I have the K 24/2.8. I am looking to trade up to an A 20/2.8 sometime in the near future. (maybe, looking at trading up to A lenses) That is when I came across the M 20/4. Most probably I will not buy it. (so if someone is interested, there's one on ebay) Do you know if the A 20/2.8 is better suitable for architecture? Or should I just stick to the 24mm for a general wide angle? (maybe trade up to a A 24/2.8) L
