This looks very exciting for those of us shooting landscape astro. The use case is clear.
After being burned by the ZhongYi 30mm I will wait to see reviews but this will probably be on my shopping list if coma performance is close to their marketing.
It's likely to be a rehoused version of the NiSi 16mm T2.9 65 prime (USD2800) which is already a known entity, but will wait and see.
Edit: it's already in stock here in Aus for AUD2099 (USD1470). I'm tempted since returns process will be easy in Aus.
After a week in the mountains, this is a cool bit of news to return to. I'm a little unclear on filters, is it only when stacking vignette is an issue? I would be curious to know if the Kase inlaid magnetic ring would work and stay with 82mm filters (which I already have). But hard to see from pics if it would hit the front element.
Buy it Thrice and report back, please!
