Hi to all. I recently purchased a Nex7 as a platform for using alt. lenses. I have purchased a few interesting lenses to cover my needs in terms of focal length and speed, but there is one focal length that is important to me that remains uncovered: 28 mm (40ish equivalent).
I have considered the G Biogon 28 (apparently there is no discussion about the color shift and border smearing being present with this lens) and the Zeiss ZM 28/2.8 (seems like results arenīt much better with this one either).
I understand that the problems are present only with rangefinder-symmetrical design- lenses, and it seems like the bigger SLR counterparts are free (in most cases) from this aberrations.
But before I give up and settle for one of the (bigger) SLR possibilities, I would like to ask the members here about one last RF lens that I am intrigued by (and that have the chance to buy at a reasonable price): Konica Hex M28/2.8. It seems like a very highly regarded lens and I was wondering if anybody here has any experience with this lens when paired with the NEX7. Will this lens also be affected by the mentioned problems? Can anybody provide any info regarding the optical design of this lens?
Thanks in advance for the kind replies, I will be looking forward to your input.
