Here is the new JTAT SD/Nikon Mount Adapter with infinity focus

I ordered the old JTAT SD/Nikon Mount Adapter from their website

http://www.jtat.com/sd/sd_main/SD_Nikon.html

And I received this email from Masakazu Tsuboi:

1, You ordered our old SA-Nikon mount adapter and it works only SD 10.

2. Just now we are ready to ship our new SA-Nikon mount adapter working with SD15, SD1, SDm1.

3, It makes perfect infinity on Nikon lenses.

4, The new adapter cost 17,500JPY including worldwide shipping cost.

5, If you hope to get new one, please send add US $50 to our PayPal account.

I paid the addition amount and received the new adaptor and rear element depth gauge.

The total cost is USD $200.

I do not own a Sigma SD1 yet so I have not tried it.

Re: Here is the new JTAT SD/Nikon Mount Adapter with infinity focus

What is the rear element depth guage for? Are there some Nikon lenses whose rear element is too long to fit on the SDx cameras? I'd love to try the full frame 17-35 Nikon wide angle on my SD1.

Re: Here is the new JTAT SD/Nikon Mount Adapter with infinity focus

I'm interested in using other mount lenses on the SD1, but I've tried the M42 adapter on my SD15. Without liveview or a split focusing screen, I found it super hard to confirm focus. I even bought a 1.3x magnifier, but it was still difficult (I have 20/20 vision...)

It didnt help that my SD15's focus confirm was wrong. As in, the focus dot would appear, but the image clearly wasnt in focus...

Yes there are wide angle Nikon lenses who rear element protrude too far into the lens mount to be used on Sigma cameras. The depth gauge is a useful tool rather than risk cracking the IR filter.

The Sigma SD1 has a bigger viewfinder and this would hopefully assist in manual focusing. I did up a small image showing relative viewfinder sizes of the Canon 1DX Nikon D800 Sigma SD1 and Sigma SD15. The image is small but these are the actual size of the viewfinders. Obviously they'll look a lot larger with your eye pressed up against them.

From largest rectangle to smallest:
Canon 1DX 100% 0.76x
Nikon D800 100% 0.7x
Sigma SD1 100% 0.61x equivalent
Sigma SD15 100% 0.51x equivalent

Just to show how dinky and small most of our DSLR viewfinders are. Here is one with the largest rectangle being the actual size of the Pentax MX viewfinder from the 70's.

Have you tried the new adapter with a lens? Gee, I think I am going to order one right now.

Re: Here is the new JTAT SD/Nikon Mount Adapter with infinity focus

Did you get a new list of lenses that fit, don't fit, don't know? Or did you get the old one. The 14-24, and 24-70, two that should help the SD1, I did not see on the list.

Although I own a variety of Nikon lenses, from 50 up I think Sigma choices are more than adequate. It is the wide end that is needed. I have one long one, 400mm Type 1 - a beast at 15lbs - that can produce better images on the SD10 than the 500 f4.5. But trying to shoot action with it manually would be a task.

Basically all normal and telephoto lenses will work. It is the wides that are the problem hence the depth gauge. I guess you could take the depth gauge to the camera store and make sure the Nikon lens is compatible before buying. You'll have to get Nikon D lenses or the old Ais that have an aperture ring not the new G without. I disagree regarding Sigma lenses from 50 an up being adequate. All Sigma lenses bar a handful are less than adequate for the SD1. From my research at less than 100mm length the 20mm f1.8 is okay, the 50mm f1.4 is okay, the 85mm f1.4 is good and the 70mm macro is excellent.

The 20/1.8 will suck on the SD1. Most users complain of poor edge of frame performance. Wide open its not good and it has to be stopped down to f2.8 before it even begins to offer acceptable IQ and being as there are far better lenses of around the same focal length that are brilliant at f2.8 (The Leica 19mm f2.8 Elmarit R, and Contax Carl Zeiss 21mm f2.8 Distagon T* for instance) its hard to find any reason to recommend the Sigma.

LarryJ found the 20mm to work fairly well. There's some CA... I am borrowing the 20mm for a bit and will see how well it works.

I'm not sure about the 1.8 performance yet, but if you were buying it for landscapes that would not matter.

It's the 18mm that seems to have more issues.

Honestly though I think someone thinking about a great wide lens on the SD-1 should get the 8-16mm, or something like an 8mm prime and then a DP-M camera (1 or 2 or both). Those should outdo the performance of any lens from any other manufacturer on the SD-1.

Re: Here is the new JTAT SD/Nikon Mount Adapter with infinity focus

I tried to install this adapter on my SD15.
It is very easy on SD15, and easy on my lens.
When SD15 install on the lens with AD08-03. It is very hard.
But it is working very good.

Re: Here is the new JTAT SD/Nikon Mount Adapter with infinity focus

Why are focus-confirm adapters not offered? I have a dandelium from peleng8.com for c/y-eos. is wonderfully working incl. focus-trap.

I will have to open a dispute with paypal in a few days if I have not received any message from them

The worst thing is that I have four Leica R lenses (Leitax converted to Nikon mount) and other two Nikon lenses AF-D(85mm PC also) and without JTAT new adapter I can´t use them with infinity focus

I will receive my SD1 Merrill at the end of march and despite the lack of Live-view and Adobe support I like Foveon look and wanna bet on this camera and brand

Re: Here is the new JTAT SD/Nikon Mount Adapter with infinity focus

Hi:

I ordered my adapter and did receive it within 10 days or less. I received it last week. Very well made. My SD14 is at Sigma for a focus issue, so I have not tried it yet.

For your information, payment was made in 2 instances through Paypal, one for $165.00 and another for $50.00. The $165.00 payment was the price for the older adapter and shipping and the $50.00 was the surcharge for the new adapter.
Both payments were made to sales@jtat.com, the Paypal address.

Also, to communicate with jtat, I contacted Mr. Masakazu Tsuboi at sd@jtat.com who was very prompt to answer. I had also sent a message at sales@jtat.com which went unanswered, but the one sent at sd@jtat.com was indeed answered almost immediately.

On another note, the adapter came with a CD that contains a few .mov files which demonstrate the usage of the adapter. One of these files shows how to use a plastic aperture "stopper" (for lack of a better word)that one could install in a Nikon G lens (the ones that have no aperture ring with the body of the lens). A number of those "stoppers" held together as a ring is provided with the adapter along with the depth measuring gauge. I did not find the demonstration extremely clear, but from what I understood, you insert the "stopper" into the aperture lever well which forces the lens aperture to open (presumably to the maximum aperture) and you then insert the lens as any other lens in the adapter. I would conclude that would limit your usage of a G lens to its widest aperture only. I may be wrong and would appreciate if someone could correct this impression. The prospect of using the new 14-24mm F2.8 on an SD1M is very interesting, but if only at F2.8, much less so.

Again, the proper email address for contacting jtat (Mr. Masakazu Tsuboi) is sd@jtat.com
