The RAW image was processed with a low sharpness setting of "2" "3" is Canon's default setting. You can see the very thin plane of sharp focus running through this cropped image. Maximum magnification can be increased via the use of Extension Tubes. Telephoto lenses typically show higher MM values with a Canon D Close Up Lens , but the D is not available in 67mm filter threads at review time.
This is the only Canon L zoom lens with a widest focal length of 70mm or longer that is not compatible with Canon extenders as of review time. I've tried mounting Canon extenders to the L - and they do not fit. The rear L lens element physically hits the front element of the extender.
Intrigued, I did more experimenting. What I learned is that the L's rear element retracts into the lens far enough that, at about mm, there is enough clearance for Canon extenders to mount.
The available with Zooming out wider than the mm-or-so zoom ring mark results in a physical bump inside the lens. I'm guessing that it is the rubber around the edge of the extender element contacts the rear L lens element or its barrel. I do not recommend mounting this combination due to potential damage to the lens.
I of course felt the need to try out these unsupported combinations. My solution to the damage risk issue was to Gaffer Tape the lens zoom ring to lock it at the mm mark while using extenders. Mounting a 1. While it tries, the tested 1Ds III body cannot lock focus with this combination. The interesting part of this story starts with the fact that the Canon Extenders do not report their presence when mounted behind the L.
And what is much more interesting is that the L and 1. Autofocus speed with the 1. Since I'm sure you are wondering what the image quality from these combinations looks like, here is a look at the Canon EF L with EF 1. Image softening from the 1. CA becomes pronounced with increasing amounts visible toward the outer image circle. Wide open, the results with the 2x installed are remarkably close to the performance of the 1. The 1. Again, the with-2x combination has problems locking autofocus.
While the image quality of the L with extenders is not impressive, it can certainly be usable in a pinch especially in the center of the frame with the 1.
In addition to accurate focusing, a steady camera and lens is essential for a quality image. While tripods rule, image stabilization can make a huge difference when handholding.
Under good conditions no wind and stable footing , I am finding it easy to get the rated 4 stops of help from the IS system on this lens. And I'm even seeing 5 stops of assistance at a good percentage-sharp rate. I even have some sharp shots with exposures as long as. Out of 13 test shots taken at this about minusstop setting, 5 of them look like this.
I'm impressed. Shooting in the wind? You will not likely be happy with your results at these test exposure durations. Wind is very destructive to image sharpness - Especially with longer focal lengths handheld. I often find myself using this lens in very strong winds - and often make this lens more aerodynamic by removing the lens hood under these conditions. Most image stabilization systems are audible. The L's IS makes a quiet churning sound that increases when the lens is moved rapidly.
Put your ear against the lens and you will hear the sound clearly. Add a little ambient noise and you'll barely hear it from behind the viewfinder. I frequently talk about the advantages IS provides to image sharpness, but I probably do not mention enough the aid IS provides to composition. The longer the focal length you are using the narrower the angle of view , the harder it becomes to perfectly frame your handheld shot. I was then encouraged by how a preproduction L IS performed in all regards including optically.
While it tries, the tested 1Ds III body cannot lock focus with this combination. The interesting part of this story starts with the fact that the Canon Extenders do not report their presence when mounted behind the L.
And what is much more interesting is that the L and 1. Autofocus speed with the 1.
