XL2 with Nikon Primes!
 
8 Attachment(s)
Just recieved the Novoflex XL-Nikon adaptor from B&H.
It is a very well constructed and engineered piece of solid metal with a nice
Nikon lens release mechanism.
Beautifully finished in either powder coat or anodised aluminium - I don't know which.

Shown in the photos are:

Tokina 28-80mm f2.8 Zoom
Nikon 85mm f1.4
Sigma Fisheye f2.8

A quick test in the backyard proved the combination of 35mm SLR lenses and the XL2 to be a vastly superior image than the stock Canon 20x XL lens.
Even with the 7.2x magnification factor, the image quality is simply so superior and the bonus of full manual control with nice full-throw focus on the barrel is hard to beat.
I would definitely recommend this setup for anyone with a need for full manual control if you can live with the massive focal length magnification.
It sure beats paying $$$$ for the Canon manual lens, and most people have some decent SLR lenses at their disposal.

I mostly shoot concerts, theatre and rock bands, so the 7.2x magnification is actually an advantage when shooting from the back or middle of the auditorium.

I highly recommend the Novoflex adaptor if you have some Nikon lenses lying around!!!!

You has video?

Martin Catt September 8th, 2007 07:13 AM

I went looking for the adapter on the B&H site, but couldn't find it listed. Do you have a B&H stock number for it?

Thanks;
Martin

Paul,
I would love to view some footage taken with the fisheye lens with 7.2 magnification! Problem will be you get approx 100mm focal lenght, so I dont think the fisheye effect will show up in any way?

Paul V Doherty September 9th, 2007 10:21 AM

Hi folks,

OK I'm rendering some footage in FCP as we speak.

I made some test shots of a static scene (Virgin Mary grotto in my Mum's garden!) at different focal lengths. Will post stills shortly.

Thanks Chris for finding the B&H link!

I can't commend the Novoflex adaptor highly enough - it is built rock solid with reliable German precision!!!!
Well worth the ~$200-250 (with shipping)

XL2 with Nikon Primes - Frame Grabs!!!
 
5 Attachment(s)
Ok Here are the frame grabs from FCP, with "Bronze" preset applied in Magic Bullet and matted to 2.35:1 coz I like it that way :)

Sorry they're just raw 720x576 anamorphic exported direct from FCP:

1) Sigma Full-Frame Fisheye (don't know the focal length - probably around 15 or 16mm)

2) Sigma 20mm f1.8

3) Tokina 28-80mm f2.8 Zoom @28mm

4) Tokina 28-80mm f2.8 Zoom @80mm

5) Nikon 85mm f1.4

Statue is approx. 2 feet tall. Tripod was approx. 8 feet from statue.

N.B. The visible difference in quality from the Nikon prime to the other lenses is marvellous. The Sigma 20mm f1.8 comes close though.
All lenses were stopped down to around f5.6 in order to achieve shutter of 1/50 sec. @-3dB gain in overcast daylight. Manual white balance performed with each change of lens.

Scott Lovejoy September 10th, 2007 11:26 AM

Sorry, I'm still a bit naive about things, so I hope someone can answer these questions:

1) Those shots look squished, almost like 16:9 footage shown at 4:3 without letterboxing (a la fullscreen).

2) What would an adapter like this do for DoF? I would guess that the effect would be minimal (a mini35 or m2 being the desired effect).

Answers welcome, thank you.

Hi Scott. No real impact on DOF. The posts before that mention changes in focal length due to use of this adaptor are not accurate. The lens focal length is fixed by its geometry and this does not change just because an adaptor is fitted. What does change is the field of view, which is much narrower than what you would get with the same lens on a 35mm camera and this is why it gives a zoomed in effect but without the shallow depth of field of a long lens.

Paul V Doherty September 11th, 2007 01:29 AM

I don't believe anyone in this particular thread stated anything remotely like the notion that this adaptor somehow magically gives you 35mm DOF and magically changes the focal length.

The 7.2x focal length magnification *is* mentioned many times. This is the *opposite* of stating that you get the full glory of 35mm FOV with the adaptor.

Put these Nikon Lenses in perspective: the top-shelf Nikon 85mm f1.4 prime is not as long as the stock 20x at maximum zoom, *however* it does give you an apeture of f1.4 at 85mm - something the stock Canon lens can never do. This will give you much narrower DOF than the stock lens.
Also, the *real* advantage of using top-shelf SLR lenses is twofold:

1) Top-shelf Nikon glass is infinitely superior to the stock Canon 20x
2) Most Top-shelf SLR lenses have *very* nice manual focus rings with nice long throw

Lastly, I did clarify already that the frame grabs were 720x576 anamorphic and matted to 2.35:1 - hence the "stretched" appearance.

Hope this clarifies the situation!!

Scott Di Lalla September 11th, 2007 07:06 PM

This may be a silly question. I have a bunch of lenses laying around from my F3 film camera. Does it have to be from a digital camera or can I use the film camera lenses?

Kevin Randolph September 11th, 2007 07:52 PM

lenses that you used with your F3 would be fine to use.

Paul V Doherty September 12th, 2007 12:57 AM

*Almost* any Nikon F-mount lens can be used.
That means virtually any Nikon lens made since the 1950's!!!

There are a few rare exceptions of Nikon lenses which have rear elements that project too far into the camera body for use with the XL2. These lenses cannot be used with most Nikon Digital SLR's and some film cameras either - they require a mirror lock-up feature so that the rear element does not smash the mirror!!
It is doubtful you will encounter these lenses in day-to-day scenarios.

You *can* use specially designated "DX" lenses made specifically for digital SLR's, however because they have no apeture ring on the lens (called "G" lenses by Nikon - other manufacters have other names for the same design) you will have to manually force the apeture open by stuffing a bit of paper into the apeture lever on the back of the lens. I have used my Sigma 12-24mm DX lens on my XL2 using the stuffed paper method in the apeture and it works nicely.
The reason you can use DX lenses is because although a DX lens only covers about 75% of the image area of a full 35mm film frame, the 7.2x magnification caused by the even smaller 1/3" CCD on the XL2 easily crops out the smaller image circle produced by DX lenses.

Just remember to remove the paper from the apeture lever when you want to use that lens on your digital SLR again!!!!!!!!

Be VERY careful when attaching any non-stock lens to the XL body!!!!
Watch out for two things:

1) The rear lens element must NEVER protrude so far as to come into contact with the glass covering the CCD block
2) Metal parts must NEVER come into contact with the XL mount electronic contacts inside the XL mount. I have heard of XL bodies being fried because of short circuits in the lens mount caused by non-stock lenses. (Actually it was Quyen who fried an XL during the development of his LetusXL adaptor - I have one and it's brilliant!, but I'm always careful when attaching it to the XL mount)

Hope that helps!

Michael Krumlauf September 30th, 2007 11:28 AM

Does this adapter have any magnification to the focal length or do u get 50mm from a 50mm lens?

Martin Catt September 30th, 2007 01:10 PM

No. A 50mm lens would give the apparent focal length of 360mm on the XL2 because of the smaller CCD size compared to a 35mm frame. Rule of thumb is to multiply the focal length by 7.2 to get the apparent focal length.

I have used a Canon XL-NIKON Nikkor adapter for years to bayonet my vast range of Nikkors to XL bodies, and would certainly be lost without it.

There are a few different companies making them, in either plastic/hard-resin components or metal. By far the best are made of solid metal.

The one that I have always used is made by Les Bosher - a camera engineer who has been working for film/video/television for around 25-years.

http://www.lesbosher.co.uk/

Les will also make special mounts to fit most other makes of lenses such as Pentax/Minolta/Contax/Zeiss etc.

Could you please send a video made with the adapter to my email because i just about to buy the xl2 just for the adapter. Email:mail@danielk.plus.com

Daniel Kucharski December 29th, 2007 06:45 AM

hi
 
i never really understood does the adapter effect the DOF?

Paul V Doherty December 31st, 2007 12:06 AM

Daniel,

I'm on a slow satellite uplink for the next 5 months. I'm afraid I can't upload any videos - sorry :(

But I CAN vouch for a Nikon-XL adaptor - the results are worth a few hundred dollars for a quality steel or brass adaptor. I don't recommend plastic adaptors.

There is no gain in DOF with a Nikon-XL adaptor. You will still get the same DOF at the same focal length as the stock 20x Canon XL lens

I had an XL1 as my first camera, and it served me well. I have now upgraded to an XL H1, skipping the XL2 step. I purchased an XL to Nikon adapter from RSB Film in the UK, but they no longer carry it as an item. I was using a Nikon 80-400mm, Sigma 400mm APO Macro, and an old Tokina 80-200 with the XL1, and I was very satisfied with the results. With the XL H1, I have used the same lenses with mixed results. The Nikon 80-400mm falls off at about 380mm, the Sigma 400mm is tack sharp, and the Tokina is also very sharp. I am currently using the Tokina 80-200mm as my work horse lens, and I have coupled a Nikon TC14A (1.4x) with it, which gives me an effective ~2000mm. This combo has worked out very well for me, and so far has produced very sharp and crisp video, even after being down converted to standard DV. Attached are a few images that are video frame grabs from a down converted source. All the images were shot using the Tokina 80-200mm coupled with the TC14A, including the macro shot of the fly.

For reasons I don't understand, I have had trouble uploading videos on this site. So, if your interested in seeing videos shot with the Tokina combo, go to this site.

Any video with the user name dond, is mine. Most of them are 16:9, but when they are first displayed, they show as squished 4:3, so click the resize button (blue square) in the lower right corner of the viewer to display right aspect ratio.

Michael Sweeney January 5th, 2008 03:24 AM

so what is the real point of this adapter? seems that it would work mostly for wildlife videos because of the huge magnification and such. i was very interested at first because i am looking for something such as the redrock m2 to use slr lens.

John Welsh January 5th, 2008 06:33 AM

7.2x
someone knows what is the multiplyer on 35mm adapters?
