New Rental: Canon 2X Teleconverter version III !
Posted on September 17, 2014 by Sean MacDonald
The following shots were with the 70D, 70-200 f2.8L II, 2X III.
Shot at 70mm (no tele)
Shot at 200 (no tele)
Shot at 200 with 2X Tele
(also note, there is steam causeing blurry parts of the image, not from loss of quality)But there are some drawbacks to teleconverters. The first being the loss if light. With this 2X tele, the light loss is 2 stops. Meaning if you have a f2.8 lens, it will now be a f5.6 lens. If you have a f4 lens, it will become a f8 lens. Most non 1D series cameras will not focus a f8 lens, so for most of us, we need to be shooting a f2.8 lens in order to have auto focus (only exception is the 5DIII). No worries though, you can always rent a f2.8 lens if you do not have one.
The second draw back (which was more prominent in the past) is a drop in image quality. Because you are adding more glass and elements, some quality loss is inevitable. The questions is how much. Previous to yesterday, the last lens I shot with a teleconverter was a version I 70-200 f2.8. At the time, the current version of 2X teleconverters were the version II's. So with a version I lens and a version II tele, I saw pretty poor image quality in both sharpness and chromonic aberration. At that time, I decided I would rather have the quality than the length.
But yesterday and today, I have been shooting the 70-200 f2.8 version II and the 2X tele version III, and I have to say the quality is much much better. The images are sharp, and I do not see any chromonic aberration. I now can confidently recommend this setup, as before with previous versions I would have been very hesitant. I can also say that this setup is sharper than Canon's 100-400 f4-5.6L lens. I like Canon's 100-400 for portability and ease of use, but anything from the 300-400 range really deteriorates in image quality. Plus, if you went with the 70-200 and 2X setup, you have more flexibility by remove the 2X and still shoot at f2.8. You cannot do this with the 100-400. I have not had the opportunity to try the new tele version III with the old version I 70-200 or the new 70-200 II with the older version II tele, so I do not know which is the weaker link. My speculation however is that it would be a little of both, and when stacked together it becomes a problem. Either way, this setup together seem pretty sharp.
The picture below is on the 5DIII with the 70-200 f2.8II and the 2X tele III zoomed to 400mm at f5.6, 1/160 with IS hand held.
So who should rent the 2X tele? Or who should rent the 70-200 II and the 2X III?
I would say if you are thinking about purchasing either piece, you should rent them first. Or, if you already rock out a 70-200 f2.8II all the time for lets say weddings, and you want to take a day and shoot eagles by the river then rent the 2X tele.
Or if you are a hobbyist, and you cannot even think about buying either of these (about $3K together new) but you want to take a day and get some better eagle pictures than you have been able to get with you current gear, then maybe make this a late Christmas gift to yourself :)
If you are thinking about puting this 2X tele on you 75-300 lens, let me stop you right there. There teleconverters will only work with specific Canon lenses. They are by no means universal. They will not work with your 75-300, 70-300, 55-250, or other EF-S lenses and some EF lenses. Basically the list of lenses that are not compatible is longer than the list of lenses that are.
This is the list of compatible lenses:
Canon EF 70-200mm f/4.0 L USM Lens
Canon EF 70-200mm f/4.0 L IS USM Lens
Canon EF 70-200mm f/2.8 L USM Lens
Canon EF 70-200mm f/2.8 L IS II USM Lens
Canon EF 100-400mm f/4.5-5.6 L IS USM Lens
Canon EF 135mm f/2.0 L USM Lens
Canon EF 180mm f/3.5 L USM Macro Lens
Canon EF 200mm f/2.8 L II USM Lens
Canon EF 200mm f/2.0 L IS USM Lens
Canon EF 300mm f/4.0 L IS USM Lens
Canon EF 300mm f/2.8 L IS USM Lens
Canon EF 400mm f/5.6 L USM Lens
Canon EF 400mm f/4.0 DO IS USM Lens
Canon EF 400mm f/2.8 L IS USM Lens
Canon EF 500mm f/4.0 L IS USM Lens
Canon EF 600mm f/4.0 L IS USM Lens
Canon EF 800mm f/5.6 L IS USM Lens
Canon TS-E 17mm f/4 L Tilt-Shift Lens
Canon TS-E 24mm f/3.5 L II Tilt-Shift Lens
Canon TS-E 45mm f/2.8 Tilt-Shift Lens
Canon TS-E 90mm f/2.8 Tilt-Shift Lens
My original goal for adding this 2X tele was to add a good option for those wanting to rent a lens setup for shooting eagles, getting to about 400mm and still retain excellent image quality. I fell that this setup will do that well. Maybe someday we will get a 600mm or 800mm lens :) until then, this will have to do the trick!
Lastly, the rental price for the 2X Tele III is $20 a day, and the 70-200 f2.8L IS II is $60. If you want to rent both together, we will give you a deal for $70!
