USM lenses have a slip clutch that lets the focus ring override the AF motor. This makes the focus scales totally worthless unless you first set the focus to infinity or minimum each time. Don

If you are trying to be inconspicious, a white telephoto is not it. The 70-200mm f/4L is very good. Even my 24-105mm f/4 turns heads with all that glass out in front.

If you can wait until a 5D MK III is available in store, you probably don

If you were pointing it downward while using or moving the multi-controller, you were opening it up for rain to get in. Its really difficult to seal that multicontroller, but as long as your camera...

Give Canon a call, they will probably send you a replacement. they do not want those "L" lenses going around without a proper red ring.

With my 40d, I had the 17-55mm as well as the 24-105mm L. both were excellent and the 24-105 would have been perfect it it went to 17mm. So, I switched back and forth, but tended to favor the 24-105...

A lot of the "POP" in photos comes from post production. Many use RAW and a editor like lightroom to adjust the image to look like it should. It can make a huge difference to add a little sharpness...

Some users have reported 580 EX II flashes failing while using Pocket Wizards. There is no proof that they caused the issue, but, the range issue and the unknown reason for flash failures are...

I've tried many telephoto lenses, 400mm 5/5.6L, 600mm f/4L, 70-300mm IS, Tamron 200-500mm, Sigma 400mm, etc. The 600mm L was the best, of course, but I could not take it with me for a quick shot, it...

You can buy inexpensive remote flash units that are triggered by the on camera flash. This happens so fast that it makes no difference to the lighting. You will need to set everything manually, but a...

I bought a TS-E 90 for use with my 5D MK II for product photography, its a very nice lens, and does close focusing as well as accepting a TC. If you need a little more magnification, use a TC....

Have you checked light levels? f/4 seems like it will bea challenge if light is low. I find that even f/2.8 is a bit limiting in dimly lit arenas where a fast shutter speed is required. IS is of no...

I have found that using the modern autofocus lenses for manual focus, (with the exception of the big whites), is pretty difficult. Not only are my eyes getting old, but the short throw of the focus...

I bought a used 600mm L, nice lens, but not long enough for wildlife unless you were pretty close. I took it to a local gravel pit wherelots of eagles hang out. I thought i was pretty close, but put...

Well, I have a inside contact at Canon, and he gave me one to play with for a week.


If you believe that, I have a bridge that is available at a durned good price.

I would never consider trading my 100-400 for the new 70-300mmL. However, each of us has their own priorities. It is light weight and takes up less space. However, if you ever step up to FF or a 1D...

As noted, they are MK II

I have used the 70-200mm f/4 with 1.4X, 2X, and both stacked with good results. However, its not at all user friendly to add and take off the extenders in the field.

I sold my 3 year old 17-55mm on ebay for $900 on ebay. If I were to take it to a camera store, I

Alex, with your setup, the camera could indeed lock on to different lines at different times. That tape with all the closely spaced lines is just inviting this.


Here is a proper test chart...
