Raynox 150 on 18-135??

The DA 18-135 specs say it has a maximum magnification of 0.24x but I don't know if that's at the long end or at the short end, therefore I can't estimate what its max mag will be with the Raynox 150 (208mm).

I'd appreciate your telling me either how the Raynox 150 works with the lens or if the lens' max mag is when it is fully extended.

Thanks,

Dave

Max magnification of the lens natively is at full extension, 135mm. I have not tried it with a Raynox.
Note the lens filter size is 62mm, not sure if that affects how a Raynox is mounted.

Thanks a lot!

That means the max mag for the Raynox DCR 150 on the 135 is about (1.24)(1+135/208)-1= 1.04X

So a Raynox DCR 150 would be a nice addition to the 18-135 as it has a working distance of about 8" and about the max mag that is reasonable to hand-hold.

A Raynox DCR 250 will have a max mag of (1.24)(1+135/125))-1=1.58x with a working distance around 5"...not bad but I'd prefer the longer working distance. Greater than 1x isn't easy to hand-hold.

The max filter size for the Raynox clip-on is 67mm so it'll fit the DA 18-135.
