Oh, one additional thought. As an added bonus, the 2x converter also lets you do some decent close-up shots as well since mm at 1. R Hall R Hall 1, 9 9 silver badges 12 12 bronze badges. And of course it increases cost and weight, though not as much by far as purchasing a or whatever. Brent Brent 21 1 1 bronze badge. Sign up or log in Sign up using Google. Sign up using Facebook.

If so can I see some examples of your pictures? I've read about lots of issue with sharpness and focusing and I want to see some examples. I am wondering the same!! I want a but I want mm too so im in this boat as well.. I just got a and have a 1. I was impressed with the results. Luminous Landscape did a review comparing the with a 2X to a I would like to see the examples as well. I should be getting the lens soon so If no one posts by then maybe I'll rent a teleconverter to try it out.
Canon EOS 30 D A lot of people find that stacking two 1. I have tried this on my f4 and 40D and I reckon IQ is better. A bonus with the f4 is that the Camera only sees one of the Tc's so AF still works on a non 1 series body. Auto focus works with either TC as well as with both stacked--but I have to stack the 1. My images are not too good with the stack or with the 2x--but I didn't expect it to be, especially hand holding, and that's why I got it.
I use the 2x with the lens for sort of a spotting scope and to document different deer on my hunting properties. I really don't care about the quality, and I am sure I would get much better results with a tripod. I don't even bother with the 2x at a motocross track, but in good light, I have gotten some realy decent results hand holding the lens with the 1.
On a tripod the 2x or the stack works pretty well, especially with mirror lockup and 2 second timer. But I really don't have time for that, deer don't stay still long enough. I need to try some moon shots however. I'd rather have a for sports, but I am waiting for an upgrade to this lens. The new Sigma looks tempting!
I need to read some reviews. Rudy M. One of the first concerns I have when adding an extender is the impact to image sharpness. Overall, these lenses are both so sharp that image sharpness is not a significant differentiator over the native focal length range overlap.
The of course needs help from an extender to cover the mm comparable range. Adding a 1. The performs quite well with the 2x, but the difference in across-the-frame sharpness is noticeable with the showing a moderately strong advantage in the mm comparison.
