    Who has the RF 34 STM and one or more of the other RF STM primes? Before I purchase it, I need to know how it compares to the other RF STMs.

    I ask because I want to know where the 24 fits in with the other RF STM primes in regard to IQ. I don't have the RF 24 yet, but I have these and I list them in the order of best to least IQ, irrespective of FL and AF performance:

    1. RF 85 f2
    2. RF 35 f1.8
    3. RF 16 f2.8
    4. RF 50 f1.8

    So where would the RF 24 fit in?

    I realize that others will rate these differently, but this rating is based on my copies.

    I'm also interested in this question. I have the same four RF primes, and would rate them in the same order as you, though I think they're all pretty good. I've had great results from the 50 F1.8 processed with DXO Photolab. For me, it's pretty sharp even wide open in the center, and out to at least the rule of thirds points. I'm certainly interested in the 24 F1.8 as well.

    Have all the mentioned lenses and also the RF 24mm
    Find it to be very close/similar to the RF 35mm, AF speed is also similar.
    Not at home so can't post good samples but I do have a link to a few images I took while testing the RF 24mm:

    The 85mm is the one with the worst AF performance (slow) but image wise it's a nice lens with a good image quality
