Only the centre point is available, or centre-surround. Great post! What combo would you suggest for birding : 7D Mark II combined with canon lens mm and 1. Can you elaborate on this? Is this due typically increased relative pixel density in crop sensors exceeding lens ability to resolve, or something else? Your email address will not be published or shared.

Gosh this was a long time ago. Out of curiosity, why do you want to know? Dan, Getting ready for a Yellowstone trip in May. I guess I just need to hear it from someone that has your experience. Thank you, Dave Reply. Do you use the mm in combination with 2x extender? What do you think about this combination? Go to Solution. I must be doing something wrong. I am using a 2x ii extender.
Autofocus will not work. When I try to focus on an object, the f stop setting is flashing on the display. Any suggestions? What shooting mode are you using. Try using M mode.
How many focus points are you using? Use just the center one in the viewfinder, and then try Live View, although I do not think that will really help.
The minimum aperture is probably too high. The extender instruction manual can tell you which combinations of lenses it is compatible with. You camera instruction manual should tell you which focus points would be available, which in this case I would expect none to be available in the viewfinder. View solution in original post. It is technically compatible, but not very practical.
A 2x extender doubles the focal length AND the focal ratio. The length and weight of this combination means no hand held, tripod only. I use a stylus, as for an iPad etc, to chose the focus point on the LCD screen in live view, and the new auto focus system instantly focuses on that spot. I am getting results at mm mm with 1. So, to those blogs I read that say the Canon teleconverter stops auto focus, look again with a 70D in live view!!
When the high end cameras recieve this new dual pixel sensor technology, the teleconverters will be very useful. In particular, if you tripod mount the lens both with and without the teleconverter, and compare the quality of the photos blown up to full pixel resolution, how good does it look. Is it still worth the investment to get the extender considering that you will need to bump up the ISO to get the same shutter speed adding noise or reduce the shutter speed to keep the same ISO adding the potential for image movement.
Adding a 2X teleconverter is tempting but if it reduces the quality to what I'd get hand holding the lens then its a poor investment for me. I ended up buying both the 2x extender and new lens and it turned out to be a good decision. In short, the image stabilization on the mark II lens is indeed amazing even with the 2x extender and well worth the investment.
I had read numerous online posts from "experts" that an extender will make the images look soft and that you will lose contrast. I decided to put this to the test. I want to be able to take wildlife headshots that show whisker detail from far enough away that there's no danger of getting my face ripped off or getting gored.
So I set up a resolution test chart 75 yards away in a somewhat open forest that had dappled light, probably the worst conditions that I could expect to be successful in. I then took multiple photos and varied the following: Old and new lens, no extender, 1. Shutter speeds were slow at reasonable ISO settings due to the light and gave a good test of real world conditions.
