Btscott 3 Posted November 11, 2022 I am finding a lack of sharpness using Tokina 10-17 fisheye. Wondering how much improvement I will find with Canon 8-15 fisheye. Any opinions? Rhx! Share this post Link to post Share on other sites
TimG 62 Posted November 11, 2022 If you are using the 10-17 on a FF camera, they are pretty horrible. On an APS-C (in my case the Nikon D500), I can't see the difference between the Tokina and the Nikon 8-15mm Share this post Link to post Share on other sites
Btscott 3 Posted November 11, 2022 I have a APS-C. Happy with all my other lens, but wide angle just hasn't been great. I'm sure conditions are a factor. Just curious if other have used both and seen improvement. Share this post Link to post Share on other sites
TimG 62 Posted November 11, 2022 The 8-15mm on APS-C is nice and arguably more useful than on FF in that you do actually have a true zoom but only, I'd say, from about 11mm to 15mm. But I doubt you'd see much of a difference between the 10-17 and the 8-15. Certainly not enough, I'd suggest, to justify spending $1200 on the 8-15. Share this post Link to post Share on other sites
Btscott 3 Posted November 12, 2022 I would buy used if it shows some decent improvement. Agree not worth the $1200 to switch. Share this post Link to post Share on other sites
Architeuthis 120 Posted November 12, 2022 I use both 8mm - 15mm Canon and 10mm - 17mm Tokina fisheyes on MFT (Oly EM1-II and EM5-II). I confirm that there is no difference in sharpness between these lenses UW. The Tokina gets softer, when used with a 1.4x TC, while the Canon is still sharp with it, but without TC the IQ is practically the same... For the smaller MFT sensor, the focal length of 8mm - 15mm is the optimum, while for APS-C 10mm - 17mm is the range of choice. No reason to go for the 8mm - 15mm with an APS-C camera, except the good feeling to have a high quality lens behind the domeport, compared to the low budget Tokina (but the lower IQ of the Tokina is over the water, not UW)...

Davide DB 398 Posted November 12, 2022 Any difference between Canon 15 mm and Sigma 15 mm fisheye on a FF Sony A7RIV? Share this post Link to post Share on other sites

Wolfgang Sounds like my issue is that I have been using the Kenko 1.4 TC. Sometimes like the extra reach. Regardless, thanks for the info. Share this post Link to post Share on other sites
