Ron,
I forgot to tell you, you are going to laugh
Last minute..before I pressed submit button...I changed my mind and ordered 17mm Nagler instead
The reason being I still want Pentax later on, maybe after tax return.
But either 10 or 7mm, 'cos they don't have any issues like 14 and 20mm ones. And then I should be OK for long time I hope
BTW, I just realised I didn't say this in my last post...
