3-0 out of 5 stars 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.
4-0 out of 5 stars 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.

4-0 out of 5 stars 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 is a great way to get closer without paying a significant amount for a supertelephoto lens. ... Read more

3-0 out of 5 stars Twice the reach at what price?
This extender is limited to which lenses it will work with, most of them L lenses. The II model features a new seven-element weather-resistant design, and improved anti-reflection internal construction. Auto-focus is possible with any EOS body if an f/2.8 or faster maximum aperture lens is used.Image Stabilization lenses maintain the IS feature when used with current EOS cameras.Using this extender with any lens will eliminate one or two f stops and decrease sharpness to some degree.
3-0 out of 5 stars Only acceptable on big glass
This is a good accessory with a 300mm f/2.8 or above. The problem comes when you try to use it with the Canon L zoom lens like the 70-200L or the 100-400L. You lose so much sharpness that it not acceptable for a pro or advanced am, which would be the people buying this accessory. If you have big glass then you should get this, otherwise stay with the Canon EF 1.4X II Extender and get publishable photos.

3-0 out of 5 stars Double Your Reach for a Cost
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/2.8 and faster on most camera bodies. You do also give up image quality by putting this between your lens and camera body.When using longer telephoto lenses with this, you will want to use a tripod, cable release, and mirror lockup in all but the brightest of conditions.If you need this much extra reach you may be better off getting a 1.6X camera body or saving up for a longer lens. ...

3-0 out of 5 stars Bargain alternative to Canon's 1.4x Teleconverter?
The Sigma APO teleconverter is a little more than half the price of the Canon teleconverter, and it boasts an APO element to reduce chromatic aberration.I've found this teleconverter to be reasonably sharp, but there is noticeable vignetting when I use it with my Canon 300mm f4.Sigma claims that the teleconverter is designed to be matched with their high-end tlelphoto lenses, and perhaps this is the case.However, I wasn't very satisfied with the performance of this teleconverter. ...

5-0 out of 5 stars Fabulous image quality but less reach
I have used both the TC-17E II and this one, the TC-14E II.This one multiplies the reach of a zoom lens by only 1.4.There are two other Nikon teleconverters in this series, the TC-17E II (1.7 multiplier) and the TC-20E II (2.0 times multiplier).The "E II" series of teleconverters is only suitable for certain Nikon lenses--check the Nikon website for compatability.I purchased this teleconverter for use with the 70-200VR F/2.8 lens, with which it is quite compatible.

5-0 out of 5 stars Excellent Teleconverter
Works wonderfully with my Sigma 70-200 f/2.8 HSM. Fast, very sharp. Seems to be very well made. A great addition to any fast Sigma lenses.

5-0 out of 5 stars Excellent converter.
I use this converter on my Sigma 70-200 f/2.8 HSM Nikon mount.I used it first last fall at the Petit Le Mans at Road Atlanta and was very impressed with the results. Aperture is reduced to f/4, which is still a bright finder, and autofocus operation is not negatively effected. All electronic functions such as HSM and D coupling still work. Very sharp from my experience. ... Read more

1-0 out of 5 stars INCOMPATIBLE, INCOMPATIBLE, INCOMPATIBLE!Ugh!
See the excellent review below which lists the pitiful handful of Sigma lenses that this teleconverter is compatible with.I wish I'd read it before I ordered it (I had to return it after opening it, the list is only INSIDE the booklet*).I have several wonderful Sigma lenses, but none are on that list, and the ones on that list would duplicate what I have, so I have no intention of bying one of the few lenses this teleconverter could work with.*Also inside the booklet is a warning that trying to use the lens with any lens not on the list may damage both the converter and the lens.Well, yeah, a quick glance shows that they used the standard connecting bayonet at only one end (the camera end) and used some strange lens-specific screw mount at the other end.And the possible reason:My Nikon camera body has plenty of space behind the bayonet mount in case the lens needs to extand back a little, but this teleconverter extends FORWARD beyond its front so only a lens with plenty of space "in front of" the bayonet mount (ie, at the lens' camera end) would be able to mate with this.So it looks like they have to specially design lenses just to be compatible with this odd teleconverter, and that would explain why the list is so short.

1-0 out of 5 stars Buyer Beware!
This converter not only work only on Sigma Lenses - BUT CERTAIN SIGMA LENSES!5-0 out of 5 stars Great teleconverter.
This 2X teleconverter is a great addition to any fast Sigma lens. I use mine with my Sigma 70-200 f/2.8 HSM. It is sharp, well made, and a relative bargain. I recently used it to shoot at Road Atlanta and was very impressed with the results.Read more

3-0 out of 5 stars Not for action photography
I'm going to state up front that I haven't used this 3x teleconverter.I have no idea whether it has acceptable optical quality or not.The idea of a 3x teleconverter sounds very promising and nifty, but there is a large tradeoff involved.If you use this teleconverter, the effective aperature of the lens you are using will go up be three stops.This makes for eight times less light entering the camera lens, resulting in shutter speeds that are eight times slower than the lens would achieve without this teleconverter.
