Tokina 10-17 too wide. Options?

The downside of both the Sigma 17-70mm and Tamron 17-50mm is that they both extend a lot while zooming - which makes them more troublesome to house. The 17-35mm is internal zooming.

A-HA! Good to know. Maybe I'll just have to save a bit longer to swing the 17-35!

I just spent 3 weeks shooting with the 17-70 Sigma in Palau. I was shooting manta's, sailfish and eagle rays between 24-29 mm. 17mm was way to wide.

Overall I'm not so impressed with the sharpness of this lens compared to my 60mm. On the last day I used the 60mm to shoot mantas. I got some really nice closeups of their gills when feeding and some really good headon stuff.

Could someone please show me some examples of the Tokina with the Teleconverter? I am interested in exploring the possibility for my trip to Lembeh in a couple of weeks. Which tele should I get? The Kenko? 1.4x? Its to be used with a D300.

I also have a 60 macro too but it is the new AF-S model. Someone mentioned that the Kenko TC will not work with this lens? I thought Kenko had a version that works with AF-S lenses....

What about the Nikon TCs that work with AF-S like this 1.7x?

does this mean it wont work with the Tokina 10-17?

Sorry for the newb questions but I am completely new to TC use and just know the basics (loss of light), etc.

I have tried it, but don't love the effect. The light loss definitely harms AF performance. This shot, not great BTW, was done with the Tok 10-17mm @ 17mm on 1.5x TC:

I think the fisheye + TC technique is fine on lenses which are F2.8, but less good on slower lenses from this practical perspective. Furthermore I cannot zoom my Tokina once it is on the teleconverter. Some housings will allow this - I know the Ikelites do. So for the example above I had it on the 17mm end to get something different from using a 10.5mm on the TC.

Thanks Alex. I guess I will just have to wait and see Inon's future offerings.... my interest in this subject came from seeing a report on their prototype Fisheye macro lens. I hope they go commercial with it and that it will fit housings from other brands too!
