A little extra reach at a price

This extender is limited to which lenses it will work with, most of them L lenses. Using this extender with any lens will eliminate one f stop and decrease sharpness.Auto-focus is possible on any EOS camera when used with an f/4 or faster maximum aperture lens. The version II extender adds enhanced weather-resistant construction, and improved anti-reflective surfaces in the barrel.I rented this extender to use with the Canon 100-400mm f/4.5-5.6L IS USM lens. This lens while sharp and high in quality...

Just a Little Extra Reach

Make sure to check the compatibility charts to verify that your lenses will work with this before buying it since only a handful of L series lenses are compatible.If you do already have one or more of these lenses though this is a nice addition.The AF only works with lenses f/4 and faster on most camera bodies.You do also give up a little image quality by putting this between your lens and camera body, but the extra reach is really nice....

Nice accessory to get closer

I have used the 1.4x II extender for over a year. It gives me amazing detail with my 70-200L f/4 lens on a 20D. I use it mostly for wildlife and butterflies. Contrast is good with colors that pop. When shooting on a sunny day the shutter speeds are still quick with the f/5.6 and the background is blurred beautifully. In shade areas and low light a tripod is a must! There hasn't been any sacrifice in subject detail. I can see individual hairs on butterfly bodies even when shooting wide open. This...

It's Just Not Enough

I purchased this at a photographic store because a professional said you shouldn't go higher than 1.4x.Just keep in mind--1.4x is only "40% better".It worked really well, but didn't increase the zoomage enough.I decided to go with a 2x (that's twice the zoomage) teleconverter by kenko instead.I gave this one to my brother-in-law for Christmas.You have to think about what you want--I want to get in really close to the birds.I have a 70-300mm zoom lens and 1.4x takes it to 98-420mm.It is an improvement...

A great way to extend the reach of compatible lenses

The 1.4X II teleconverter is a modest update to Canon's earlier 1.4X TC.The mark II allows this extender to be stacked with another of Canon's extenders (either another 1.4X II or the 2X II) without having to separate the two with an extension tube (although the loss of sharpness from stacking extenders may not be acceptable to you).Otherwise, the quality of the newer 1.4X II is supposed to be very similar to the older model, which I've never owned.The 1.4X II is a great way to extend the reach...
