe I'll uninstall it, reboot, and re-install again.

But it doesnt work with the 5DIII (reikan af algorythm).


Works just fine with my 5D MK III!

Be sure to use the new version, they fixed those crashes now.

I'll cut to the chase here. I think your camera and afma is fine, the 5d3 IS softer than the 5d2. If it is ONLY the AA-filter that makes it so soft your customer notices I'm not sure about. However, if your clients uses their own designers and editors to work the picture before a release of a magazine for example, I can easily see that they would notice.

This issue was pointed out two days after the 5d3 hit the shelves, and people screamed bloody murder about it being soft,  and now suddenly everybody loves it.

I had the 5d2 and 1d4, and upgraded to the 5d3 and I absolutley loved everything except the image quality. And a bit higher iso's it's much cleaner than the 5d2, but use a bit of fill flash at iso 100 and the 5d2 files are sharper. It annoyed me to the point where I tried the 1dX more seriously to see if it was any better, and I sold the 5d3 as soon as I got hold of a 1dX. It's that big of an issue for me, and clearly others, including a couple of friends of mine who didn't know about this until they had tried the 5d3 for a couple a weeks and they came to me asking about it.

Lenses / Re: Migration from zooms to primes...your suggestions?
« on: April 04, 2013, 07:47:13 AM »
I've done what you're planning and it all depends. The initial reason I chose to switch to primes was because of light added, but completely fell in love with really shallow dof. The 35 L is an epic lens for me and my most used. The 24 I could never get rid of, VERY unique look with that wide angle and shallow dof .

Recently though the 1dx let's me shoot at MUCH higher iso's than my 400d with super clean images, so the need for faster apertures are way less now, along with I could use the flexibility of a zoom.

I just bought the 24-70 again and I can never sell it again, complete new life on the 1dx.

So don't choose either is my suggestion, keep your 24-70 and 70-200 and add a 35 L and architecture wise absolutely forget the 14mm, and if you want the best ( I know because I used to own it ) there's no way past the TS17, what a lens!

Both images are full size files.





I used the very cool MultiExposure method (as I learned here on CR). It's ONE raw file on both images, shadowpushed to +100 in LR, and +40-something with shadows in the tone curve. I was out to really push the shadows as a test, not to create a HDR-image, and this is why the whites are a bit over here and there. I specifically chose a VERY high contrast scene I didn't expect any camera to perform any good at all. And the light is nowhere near as crazy with the things I normally shoot, or care about if the subject looks good.

Those who say the 1d X is dissapointing need to figure out how to use it...

Although a tad awkard it's possible to use a battery-gripped body lefthanded , flip it so both shutters point up :P It's a bit tight between the thumb and forehead, but hey  ;D
