The slide out, plastic diffusion screen that is built in to the head will set the zoom automatically at 14mm. If it is not properly seated when you retract it, sliding back into the hidden position, then the electronics are fooled into thinking it is out and covering the lens. Play with it until it properly is retracted and fully seated within the flash head.

IS will not matter at this focal distance. Only start worrying about IS (or VR as Nikon refers to the technology) past about 70mm

Measurement in feet. You will not go wrong if you purchase this lens. I love it! The clarity is excellent. It takes a while to get the focus exact, but once you work with the lens you will not know how you did not buy this sooner.

No it is not a zoom lens. It's a fixed length prime lens. The 42.5mm micro four thirds lens is the equivalent of an 85mm lens in the 35mm system.

The Sigma 10-20-mm lens will do that: at 14 mm focal length the field of view at 3 feet from the lens is 5.03 feet. However, the faces will be distorted. You can get the same field of view with a 28 mm lens at 7.0 feet with somewhat less distortion.

I can close focus at 7 feet with a 1/4 twist of the black ring near the objective. The little knob is where you can mount it to a tripod.The slider from "15x to 55" is near the eyepiece and just slides 1/5 turn easily and smoothly. It is really 10x to 25x.

I have lens from a 24-70 mm, a 50 mm f1.4 and several others that the flash fits on, only one is doesn't fit is the 150-600 mm tamron.

I believe the 70d is a crop-sensor, so it would give you the full-frame equivalent of 56mm.

This lens has a comparable focal length of 16 - 28.8mm in a 35mm equivalent. If you have any further questions or concerns, please don't hesitate to contact our sales department at 800-991-3350 EST. We thank you for your time and consideration!

The zoom on the standard lease is 10-30mm. I can't give an answer on the was it time between shots.

I have no idea. The 70-300 gives me access to short range subjects and my grandson has used it for senior pictures. The L lens is the best I believe.

Close in focus is a problem with that lens. I have often found that a problem. The minimum focus distance depends on the zoom ratio selected. At the 28mm setting, the camera will focus down in the macro range (marked in orange on the focus distance ring) and that gets you to about 4 feet. The lowest focus distance marked in white is 2 meters, and that applies as the minimum focus distance with the 200 mm zoom setting. In between it varies proportionately to the zoom setting as to what your minimum focus distance is. In short, if you do a lot of work close in, this lens is not a good choice. I have no experience with extension tubes.

Yes. All EF lens will fit. This is not made for a crop sensor. So this lens will not be a 28 to 70 it will be 1.6 larger than that. Not great in math but it would top out a little over 100. So you won't get the wide angle of the 28, and you can zoom in closer than you could with a 70. The lenses for canon for crop sensor Canon D notes as EF - SBut they will only work perfectly on crop sensors and don't work on full frame sensors. I would never buy an EF - S because someday in the future I may upgrade my body to a full sensor and want to take my expensive lenses with me.

What it does is, it will extend your lens' zoom by 1.4X. Meaning if you mount the Kenko 1.4X pro into you T3i, your 70-300 mm becomes 98-420mm (70x1.4=98, 300x1.4=420mm). However, you maximum aperture of f/4 will drop to less tha f/4, possibly f/5.6. Please take note that Canon T3i has a APS-C sensor, so your actual zoom would be longer than 98mm-420mm.

Outperforms the 70-300 VR in that is can zoom back to 28mm. That is why it is twice the price. It does not produce better images between 70 and 300mm. I would chose the 70-300 for the longest shots, and the 28-300 for shorter. Both lenses are as professional as the person using them, do not be impressed by reviewers waving wads of bills at you, because like a Violin, a Camera/lens is only as good as the user!

72 mm but be careful, because I have the first version of this lens, the last is 62 mm.
