Cross-posting some photos. I use the hood from my Ultron 40mm SLII on my new Septon 40mm because I think it looks nicer and get even more compact. The Ultron came with an auxiliary close-up lens that I never realy used, since I have two F-mount Micro-Nikkors, but now I tried it on the Septon and realy like the results
I realy like the Septon on my Zf, it's sharper at the focus point than the Ultron which is important to me. First three photos are at F2.0, the fourth at F5,6. SOOC Jpegs, only resized.
