Yeah it does make more sense when comparing it with the other 35mm lenses. Sorry that I didnt get it at first and thank you for your continuous effort.

Ah sorry, then in that case I redid my test and found the length to be 19.4cm (194mm) and used the sensor size length of 23.6mm. So using the formula 194/23.6 = 8.22 ratio. Am I doing it right? Let me know

The vignette test wasnt done at its closest focus. So I made a picture of a 0.5cm grid paper at its closest focusing distance. Then zoomed the picture at a 100% and measured a block that is normally 0.5cm X 0.5cm and turned out to be 3.2cm X 3.2cm. Does that help?

That is so cool that you mentioned that because I also noticed the big play on my 35mm lens, but do you think it can be fixed? I thought it was because the hellicoid isnt as tight and therefore has all this play. So im not sure if that issue can even be fixed. For me it is not a big deal in real world usage and it adds that extra bit of satisfaction when making a photo. (but if I can fix it then why not)

No thank you for your amazing post, which made me discover this lens. I wanted a small, fast aperture (at least f2), cheap (sub 250eur), manual focusing (short focus throw) standard lens (30-40mm) with smooth bokeh. As MF with the Fuji lens isn’t that enjoyable. I was looking at the: - Fujian F1.7 CCTV (I didnt like the swirly bokeh) https://www.flickr.com/photos/lillemets/15173602311/in/photolist-p7QFjX-pt13EX-oNnt8x-pcdbqz-bXyyJG-kvYySR-bDeLe1-pLvkjh-s9gyTC-p71Yvc-nhxHWk-8HNKax-rN9fuZ-kvZ1DD-FfoZrY-dPXc6j-oQNNfm-bDeKbY-FFvsGM-mpjZxB-rN9gvM-qoq4Pm-dYqfkr-tvkuQ7-qSesWF-bXyHi1-oHc2Yp-oHcdS9-oZDWyE-qeTeCa-bXysdQ-gz7uZE-Fp89X1-m5d44v-bR3e7T-aBNHJe-ps5uux-oHbWUr-fU5gQ9-bF2QoJ-d8H6Yo-dEUhRk-bXyrm3-dwqgNu-aGcA3R-hVgELC-rFrRyQ-9Mxeg8-efYQan-bTWzMM - Kaxinda 35mm f1.7 (didn’t appreciate the look and the visible chromatic aberration) https://www.flickr.com/photos/s13n1/25757655603/in/photolist-Ff7HCp-GggPrA-G4wbm4-Ar7RDV-DUp929-Gkha4w-DwkLgk-DCEzZV-F5FNib-AKnUMk-E7FejR-FsiQiz-AYGrro-C33og9-FXsExs-CmSR7R-Fs89BS-GkhihW-Gc1zsb-FiSoHW-AKacdo-E3v6yh-G4Y3PP-AtqCJn-GeijEZ-CJnN1M-FeW5qu-GpqXsH-Esdh1t-GiAbw2-FtYCeb-GiAbPg-G86297-Fua9eF-AmtXtT-C33ncA-Gpr7Xz-CfqT9P-DyR2VQ-zuKZpb-BwDRCh-Geqhry-DCHpiu-G2DZSq-CWNtyj-C2ADTY-CwZnAy-GkhCim-Fj31Sk-GkheKL - Mitakon 35mm 0.95 mk2 (expensive but loved the smallish size, bokeh, wide aperture and sharpness but for night time photography was put off by the visible chromatic and comatic aberration) https://www.flickr.com/photos/peace-on-earth_org/26273268696/in/album-72157666320524710/ - Wesley 34(1.7) & Jackar 34mm (didn’t appreciate the look of the lenses) Unfortunately there weren’t any pancake lenses available in the 30-40mm f2 or faster range that I know of. And focal reducers with a 50mm didn’t produce great IQ below 250eur. Sorry side tracked. Back to your qs. The Zonlai 25mm also has 12 blades. I couldn’t find any information regarding the magnification, especially due to the focus breathing like you mentioned. The Fuji 35(1.4) is a bit wider and focuses significantly closer (28cm vs 30cm) which I can show you pictures of, but not sure how that can help you in any way * Also for the Samyang 12mm I see that the lonelyspeck and the petapixel reviews are the same. * And the recent price of the Zonlai 25mm ($125) and the 35mm ($120) incl shipping, although with the ‘Best offer’ option you could easily save off $5 on both lenses. As I got my 35mm for $105 incl.

Ok then hereby the Zonlai 35mm review

Now there is also a 35mm review on youtube for those who are interested in the 35mm lens.

Hi Quincy, there is a review of the Zonlai 35mm on youtube. Could you check it out if it is interesting to add that to the list. I think it is one of the few reviews of that lens out there. Im affraid add a link to that video for fear of the post being removed. thanks in advance
