    I have a gf1 for a while but had no native lenses so I got 2 adapters for pentax and olympus.I find the oly gives better bokah especially close up shots but the pentax is sharper overall. 5x6_pink_tulips_pentax_28mm. pentax m smc 28mm@2.8 [​IMG] 5x6_pentax_28mm_blue_tulips. pentax m smc 28mm2.8 5x6_oly_50_blue_tulips. olympus 50mm 1.8 5x6_pentax_iris. pentax m smc 2.8 5x6_olympus_50_iris. olympus 50mm 1.8 5x6_oly_50mm_cacti_2. olympus 50mm 1.8 5x6_pentax_28mm_cati2. pentax m smc 28mm2.8

    Hi Nikki,

    I just tried the Pentax 28mm. My copy is an f 2.8. I found it a little lacking in contrast but it's possible it performs better when stopped down.

    I did note that close in it was quite good, getting out towards infinity it seemed to lack crispness.

    I tried a MC Rokkor 28mm this week, also f 2.8. I think I might be enjoying the Rokkor performance a little more than the Pentax.

    Pentax: https://www.mu-43.com/f81/pentax-28mm-2-8-smc-pentax-m-k-mount-image-thread-11909/#post104959

    Not close to exhaustive... but I have many more sitting on the drive which I've already perused.

    The rokker seems very nice,I tried to buy one last week but they would not sell it to me without the minolta film body so I didnt take it ! I also noticed the contrast issue with the pentax when shooting buildings but as it was the first shot with the GF1 i thought i just had the settings wrong:smile:

    I'll tell one thing for sure. Using the manual focus lenses reminds me why the advent of auto focus was such a breakthrough.

    The panny 20mm on an µ43 body is among the nicest camera lens combos I've ever owned. If you can find one, and afford it, buy it immediately.

    I did own lots of Rokkor lenses through the years, and always felt they were very underrated in their day.

    The Pentax does make a more compact package on the µ43 body, the Rokkor is a little longer.
