Schneider on Fujinon?

[Charles Barreto]

Does anyone have or use a Century Precision Optics 2x Extender 1/2" Bayonet Mount on their GY-HD100. I was wondering how it performs...light loss? Can a subtle Depth of Field be attained?

[Tim Dashwood]

I haven't used it but I can tell you that an extender won't affect your depth of field other than change the effective focal length and aperture. Also, you would need the ACM-12 to adapt to 1/2" for use with a 1/2" lens.
I believe a 2x extender will double the focal length yet reduce the usable aperture by 2 stops.

I sure hope this is not the case as I asked the Schneider Rep about needing anything else and he told me that the 0XF-212B-00 model just attaches to the camera body with no need of anything else. It would stink if this is not true as I just ordered this part and adding another $700 for the ACM-12 adapter would not be cool !

Not only will you need an ACM-12 but you'll also need a 1/2" bayonet lens! If you are buying a ACM-12 and a 1/2" lens then you can likely find longer focal length lenses anyway!

BTW, I read the Schneider literature about the benefit of "shallow depth of field" and I just need to tell you that yes you will have shorter depth of field, but not as a result of some magic design in the adapter. The laws of physics/optics are simply at work and if you double the focal length (which in essence is what an extender does) then you will have half the depth of field. Keep in mind you will also half the angle-of-view so don't plan on shooting any wide shots without removing the whole rig and putting your 1/3" 5.5mm lens back on.

If you need telephoto ranges I would recommend exploring used 2/3" lenses with long focal lengths and purchasing the ACM-17 adapter. Alternatively you could also look into the Nikon adapter and cheaper Nikon SLR lenses.

Also, there are now some wide range 1/3" lenses from Fujinon and I believe the latest one has a 2X doubler built in.

Hey Tim..you are a life saver..I called the Rep at Scneider and he was like "ooops...my bad" but he said he had the perfect solution that did not need the ACM-12 adapter. Would you ve able to verify for me if this makes sense?

thanks a million

[Tim Dashwood]

Yes! That's the one you need. It will work with the stock 1/3" lens - no adapters needed.

Thanks Tim...great info and knowledge to tap into.
