Nikon SB 910 with 70-200 mm f/2.8 II + TC 1.4
Apr 13, 2013

I am a  novice with using a flash. My goal is to learn how to use my SB 910 with the Nikkor 70-200 mm f/2.8 VRII and the 1.4 TC for wildlife ie birding.  I will be using my D800 with this set up.vThe SB 910 will zoom to 200 mm but not beyond according to the LCD display, but I will  be using the zoom at a 280 mm focal length with the TC. Does the flash account for the attached TC or do I have to make adjustments each time I use the flash in TTL/BL mode? Could you advise me how to make the proper setting adjustments when using the TC and possibly direct me to any resources that I might read? Thank you.

The SB-910 will zoom to 200mm and that's it.  Some outdoor photographers use a Flash Extender  to provide up to 2 to 3 f/stops more by concentrating the light in a tighter pattern.  The model you want is here .  Your TTL will expose correctly using it.

The flash will not account for the TC and the extra focal length, but your TTL metering will meter correctly and try to balance the ambient and flash output based on the scene you are shooting.

Now, the issue will be if the SB-910 has enough power to provide the balance flash at the distance you desire and ambient light conditions.  One way to try to achieve this is through flash compensation (up it), another is going to higher ISO settings and upping your shutter speed to maintain the ambient you desire.  But you really need to keep your shutter speed at or below your x-sync otherwise you will lose a ton of power in HS FP mode....no free lunch here.

You really just have to go and practice different settings and review the results.

There are books on Amazon and Barnes & Noble that deal with outdoor photography, bird photography, and flash photography, just have to search.

There really is no substitute to just setting up a tripod, mount your lens and camera with flash and take a bunch of test shots of an object at about the same distance and using the focal length you typically will be shooting.  Try different settings until you gain confidence with the results.  Not sure what mode you shoot in either? M, A, S, or P?  I have read that the best way to get TTL BL to work correctly is: 1) outside and 2) your camera in P mode.  I have not verified this statement though.  I tend to never use TTL BL, but prefer to use straight TTL and balance it myself.

Regards,

Here's a useful link for information on the Nikon CLS Flash system .  It is a blog written by Russell MacDonald, called Nikon CLS Practical Guide.  Some very good information there.

I have the Nikon D7000 with a Sigma 70-200 mm f/2.8 and Sigma tele TC 1.4. So here's what it looks like when you shoot in A mode at 200 mm:

Not my greatest work, but you get the idea

Generally speaking, the camera and flash together can produce a photo that is exposed properly if you are within the correct distance, regardless of the zoom factor.

The SB-910 may also choose a higher ISO than you might, so remember to use the Commander setting.

I need to clarify that in the above post, the camera was in Aperture Priority, or A mode. The flash was actually in TTL BL mode.

Hey, I am brand new to the SB-910 as well, though I have used flashes for decades. I am now learning the modes and EV settings with my new SB-910, with the help of Joe McNally's books and videos, and The Nikonians' book "The Nikon Creative Lighting System, 2nd Edition" by Mike Hagen.

The 200mm isn't how far the flash can reach. 200mm means that the flash is optimized for maximum power in that smaller field of view, over lets say 70mm. 70mm needs a wider flash spread thus weakening its theoretical throw. Zooming the flash means the beam is tighter but can be 'thrown' further.

The lower the f number the more powerful your flash will seem to be on the exposure.

Put your flash on your camera, zoom it to 200mm and use an aperture of f2.8. This will give you the maximum throw, relative to Iso. If your then still underpowered, increase your Iso to suit..
