Hi Carlos,
Thanks! Those are the options I knew but don't fit my search:
I already got the 36-72 series E zoom for using it at 36 f/8-f/11...
About the CV40, I know with it I couldn't get enough DOF... Not as much as with a 28/35 at the same aperture, I mean... And the angle is a bit too closed for "being there"...
About the CV20, it must be nice, but apart from being too wide, I use the Nikkor 20mm 2.8 and like its close correction, and stopped down has nice sharpness/contrast, so getting another 20 would be too much...
As I own 20 and 50, the middle point to think of is a 35: I thought maybe some third party manufacturers could have made a small slow 35 for Nikon in the past, but perhaps it's not easy to make it small for SLRs, or maybe few people would buy a slow lens... If I could find one no faster than f/8, I'd get it immediately: I guess it would be possible to make it small and with a not too close MFD... I've also been about to buy "for years" the 35 AFD, but with the oily blades tales and the poor sharpness and sample variation tales, Yet I have no 35! I hope one day I can get a small one...
Cheers,
Juan
