i'm using it with d1x...very sharp images...some say there kinda soft...but good enough for me...only regret is its kinda slow autofocus at time...and it hunts around...not the best lense for low light conditions...i think if they put afs in it...its a perfect combo...but all overall...it still recommend it....not sure about the af in d100...heard its a little slower?...i would like to see some comments too..and i have not used a teleconverter...not sure its that good of a idea though...maybe not..what are other opinions?
I also use the 80-400 VR on my D1x. It delivers crisp, contrasty photos handheld all the way to 400mm. It is a little slow on the AF, but to me it still seems faster than what I was used to with the F4s and Nikon AF lenses. So the speed of AF I guess is really subjective.
I use a Kenko 300 Pro 1.4x Teleconverter and have good results. It is a little softer with the TC, but the VR and AF both work (as long as there is light). This lens does hunt when it's really low light with or without the TC.
Don't know about the AF capabilities of the D100 but on a D1x I would definitely recommend the 80-400 VR lens. Good crisp photos, compact and lightweight lens that can be handheld up to 400mm.
For whatever reason I cannot attach the JPEG here, but if you will look at this page; http://www.myfotos.ws/AAD100/80400VRTC201.jpg you will see the results of an experiment using the 80-400mm VR with the TC201, the only teleconverter approved for use with this lens.
In the first, or top example the exposure was made using a 5 sec self timer delay at 1/50 sec.
In the second, the exposure was made using the anti shock mirror ON, again at 1/50 sec.
The second was obviously an improvement, but still fuzzy. Something you expect with a teleconverter, about 10% degradation, I think is what is commonly touted.
In the third, an Unsharp Mask (Photoshop) of 100 Amount was applied. This is about all I can tweak out of this combination. I'll probably not use the TC201 myself, I do require a higher sharpness standard than this combination affords, particularly for bird photography.
Neglected to note; the D100 manual advocates usage of the antishock mirror at exposures 1/2 sec or longer. I was surprised therefore, to see it does have an effect at a much faster shutter speed. (1/50 sec)
I'd be interested in getting a Kenko if this is what you say, the AF worked, and the VR as well? According to the Kenko specs, it's not supposed to be able to do that. The TC201 is costing me too much light and is too fuzzy for my needs. Can you verify your claim, (I mean just by repeating what you said)? Thanks
With the 2X Kenko Pro converter, AF will not work. VR will. I've found chromatic aberration to be very apparent with the 2X converter and this lens.
The D1x has a stronger AF motor than the D100, so you will find the slow AF performance even slower on the D100 than on the high end body. I like the 80-400, but I do not recommend using a 2X converter with it. Based on what I've seen reported for the 1.4x converter, I'll probably give one a try. I wouldn't recommend the 80-400 for most fast action shooting, an AF-S lens would be the best choice if that's your primary use.
