Nikon to JVC Lens Adaptors Price: £185 +vat at DVinfo.net

Santos Ramos · April 18th, 2007, 06:42 PM

Just found this lens adaptor and I was wondering what would be the differences and benefits of this adaptor( http://www.mtfservices.com/ ) conpare to the letus35,Brevis 35 , redrock m2 and other lens adaptors under $ 2000.

The Nikon to JVC MTNIKJVC cots only £185 around $300.
Photographic lens is increased by almost 7x.
No ground glass.
No battery need it.
No Light loss ( I am not sure about this)

I have never used this adaptor but I am thinking in getting one.

Any comments before I buy it.
Any reasons whay I should not buy it.

Would the letus35,Brevis 35 or redrock m2 give me a better quality image?

I own the JVC GY-HD110 and I lot of Nikon prime lenses.

Without an imaging element or gg or whatever you call it, the focal length of the nikon lens is magnified by 1.5x (if I remember correctly). If that's what you want, then this is for you. But I want my 28mm lens to work like a 28mm lens and 50mm to work like a 50mm lens in terms of angle/field of view, and image distortion. Correct me if I'm wrong guys.

Kim,

I did not know about this,
So the letus35,Brevis 35 , redrock m2 and other lens adaptors under $ 2000.
Will keep my 28mm at 28mm and the JVC MTNIKJVC will increase the 28mm X 7?

But if I use the JVC MTNIKJVC the image quality would be better than the letus35,Brevis 35 and redrock m2?
I am saying this bacsue of the light loss , the ground glass and you have to keep the original camara lens to use this adaptors.

Thanks!!!!!

Santos,

You are looking totally different concepts here. The letus/brevis/redrock etc are designed to give a cine style image, some use spinning ground glass and a variety of tricks to give a close approximation of a 35mm DOF and allow the use of photographic lenses.

The MTF/JVC MTNIKJVC/ZOERK/LES BOSHER mounts are a machined converter that allows you to put a Nikon/Canon EOS/FD/whatever onto the front of your JVC. The different CCD size results in a reduced angle of view from the lens and the apparent 7.2 x magnification.

I use the MTF adaptor and it works fine for long lenses. If you want wide 'primes' then go for one of the letus types.

That sounds right. Wow, i didn't know it was 7x. Who wants that? Also I think the imaging elements in these moving adapters give it a celluloid texture to the image on top of reduced DOF. Just my subjective opinion.

Hi Guys.

My MTNIKJVC was never meant to replace the Redrock, P&S Technik etc etc.
but rather to meet a specific requirement (extreme telephoto)

With My adaptor there is no light loss but there is the 7.2X increase in magnification.

My Friend Nigel Cooper has written an excellent article on shooting wildlife on the JVC.
