    Anyone have the 25mm f/1.4 and e-m5 combo? I have the 20mm, though it's a nice lens. I feel that the focusing is too slow. I'm wondering if the 25mm is a big improvement speed wise? I also have 45mm which I rarely use. I'm thinking of selling my 20mm and 45mm and just get the 25mm.

    The PL25 is one great lens and the focus speed difference is one of the main differences between the 2 lenses IMO. I would suggest reading through some of the other threads here about the issue though, this question is very common.
    Here's one:

    The 25 is a significant improvement over the 20 in terms of AF. It's roughly equivalent to the 45.

    Another vote of confidence for that move. As good as the 20 is, the 25 is definitely worth the upgrade.

    I sold my 20 for the 25 and am not looking back. The added size is well worth the speed and quality of the lens.

    I have 2 boys. I'm always frustrated when trying to focus with 20mm. Then 45mm is just too close. I used to have the sigma 30mm f/1.4 on my canon and love the bokeh both in photos and videos. So i guess the 25mm is the equivalent.

    Fourthed? Fifthed? The 20mm gives great results, but the AF is so much quicker and quieter on the 25mm that I think it's worth the extra expense.

    Honestly I wish they'd do a 20mm ver. 2 with the silent focus of the 14mm. Oh and slap in some nano-coating for a boost in contrast and to minimize CA!

    Got the lens. wow, it's quite heavy even compare to m.zuiko 45mm f/1.8 but the focus speed is just lighting fast! Worth the extra cost.

    Focus comparison around 4:20 or so. PL25 is much faster.

    Are you saying the focus speed of Pana 25mm f/1.4 is faster than Oly 45mm /f1.8?

    I mean, the focus speed compare to Pana 20mm. Huge difference. I just wish the weight and size is like oly 45mm.
