Lenses / Re: Your technique for switching lenses in the field?
« on: October 26, 2012, 06:20:36 PM »
1. Remove current lens.
2. Add new lens.
3. (maybe) remember that I should have turned the camera off,... turn off and on just run sensor cleaner.

Canon EF Prime Lenses / Re: Canon 400 f/2.8 IS
« on: October 23, 2012, 10:34:36 PM »
I had a chance to shoot pro surfing.  Was pretty fun.  i had the biggest lens on the beach, including the press, untill a guy showed up with a 600m f4.  But I had a 1.4X and 2X extender, so i like to think i still won.

Lenses / Re: New 50mm f/1.4 lenses are metal throughout?
« on: October 22, 2012, 08:39:18 PM »
Thanks for the info!  I'm glad to know I wasn't crazy for doubting the existence of a new, all-metal 50. (Though it'd be great if Canon would make one!)


If Canon made an all metal one, I'd get it in a heartbeat!

If they can make one without glass, I will buy one too.  :)

As this lens was introduced in June 1993, it seems a bit much to call it new.

If your income is tied to your photography, you need to have 2 bodies.  You like the 5D II, keep it. 

Your lens choices sound great.

EOS Bodies / Re: do crop sensors really add reach?
« on: October 19, 2012, 11:38:31 PM »
Is the crop 7D going to have more reach? Yes of course.  But of course you can just crop the FF image for more reach also.

is the 7D going to yield more pixels vs. the cropped 5D/ yes of Course 

Is it going to yield more detail? Depends if the lens is sharp enough. And the 100-400 is not known for sharpness at 400. So maybe not.

On my 400mm f2.8 IS I, my 7D has way more reach and detail than my 5D II (now III)


My 100-400 is excellent at 400, wide open.  And coupled with my 5D3, the images are much nicer than what came out of my 50D.  I attribute a good part of that to the AF of the 5D3.

So to the OP, you have an excellent lens lineup.  I think good AF is a major factor for wildlife.  I'd go with either a 7D or 5D3 for the AF... or 1D4, 1DX if you can afford such.  If you go full frame, replace the 10-22 with a 17-40 unless you need the extra stop of the 16-35.

I'm sure your 100-400 is great. I used one before and it's a really nice lens.  It's an excellent lens for what it costs.  But if you are not seeing more detail from significantly higher pixel density, either one camera is focusing incorrectly, or you reached the lens's ability to resolve detail with the lower density camera.  I don't have a 50D and can't speak to it's focusing ability, but it does not not have the ability to tweek focus, your 5DIII does. Correcton, the 50D does have focus adjust.  Did you use it?

The 100-400 does not compare well with prime lenses in the same focal lengths

The Sigma Lens is their show piece.  More of a "yes we can!" than a "lens you need!"

I've never seen a photos from it that were not part of a review or test.  When you try to find photos from it, all you get is photos of it. http://www.flickr.com/groups/200-500/

Software & Accessories / Re: Arca-Swiss requires plate
« on: October 14, 2012, 12:34:09 AM »
The fantastic thing about the arca-swiss system is lots of manufactures make it, and they are all cross compatible. 

Many (but not all) have a safety system of pins that will keep the plate from falling off the ball head if you loosen it but don't completely undo it.  In this loose position, you can slide the plate back and forth to get positition and balance.  (Or you can just be happy your camera did not fall on the ground because you did not make it as tight as it needed to be.) Not all have the safety system, and I avoid the ones that do not.

One of my favorite Arca-swiss add ons is the Wimberly Sidekick.  It converts your ballhead into a long lens gimbal system without removing the ball head.

Reviews / Re: Review - Canon EF 8-15 f/4L Fisheye
« on: October 13, 2012, 11:50:52 PM »
The first image in the article is almost certainly shot at 10mm and labeled as 8mm.

I love this lens, and have always loved fisheye.  I find the circular fisheye much less useful, but still cool.  Full faram fisheye on my 5DIII AND my 7D? AND my 1D Mark IV?  Awsome.

A couple tips: 1. It's still full frame on a FF, at about 14mm, and even wider.
2. When shooting circular, I zoom to about 8.5-9mm so I don't have black borders on top and bottom, then I crop to circle in photoshop.  This has more "perfect" circular edges and gets you more verticle (and horizontal) pixels that are not just black.
3. Crop circular images to square, and more web services (flickr etc) will display them significantly larger..

Lenses / Re: Canon 800mm F5.6L IS USM experiment
« on: October 13, 2012, 04:41:08 PM »
I need a zoom lens that covers that range. :)  (Plus I'd like circular fisheye on the wide end.)
Very cool, thanks.

I am a big fan of the 24-105, and highly recommend it, but your decision there is kind of 50/50.  Body or kit?, I'd go with the best deal you can find, counting on the 24-105 as worth $800 more than body only.

If you end up with both, use both and see which you like.

If you get the body, shoot with you current lens for a while before making any deception.  I think in 6-12 months the 24-70 II may be way more reasonable, and then you'll have to consider that as well!

Canon General / Re: Weathersealed Camera Gear used in wet conditions
« on: October 13, 2012, 01:23:16 AM »
Do I use anything else?  Hell Yes!  Weather resistant does not mean water proof, and my gear is not cheap.

1. First line of defense is I don't go out in the rain with my camera in general.  Sure if there is something worth shooting, like for example I'm getting paid, or the big foot convention is in town.  But I don't go outside in the rain for no reason.  Why?  Seriously what are you going to shoot? I sell stock photography, and there is little call for the rainy drab photo of ____.  What a great day for post processing!

2. I use LowePro all weather (AW) Bags.  My main bag actually has 2 rain covers, one for the top for light rain, and one that covers the whole bag.  Both fold up into pockets.  I also keep a trash bag inside to bag up a camera on tripod, convert to a poncho, or ultra-secure my bag if in a small boat or something. ( a .$50 trash bag is cheap insurance)

3. Pelican cases.  When i shoot pro surfing, or some similar event that gets me in the sand, I love my pelican cases.  They can be seats on the beach, and when you get home, you wash the outside with a hose.

Lenses / Re: Need opinions on telephoto choice

I have a 400mm 2.8 IS I, and both vIII extenders. I was not aware it was was a bad combo  :D

I agree with the above posts.  My combo is because I am 80/20 sports/wildlife.

Sounds like focus breathing.  Also when you are close, camera placement can have an effect.

It is interesting though because when you have one 70mm lens, its 70mm, but when you have 2, suddenly there is an issue.
