The Mitakon Zhongyi 20mm f/2 4.5x doesn't seem to get mentioned much in comparisons or elsewhere. I have had surprisingly good results with that, but curious if the Laowa or other (Nikon shooter) would have any advantages...

I must have really bad luck, the Mitakon Zhongyi 20mm f/2 4.5x Super Macro Lens that I tried had super bright lateral CAs. I boxed it back up and returned it the next day. It was even worse than the Olympus Zuiko auto-macro 2/20 that I owned.

Lou has had good results with his Laowa 25mm I think.


Some info here on the forum:

I did test the Laowa 60 2x here:

Yes, I really like my Laowa.

I vaguely remember that the 4.5x was also an engineering failure, that was supposed to have a range of magnifications but ending up with only one end of the range being usable, so they changed the specs. I am not sure if this is the lens from that story, though.

Well even though this was my first extreme macro (ever!), I think it shows the lens is good enough to keep (and I've done so, with equally good results).

Looks good at this size, and you picked one heck of a challenging subject!

Oh, he was very cooperative (having died and laid himself to rest on my studio laptop ;-)).
There are definite issues when I zoom into the uncompressed, full size version, but some of the problems I see are related to my stacking technique.. Anyway, for $200, its a keeper lens.

I got the new version, mainly to use it in the 1x - 3x range.

However, I did a quick test, comparing its performance at 4x magnification (on a FF camera) against a Nikon CFI S Fluor 4x/0.2

Some samples below, unprocessed (except for WB), single shots straight from Lightroom.

The best performance is obtained @f/4 and, and while it can't compete with a good microscope objective (as expected), I believe that the quality is acceptable.



And these are 100% zooms of the highlighted area:

Not too surprising, though that is a different model than the one I have, which is the 20mm 4.5x.

Is there a market for a 5x-10x lens? If so, how much would people pay?

The designer of a specific... ehhh, let's just divide-the-range-by-two-lens will be able to make one, he just doesn't know if there's a wider market. I'd love to have one, but I'm afraid that's ultra niche territory.

I would love to see more sample photos taken with the re-engineered version. 4x magnification was bit better than i expected.

I'm not sure it's niche as much as pushing into a different genre. Maybe I'm wrong but isn't 5x towards the limit for handheld usage? It kind of seems like they'd end up making a photomacroscope more than a normal macro lens.

Yeah many who purchased the 2.5-5x that's not as involved will constantly talk about how they can't get any results in the groups I'm in, 100% of the time it's their lack of shooting technique and will to learn. I can't imagine one that goes to 10x. It's gonna sit on a studio setup, where subjects are usually stationary. I don't think the general population would invest that much time and money into such a feat, as much as I'd love a 5-10x lens.

I won't call the 2.5-5x a normal macro lens either. It's a decent lens for inspection purposes too. A normal macro lens would only go up to 1x in my book.

Revision 2 of the lens... I'll be nicer here.
My take away of this video would be... they need a "Rev 3.0".
If I'm optimistic, third time's the charm...

with extended holidays, finally got some time to do some work. But today a big BUG caught me, spent 2 hours debugging it, it turns out at 1:1 with Zhongyi Super Macro Mk II, magnification is NOT 1:1, it is 1.16:1, or 1.16x. I thought I had some bug in my software and it is "good" for others to be aware of it, instead of pulling your hair out Very Happy Very Happy

Here is a video about it
