    Much of the performance of this lens is exemplary, especially considering the modest cost. The only real drawback is the susceptibility to flare, which is very evident in shots taken into the light. If this can be accepted then the lens is without doubt an excellent proposition.

    The Panasonic Lumix G 25mm f/1.7 ASPH is a very good standard lens at a very affordable price, making it a must-have purchase if you don't already have a 50mm equivalent lens in your kit-bag.

    The 25mm f/1.7 is a solid lens. It’s rather sharp and has good bokeh in most situations. Chromatic aberration is well controlled and color and contrast are quite nice. Focus is also exceptionally fast and relatively quiet.

    For conclusion, I think Panasonic made really good lens. There is not a single aspect where it performs less than expected; at this price point it deserves recommendation.

    If you have a standard zoom or especially a super zoom, it's hard to think of a more useful second lens than this, and as the 25mm component of a classic wide-angle, standard, short tele prime set, it is a shrewd choice.

    I don't know man, to me what I was looking for in my newb days was something like the Panasonic Lumix G 25mm f/1.7 ASPH that we've been talking about in this video, something that's basically the same price but much more useful in my opinion.

    Hope you learned something about it, and my main point with this video, I want you to realize you don't need to spend $1,200 on a lens to get great images.
