AstrHori to launch RF 25mm f/2.8 2x-5x Macro Lens for $249

[Canon Rumors Guy]

Chinese manufacturer AstrHori is bringing another niche and cool lens to the RF mount, this time in the form of an RF 25mm f/2.8 2x-5x Macro lens. While you can still use the MP-E 65mm f/2.8 1x-5x Macro lens on your RF camera, it’s still a much more expensive way to go. AstrHori 25mmF2.8 2X-5X

Not having 1x magnification is a dealbreaker for me. I went full frame to be able to get a wasp horizontally in frame with the MP-E

I wish I would have it but right now the 200-800 is on the "top list" for me. And then 24-70, 70-200, to complete the "trio" and 10-20 for "quadra" that will be the BEST ever bag.

Exciting time for us Canon users!

The MTF values at 5x are a joke. OK for a toy with large magnification but blurred details.

I\'m afraid the diaphragm is fully manual too...

I ask myself how they did get the jumping spider to sit still until the got this lens manually focused. Maybe they cooled it in a liquid nitrogen freezer down?

I mean...5x magnification for $250....you have to take it for what it is. If you need better performance at 5x, you gotta spend more $$$. Should not be surprising.

For that price it could be quite fun.

A cheaper 5x prime would give decent images.

You set the focus, or rather magnification and then move the lens till the subject is in focus. That’s what I do with my MP-E and I don’t drug or cool any of the jumping spiders I takes pictures of.

Is there a cheaper prime 5x macro out there? I might like to try that.

Probably an M42 mount microscope objective adapter.

Probably an M42 mount microscope objective adapter.

Then all you need is a microscope objective, or a whole microscope. Personally, I have a Zeiss Stemi DV-4 Stereomicroscope and a basic Fisher compound microscope for personal use, with adapters to fit an EF mount to the eyepiece. The Zeiss Stemi is a fun little scope that goes up to 32x.



That reminds me, there was a little series I meant to post on the Fungi thread with the same subject shot with the M6II adapted to the 100mm Macro, the MP-E 65 and the Stemi. I just posted it here.

I shot in Europe here and there some zebra jumping spiders with my EF 100mm Macro and extension rings with AF, but I had to act really fast. There is a short moment when they seem to be stunned by the reflection in the lens, I guess it could be the mirror image of themselves, but that's usually a not much longer than a second. I keep your technique in mind, when I buy an MP-E (I were several times very close to hit the buy button). With a fast fps burst it should be possible to get keeper images more easily.

Good to see the lens dammed just from MTF charts... ;-)

Fortunately, I have one here to test so I can look at the actual images I get from it.

A quick test with the lens on an RP [at 5x and f/5.6 on the lens ring] and with a stackshot rail suggests it could be good value for the money
I'll be sure to check how it compares with my venerable MP-E65 ;-)

The only question I have really is which performs optically better, this or the Laowa 2.5x - 5x Macro.
