Which 1.4x teleconverter for Tokina 10-17mm wide angle lens

Jim Can you share more information about this problem with the D90?

Hi Bill,

a friend sent me an email with a customer review from Adorama but for the life of me I can't find the review myself on the Adorama site.

The review stated "......Need to set exposure to -.7 to compensate, camera (D300 and D90) not aware of this teleconverter........."

I can't see any reviews on any of the DGX 1.4 Teleconverters and have emailed my friend to confirm.

Hence I'm very interested in what Scubysnaps exif data tells on his D90 when using the Kenko.

Cheers,

Jim.

In my metadata it records a focal length of 24mm on all photos (maybe a 100?) (divide that by 1.4 and you get 17mm, I reckon I must have zoomed out on some of the shots, not sure though), I was using 10-17 tokina, it doesnt mention I was using the TC.....in regards to what lens is used, all there seems to be is the tokina 10-17 f3.5-4.5, the aperture range seems to be from f6 to f22 in my collection.

On a few macro shots I used it on it records a focal length of 82mm on my Nikon 60mm...but wait there! the data tells me my lens is a 240mm f11 (lens is 60mm f2.8)???

Hope that helps, if you want me to try any other ways to inspect the data, just let me know

Hi Bill,

it appears the review I was sent was for a DG series Kenko TC.

In my metadata it records a focal length of 24mm on all photos (maybe a 100?) (divide that by 1.4 and you get 17mm, I reckon I must have zoomed out on some of the shots, not sure though), I was using 10-17 tokina, it doesnt mention I was using the TC.....in regards to what lens is used, all there seems to be is the tokina 10-17 f3.5-4.5, the aperture range seems to be from f6 to f22 in my collection.

Thanks Paul,

I guess that shows the camera is aware of the TC and the added length and effective apertures even if it does appear to give some odd figures.

Cheers,

Jim.
