Nikon 24-35mm Macro lens as Relay Lens for EX3

[Kenny_G]

I wonder if a Nikon say 20 .........35mm Macro lens will be suitable
as a relay lens for any 35mm adapter. Does anyone have an idea?
If I remove the stock lens of the EX3 and put on a wide macro Nikon lens with
for instance the Adaptimax adapter can a for example a SGBlade 35mm adapter work with it?

Hi Kenny,
I have Ex3 and SgBlade, with the nikon adaptor. With the stock lens, I m at 40mm, z70.
So a 40mm lens would be good, the voigtlander 40 f2 per example.
BUT, I think there is a big issue. I test all this, and the stock lens is sharper than any of my Nikon lenses. Nikon lenses have some big flares with the EX3 too, I don t know why.

I think 24x35 lenses are not made for this size/density of chip.

I can't tell you if using a normal prime lens in this way is possible, but I will give you my two cents anyway...

There are many benefits to using a relay lens in conjunction with a 35mm adapter, but one of the major pluses (for me, anyway) is the ability to lock the focus down, so you need never adjust it again. You can't do this with a "normal" lens.

Also, the fastest affordable Macro you're going to be able to get will probably be around f/2 - f/2.8 - That's quite a bit slower than the EX3's stock lens.

Sure, relays are expensive, but why not just save up? You'd feel a lot better in the long run.

I am "saved up". When is Letus going to release the rely for the EX3? NAB? They don't have a booth so I'm not holding my breath for that.

Philip Bloom made a review of this lens relay on his blog. Apparently, it s made for PL lenses, academic frame (smaller than 20x36), so we wiil have some crop factor.
It 2 stop faster.

Just one point about Nikon lens : you don t need any macro lens, the accromat does it job.
I think the focus distance is about 45cm with the stock lens.

For the lens relay....April ? 3000$ ?

I think these are the benefits:
2 stops faster (huge)
rig's weight
rig's length

sharp edge to edge ? Do you really focus on the edge of your frame ? for 500$, yes of course, give me this edge to edge sharpness, but for 3000$...

Have you guys tried using a reversal ring? Its a 52m threaded ring that screws on the front of your nikon lens and allows you to mount it backwards. The result is a macro lens, razor thin depth of field and the focus ring becomes useless. I wonder if this can be used in some way. Its called a Nikon BR-2. Used on your 50mm F1.4 you have a super fast macro lens.
