I don't think I need to make the case for a full frame fisheye zoom; there have been many threads on this topic, and plenty of workarounds suggested to try and get the Tokina 10-17mm to work effectively on a full frame sensor.
A few years back there was talk of making the case directly to Tokina with a petition. As far as I know, this never happened. (If it did, it doesn't seem to have had an effect!)
As a result, I've taken the liberty of creating a petition with the aim of getting Tokina to see the market for this lens.
If you're in agreement, please sign away! At the same time, if you're able to write something in the comments section of the petition as you sign it (e.g. your thoughts on the lens, if you think you would buy it, etc.) that will lend it much more weight.
All the best,
P.S. If anyone with a website would like to advertise this petition and therefore make it more effective, please let me know and I can send you the code for a 'widget'. I think.
