Lenses / Re: Canon 35mm f/2 IS Review

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...

5D MK III Sample Images / Re: Lanscape: 5D mkIII 24-70mmL

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.

Software & Accessories / Re: GPS, does anyone really use this???
« on: September 18, 2012, 11:07:45 AM »
For travel writers/photographers, GPS is indispensable. No matter how good your memory, after tens of thousands of photos shot all over the world you cannot possibly recall where all of them were taken. Add-on devices, like the Canon GP-E1 for the D1X, 5D3 and 7D are expensive, bulky, add complexity, and serve a single purpose. Internal GPS, like in the 6D and Powershot S100, S110 have two downsides: they take too long to acquire satellites when you're frequently turning the camera on and off to conserve juice, and they consume more of your battery's power than the same camera body would without it. Far afield, when battery power is not easily replaced, this is a real concern.

I prefer to use a real GPS while shooting, like a Garmin CSx60, since it provides so much additional utility for navigating, setting waypoints, routing, tracking, etc, and is a far more sensitive and reliable receiver. I then use Early Innovations Photolinker software to match my daily GPS track to the day's photos. This tags each image with the appropriate coordinates in the EXIF data, shows you each image on a map, and allows for manual override when necessary (like when you're in a cave or slot canyon and loose the satellite signal). Lightroom 4 then displays each image's location on a world map once the image comes off of your memory card and into your computer.

I don't work for, am not sponsored by, or otherwise shill for any of these companies. This is just the best way that I've found to get my work done. There are a number of alternative geotagging software applications out there, but I haven't found any of them to come close to Jeff Early's Photolinker. It's fast, intuitive, comprehensive, and he regularly updates it. I hope this information proves useful.

The new GP-E2 replaces the need for a standard GPS unit for the 5DM3 unless you need it to navigate.  It acquires signal lock in less than 30 seconds most of the time.  I do a travel photography trip (usually to a country I'm not that familiar with) once or twice a year.  I was in Scotland last June for 2 weeks.  My memory is pretty good to but, 14 consecutive days of travel hitting multiple locations each day, the geo-tagging was a big help when I got home.  Plus if I ever want to return to the exact location I'll have the GPS coordinates to do it...

My only complaint about the GP-E2 is that it isn't powered by the camera and needs AA batteries.  I took lithium batteries with me and didn't need more than a 4-pack for the entire trip so it's not that big of a deal but it could have been made smaller if it didn't need the internal battery.


It is just another manufacturer's entry that makes the EOS M look stupid.  It has an EVF and built-in popup flash.  At least in other parts of the world, Canon is including the external flash with the camera (not here in the US).  The Fuji X-E1 kit also includes a 28-80 equivalent f2.8-4 zoom instead of the usual f3.5-5.6 uber slow zooms that most include...
