Sharing some exiting news about lenses for the AF100

I just found out this evening when doing research for my blog that you get a far smaller conversion ratio if you use Nikon DX lenses or Canon EFS lenses.

The conversion is as follows...

Nikon DX lenses = 1.3x

Canon EFS lenses = 1.23x

This is very exiting because Nikon do a 17-55mm f2.8 DX lens which converts to 22-71mm f2.8 plus a Nikon G to mFT adapter...you have the perfect all round lens for the AF100.
 
17mm is still 17mm. If you are using 35mm still frame as your point of reference, no matter what the size of the sensor, 17mm is 17mm. And on microfourthirds it will frame like 34mm, and on APS-C will frame like 28mm

However, if your frame of reference is APS-C sure it "converts to" 22-71mm f2.8. but in reality it's no wider than a Full Frame 17mm lens. Perhaps less distortion though!
 
not this stuff again, a mm is a mm is a mm. m4/3 is the smallest of the large sensors and all lenses will cover (except those for small sensors, 16mm, 2/3 etc) Field of view on a 17mm Dx lens will be exactly the same as 17mm on a m4/3 zoom. The quoted numbers refer to the slight difference in size between canon and nikon sensors, not conforming to a true aps-c standard.
 
Nooooooo...

This persists longer than Big Foot, Atlantis, and the Bermuda Triangle.

Good shooting and best regards,

If you use an adapter by a company called MTF (UK) you get full manual control of the Nikon lens via the adapter. Why are you chaps so sceptical everyone over in the UK wants a perfect fast lens on the AF101 (UK) 100 (US). It was a mount engineer that gave me the calculations on these lenses. What you are not taking into account is that the conversion ratio is less on the DX lens this is very important when trying to get a fast WA zoom lens. I have tried a 17-40mm Canon L lens on a G2 with a Kipon adapter and your lens converts to 34-80mm f4 lens due to the 2x ratio via the mFT sensor.

I couldnt see the DX to 4/3 adapter on the site. Is it an electronic adapter?

It would seem to me that it will be difficult getting a "perfect" zoom lens for a cine camera when using zoom lenses designed for still cameras. You may or may not be correct with your conversions but that aside.

At best... the "still zoom lenses" will be good as variable primes and thats something in it self. BUt...if you need to zoom... you will need a cine zoom lens.
 
OK technically we should be using PL for the AF100 but at $5K to $16K upwards it's not an option for many people so I refer to a manual zoom lens. It's not as sharp as a Nikon prime lens but a wee bit more convenient if you want to avoid changing lenses all the time. The adapter is made by a UK company called MTF it's a manual adapter and uses Nikon G to mFT. Google MTF adapters.
 
The Nikkor 17-55mm f2.8 DX lens will certainly be a good lens for the AF100, provided you get an MFT adapter equipped with a aperture ring to control the iris of this G lens.

It will offer the same angle of view as a hypotetical 34-110mm lens on a full-frame camera.

So yes, a very usefull range, with decent speed. It is a sharp lens, with an all-metal design. Just add some gears and you're set.

I have used this lens on my Redrock outfit, and it worked like a charm.
 
Nikon unlike Canon have left the leaver that activates the iris that is how the MTF adapter works...I have used an MTF Nikon G to Sony E mount on a VG10 and you can manually adjust the iris via the adapter.
 
Hey HDWarrior, so if you use that MTF adapter on the 17-55mm. Now you can control iris but will you able to find out what F-stop you are on?
Or it is a blind guess.
Thanks
 
I just bought the adaptimax m4/3 to nikon adapter and it seems top notch. Plus it uses a thumbscrew which is way more precise and durable when changing aperture. It even give more accuracy to lenses with the aperture ring since it is infinitely precise...where the ap ring is usually in full stops.
