I'm considering the purchase of a Venus Optics Laowa 15mm f/4 Macro Lens for Sony E (VE1540SFE), http://www.venuslens.net/product/laowa-15mm-f4-wide-angle-1x-macro-lens/ for use on my a7R (and eventually on an a7RII).
Before making the purchase I'm seeking the wisdom of forum members. Thoughts and comments please…
Thanks,
