EOS Bodies / Canon 1D X firmware poblem?
« on: December 31, 2012, 10:22:32 PM »
I've run accross a problem with my 1D X when shooting in manual (M) mode.  If I have the camera set in Manual, the 2-second Self-timer enabled in Drive mode, and use Live View, the camera freezes up after taking a shot.  I've verified that it does this with both the 17mm TSE and 8-15mm fisheye zoom (just happened to be the two lenses that I was using...).  I have to turn the camera off and remove the battery to recover from it.  I went back and tried the 2-second self-timer and live view with the AV mode and it worked OK so it seems to be specific to Manual mode.  Can someone else with a 1D X confirm this behavior?  I'm thinking it may be a firmware bug; not a problem with my specific camera.

Everyone complains about the leather lens "Condom" that Canon uses with the large white primes as lens caps.  I bought this product for both my 200/2 and 300/2.8 L lenses:


I don't know if they are compatible with the newer version II lenses but, for the earlier version, they've worked great for me.

Does it bother anyone else that he thinks f2.0-f/2.8 is 3/4 of a stop and f/1.8 to f/2.8 is a full stop

Just because he can buy a lens doesn't make him a reviewer; it doesn't even make him a photographer  ::)

I've flown many times both domestic and international and always put it in my checked bag.  I turn the ball head to a right angle and it fits down one side of my large bag or diagonally in my smaller bag.  Never lost or damaged and I don't have wag it through the airports with my camera equipment...

I have one but I use it more for travel than sports.  The main advice I'd give it to be careful not to accidentally change the focus.  That lens has the zoom and focus rings reversed from the normal Canon placement.  When you handhold the camera the hand you cradle it with normally would rest on the zoom ring but for this one that is where the focus ring is.  It is annoying but I still like the lens.  It's IQ and IS are great!

Lenses / Re: 70-200 f/2.8L IS II focus issue
« on: November 18, 2012, 05:07:16 PM »
I had to send a 24-105L in for the same reason.  I have owned it for several years and it has worked well but, during the summer on a trip to Scotland, it didn't perform good at all.  When blown up, images were softer than they should have been, given the shutter speeds used.  I sent it to Canon and they corrected the various lens focus adjustments (including the "tilt" focus which I don't think MFA can address) and checked the IS unit.  When they returned it to me it was corrected to be within "Factory tolerances".  It's back to performing as good as ever.  Cost me nearly $200USD though…

If you manually clean the sensor for at least 30 seconds (just enable manual cleaning dont actually have to touch the sensor) it will detect and map out dead pixels. At least it does on my 60d. Im pretty sure this is done prior to getting a new camera, dead pixels are like dust- you will eventually have some no matter what

I've never heard of this but it seemed to work with a 5DM3 that I have.  It had what appeard to be a stuck red pixel that showed up from ISO 100-3200 (didn't try 50).  It seemed to disappeared at 6400 but I have the high ISO noise reduction set to auto and I think that removed it.  Anyway, I tried an Auto Cleaning cycle from the menu and then a manual cleaning cycle for 30 seconds.  After turning the camera off and back on, no more hot pixel.  I even looked at a RAW file in PS with all noise reduction turned off and it was gone.  It may not work in all cases, but I'm glad I tried it because I'd been thinking about sending it in to Canon.  All they would have done was map it out so I saved myself from being without the camera for a few days.  Thanks Ryan708...

I was interested in this lens until I took a close look at the MTF charts of it versus the 24-70/2.8L II.  Canon made it a more dificult comparison because the vertical scales are a little different between the 4 graphs.  At $1500USD, I'd expect the f4 version to be closer to the f2.8 in image quality and that doesn't appear to be the case.  Compared to the f2.8L II, image quality falls of near the corners for a full frame sensor.  It would probably be a great crop sensor lens though...

Lenses / Re: Sharpest Ultra-wide Lens for Full Frame
« on: September 30, 2012, 04:29:04 PM »
The term "ultra-wide" usually means around 20mm and wider.  The 17mm TSE L is about as sharp as you'll get in that range and of course B&H has it but it's not cheap:

A 500/4L IS II and two that Canon doesn't make; 100-300/4L IS and a 20/2.8 TSE.  I'd take a redesign of the 20/2.8 if Canon would upgrade it to an L but the TSE would be nice to have...

I enjoy threads where people discuss the need for an ultra-wide angle lens.  It is almost always when landscape photography is the subject.  Attached are three images taken last year at a lake near where I live to illustrate the difference of the three focal lengths that are most commonly discussed; 24, 17, and 14mm.  No they're not masterpieces but they do show how the perspective shifts between focal lengths change the importance of the various elements in the image.  At 24mm everything already appears twice as far away as it would with a 50mm normal lens.  As you step out to 17mm and then 14mm from the same camera position, the foreground becomes more and more dominate in the image while the background becomes less and less distinct.  That foreground domination is the reason to use an ultra-wide for some landscape shots; not to attempt to "get it all in" as many people do.  If the perspective looks right to you and you need a little more in the image, you need to step back a little, not switch to a wider lens.  If you do switch to a wider angle lens, you need to reassess the shot completely to make sure it is still a strong composition.
