Nikon 105 VR with 5T or 6T

I've no experience with that lens. The two mid range zooms I use are:

17-55mm F2.8 - behind a dome port, with a dioptre.

28-70mm F2.8 (sigma) - behind a flat port.

From personal experience, I would not go any wider than a 35mm lens on FF format (about 28mm on cropped sensor) without a dome port. I think that the 24mm might be a bit compromised.

Alex,

the 24-85 has a macro setting that decreases the zoom to 35-85 and allows focusing to 8 inches.

I was thinking this zoom range would be helpful in places like the Lembeh Straits with a flat port.

Plan to try this lens out next month at Cayman Brac

Jim,

 

Another problem is that the internal diameter of the Subal extension rings is too small for the 17-55 and 105VR lens.

 

Elmer

Jim,

You are 100% correct, subal make a special enlarged ring for the 17-55.

The 17-55 works fine with an unmodified Subal extension ring and a dome port. All you have to do is mount the ring to the housing (the one I use is 60mm), put the camera in the housing, and install the lens through the ring (it is narrower in the bottom and goes through the ring fine).

I replaced my old 105 with a new 105 VR and instead of buying a new ring for it I decided to modify the one I used on the old 105. Since buying the new one would make the old one obsolete I didn't worry about it. What I did was take it to a friend that has a lathe, then he increased the internal diameter of the ring by 1mm and now the new 105VR fits through it perfectly fine, and I saved some bucks.

Any experience using a 24-85 f 2.8-4 with a flat port as a 35-85 in its macro setting??

I have used the 24/85 on its macro setting with a sea and sea set up, the ports I use are the NX Zoom port (51101) and the SX extention ring (50261) the shorter of the two extention rings. but I'm not sure if there is room to fit a dioptre on the lens, when zoomed out to 85 its close to the ports glass, I'll try and check this out.

dont know this guy but for those looking for a 5t 6t, and you are a nikonian:

And if you're not a Nikonian but you do want to get one, you can buy them here for 60 euros.
