Building the smallest M42 set. Need recommendations for a 28mm.
2017年5月5日 · It is one of the smaller lenses on my shelf and my smallest 28mm overall (length x diameter). Much depends highly on how one defines small.

2011年11月2日 · The 28mm focal length corresponds to about the same perspective as the human eye when it's used with and aps-c sensor, so it's pretty useful from that point of view. It can be useful for landscapes, particularly where you don't want to include acres of boring sky (though often you'll want something wider, I suspect).
Is this Prinzflex 28mm really worth that much?
2012年7月13日 · It's a bit of a strange design at the front because the front glass is not that large in diameter to many other M42 28mm designs except that the Prinzflex design simply screws on a wider front rim.
