Re: New 1.4x Lens Test Results Online

I'd just like to thank lothman for asking this question, because my 7-element Scanner-Nikkor ED lens was not performing as I expected on APS-C and after checking... yup I had it backwards (dot was facing subject). Flipped it around with dot facing sensor and it makes a world of difference at 1.4x o...

Re: Advices for enlarger lens

That is called a thread gauge here, not sure there, but I can never find mine, and I have more than one, but I always know where I can find a ruler and my phone. :D Also with the picture method I can ...

Re: Advices for enlarger lens

Thank you Robert, I hope to find it also here in Europe. You are a lot closer to RU (Raf) then I am, for me they are almost 10,000 k away from me :D So, there are 2 ways to go, with the 0,75mm (T2, SVBony..) and with 1mm (M24..). But how is about the step up / down rings? Then, I already have the 6...

Re: Advices for enlarger lens

Thank you very much for answering. My camera is an aps-c sensor one (Canon 60D). I'm interested at the moment for magnification from 1 to max 4. Testing now magnification from 2 to 3.5 reversing the canon 24mm f/2.8 stm pankake. I published my first tests here https://www.flickr.com/photos/19187552...

Re: Advices for enlarger lens

One more? 100.jpg The 5.6/100 CPN-S is another recommended choice for a TL due to low cost, I have picked up copies of these for less than $50 in the past. Slightly more CAs than the CPN-S 135 but sharpness is good. I might have an extra copy lying around. https://www.closeuphotography.com/componon-...

Re: Advices for enlarger lens

:shock:

Forgot about this one! I forget about tests on my own site!! #-o

In a lot of cases the CPN-S is cheaper than a Raynox and makes a super portrait lens also, where the Raynox is horrible at infinity.
