Sigma 150 - bigger magnification

Think you may find that they are filter ring adapters.... Also looking at the pictures - the threads are the wrong way round.... As aren't they supposed to be on the outside of the adapter ring instead of inside...

:thinking: Why would you want to attach a Nikon 50mm to the front end of a Sigma 150mm :shrug:

I would have thought it was obvious :thinking: You do this to get greater magnification.

OP. If you are not sure what to buy why not note the diameter of the two lenses and ring a dealer up and explain what you want. I'm pretty sure that they'll be helpful and guide you in the right direction.

All you have to say is "I want to reverse fit a... to a...."

:thinking: Obviously not... Me I would've used a TC (which I had when I had a sigma 150mm but then again I had the Sigma 100-300 ex dg f4 as well so it was part of my gear)

A lot less magnification gain than reversing a 50mm onto the front.

You can get roughly 4:1 magnification.

I got a 67-52mm reversing ring from Amazon to fit a Canon 50mm to the front of my 70-200mm. Just check it's a reversing ring and not a step-down adapter.

:thinking: Well... the OP seems to have the two lenses mentioned and seems to want to use them in a sensible way... which all seems pretty clear to the OP, and to me :bonk:

yes, bigger magnification - that is what I want to get. I have both lens (sigma150&N50) so it will be cheap way to increase magnification.
I found this on Ebay, probably it is proper ring however I did ask the seller- I'm waiting for confirmation

Yep, it's described as a macro reverse ring which is what you need... 150+50mm should give you 3:1 macro, very nice!
 
Thanks 'markyd', it looks they have everything!
I already bought item from ebay as the seller confirmed this ring is exactly what I'm looking for, I should receive it within 2 weeks time:)
