Yesterday I was filming a wedding with a new video light (1000watt lowel DP light), and I noticed that the brightest part of the light appeared black with bits of blue in my footage rather than white. (See sample jpeg)

Can anyone explain this? I was shooting with a 5D mkII.

Lenses / What to do with a broken 70-200 f/2.8 IS mkI?
« on: December 11, 2012, 01:18:06 PM »
Our 70-200 f/2.8 IS mkI hit the concrete this year, and after sending it to Canon for a repair quote, it'd cost more to repair it than to buy another used one ($1500).

Canon shipped the lens back to me, so now the question is: What should I do with it?
Do people actually pay ok money for shattered lenses?

I've heard of people turning lenses into cool household items like teabag holders. Any neat ideas?

If you're curious, here's what Canon says needs to be fixed:
RING, FOCUS ADJUSTMENT
FOCUSING ASS'Y, USM
LENS ASS'Y, 1ST GROUP
FRONT RING UNIT
LENS ASS'Y, 3RD GROUP
ZOOM UNIT
KEY, GUIDE
BARREL, INTERMEDIATE
RING, FOCUSING

I've got your EF 70-200 2.8L IS USM and there is an estimate that requires your approval.

Repair cost for this unit is $1,426.74
We are going to have to replace  a few parts on the unit they are;
RING, FOCUS ADJUSTMENT
FOCUSING ASS'Y, USM
LENS ASS'Y, 1ST GROUP
FRONT RING UNIT
LENS ASS'Y, 3RD GROUP
ZOOM UNIT
KEY, GUIDE
BARREL, INTERMEDIATE
RING, FOCUSING

LOL
Thanks, Canon! I bought the lens used for less than that.  :-\

Lenses / My unscientific 50mm macro shootout: Canon vs Zeiss
« on: November 18, 2012, 05:48:11 PM »
I recently had the opportunity to get my hands on a Zeiss 50mm f/2 makro planar, and I took a few shots to compare it to my Canon 50mm f/2.5 macro. The camera was placed on a table, and the shutter was triggered via a 2 second timer. I tried my best to line the shots up, but they aren't perfect.

These are 100% crops of the centre part of the image. The USB key image is the cover photo on a USB key box, hence the fine printing lines.

Lenses / The new Voigtlander 28mm f/2.8
« on: November 15, 2012, 10:23:02 PM »
A few weeks ago I ordered a manual focus Voigtlander Color Skopar SL II 28mm f/2.8 lens. The lens debuted in October 2012, and there has been very little press coverage on it now that it's out.

Now that it arrived, I've started to try it out. The lens vignettes pretty strongly at f/2.8, but that disappears by f/4. The centre image quality is excellent, even at f/2.8. The corners are soft until stopped down to about f/8, so it's probably not an ideal landscape photography lens. That being said, it's light weight makes it a great lens to pack when you're going for a long walk and don't feel like lugging a heavier lens. The tiny profile also prevents you from attracting too much attention. Even a 5D mkIII looks somewhat unassuming when equipped with this lens.

Another great feature is the accurate hyperfocal distance markings on the lens.

Here is a photo taken from a quick walk with the dog today. I wanted to take more, but he kept pulling the leash as I was trying to hold still! LOL

The vignetting in this shot was added in POST.  :)

The hood in the picture is a 3rd party ebay hood. It protects the lens without adding to the vignetting.

Lenses / New 50mm f/1.4 lenses are metal throughout?
« on: October 20, 2012, 03:27:25 PM »
I'm selling my 2011 Canon EF 50mm f/1.4 lens, and a person interested in the lens has asked me if it's all metal. Mine has a metal mount but plastic body.

The potential buyer claims the "new" 50mm f/1.4's are all metal. Is this true? I follow Canon rumors and other sites daily, and I've never heard of a new all-metal 1.4...

Lenses / 70-200mm f/2.8 took a bad fall... Any advice?
« on: August 26, 2012, 01:27:16 AM »
A business partner of mine dropped our 70-200 f/2.8 mkI, and the lens is in bad shape.
There is a half-moon shaped series of cracks on the second element from the front (though you can't seem to see it in photos). The AF and MF, however, don't work above 135mm. If you try turning the MF ring at 135 through 200mm, the ring does nothing or almost nothing, rendering the lens quite unusable.

Does anyone have experience with damaged lenses? Does this sound like it's a write-off now, or is there hope?
I'm going to take it into the Camera Store this week, but it'd be good to hear your experiences.

Thanks and take care of your gear!

Kevin

How do you pronunce the aperture of a lens? E.g. if you were telling a friend that you're shooting with an f/1.4 lens, would you say: "F one point four", "F one four", or something else?

Lenses / Lenses that inspire you?
« on: July 21, 2012, 02:28:33 AM »
I've been a firm believer that upgrading one's gear usually doesn't improve one's photography. However, I recently picked up the Canon 85 f/1.8, and I must say, this lens has definitely improved my work. Why? Interestingly, it's due to more than the image quality. Yes, it's a great, sharp lens, but it's really not head-and-shoulders above some of my other lenses.

So if the image quality of the lens isn't leading to noticeably better images - what's changed? Inspiration. For a number of reasons, when I shoot with the 85 I feel inspired.

First, the focal length. I spent most of last year shooting with a 50mm, so the focal length is a little longer, and it inspires me to shoot from different perspectives.

Second, the feel. The size and weight of the 85 on a 5D feels just right to me. It's light enough to not wear me out after a full day of shooting, but it's also solid enough that it doesn't look or feel like a toy.

Third, the image quality. There's no denying, this is a sharp, impressive lens. It may not produce quite the background blur of the 85 f/1.2, but the image quality is still pretty awesome. If I nail the exposure, focus, and composition, I can be quite sure that the lens will do the rest.

So, my question is: Is there a particular lens that inspires you and, as a result, makes you a better photographer? If so, what lens, and why?
