    "...It's sharp, yet flattering to people. It makes dull pictures look just a bit more interesting, and it makes good pictures look great...." Read more

    "...I've had such a blast shooting with this lens, as it produces some stunning bokeh. It's creamy, it's smooth and it's not distracting...." Read more

    "...2. Bokeh is OK, but could be less hard-edged.Cons:1. AF motor is a bit noisy...." Read more

    "...Image quality is superb, something that virtually all reviewers agree on...." Read more

    68 customers mention65 positive3 negative

    Customers like the lens. They mention it's a great lens for low-light moments, a good first all around street lens for BMPCC, and perfect for their needs. The optics are great, and the autofocus is loud and slow, but it' s focusing well. It's also a fantastic lens for the 4/3 system, and it' is truly a night-vision lens.

    "...out there where you can go crazy, I think this tiny, cheap, and superb lens is more important than ever to the Micro Four Thirds system...." Read more

    "...the autofocus probelms you read online, I'd forget it, it's a great focusing lens especially for its size." Read more

    "...The render is one big reason to buy this lens. Its superb. Excellent contrast, nice color balance and saturation...." Read more

    "...It is an impressive little lens!Pros:1. Tiny! And, light!2...." Read more

    63 customers mention63 positive0 negative

    Customers like the size of the camera lenses. They mention that the build is very sturdy and compact, making it easy to take. The size factor fits the e-PM2 better, and the lens is excellent small. It feels very light and is easy to tote around with a camera strap around their neck. The weight and small size make balancing on Ronin S very easy. The built quality, fit and finish is excellent, and it is a slightly wide-angle lens.

    "...all these other lenses out there where you can go crazy, I think this tiny, cheap, and superb lens is more important than ever to the Micro Four..." Read more

    "...Built quality, fit and finish is excellent. So far it seems impervious to ghosting or flare at any stop...." Read more

    "...It is an impressive little lens!Pros:1. Tiny! And, light!2...." Read more

    "...And it's small and light, so if you can work with the width of the field, this makes for a nice lightweight rig on your 4/3 camera of choice...." Read more

    Customers are satisfied with the sharpness of the lens. They mention that it is super sharp, has nice color, fast focus, and is very light and portable.

    36 customers mention32 positive4 negative

    Customers like the value of the lens. They say it's great for the price, and the price matches the performance. The 12-50 is great, but it' s a little long and awkward to the E-M5 slim. The maximum aperture makes it a very valuable tool for any M4/3 user.

    "...other lenses out there where you can go crazy, I think this tiny, cheap, and superb lens is more important than ever to the Micro Four Thirds system...." Read more

    70 customers mention27 positive43 negative

    Customers are mixed about the focus of the camera lens. Some mention that it has a very good autofocus speed at all apertures, comparable to other high-end lenses. However, others say that it's slow focusing, and sometimes pictures are too out of focus around center if they take pictures at 1.7 aperture.

    "...The only drawback? Slow focusing, again, something everyone comments on. So, if you need immediate focusing, this is not your lens...." Read more

    "...I've consistenly found the 20 1.7 to have very good autofocus speed at all apertures, comparable to my dslr with a similar lens...." Read more

    50 customers mention31 positive19 negative

    Customers are mixed about the speed of the camera lenses. Some mention that it works nicely with their camera and attached flash, while others say that it's slow in low light conditions, the focus ring just feels super slow, and the camera runs out of patience. It's not good when shooting video, and it'd be better to use a different lens.

    "...I've used this lens with on-camera and attached flash, works nicely, AND there is no shadow of the lens caught in the photo...." Read more

    "...version of this lens, and gave it three stars because the AF speed was close to terrible. That was a few years ago...." Read more

    "...I can verify that a step down ring works acceptably well and can even be stacked onto a filter without vignetting...." Read more

    my name’s Chris Winter and today I’m going to take a look at what has become one of my all time favourite lenses, the Panasonic
    Hey what’s up everyone, my name’s Chris Winter and today I’m going to take a look at what has become one of my all time favourite lenses, the Panasonic 20mm 1.7.I've been using this lens for about a year now and have absolutelyy fallen in love with it’s image quality and size.And if you haven’t seen it yet guys, make sure to check out my top 5 best value micro fours thirds lenses list. I’ll put a link in the description box below so go and check it out.Let’s first take a look at the build quality of this lens.When you first pick up the panasonic 20mm 1.7, you’ll definitely notice just how small it is. Even though the lens does have a very wide 1.7 aperture, Panasonic has been able to keep it down to a tiny size.There’s not a whole lot of plastic on this lens either, with a metallic body and metal mount on the rear, it does feel like it’s going to hold up well to years of use.On the front we have a beautiful focus ring which is incredibly smooth to turn. I really love it. There's no image stabilisation on the lens or a manual focus switch, but that's because it's actually got full time manual focus, which is a nice touch.Before I used the 20mm 1.7, my favorite focal lensht was a 50mm on a full frame body. But that's all changed now and it’s now 20mm. That equates to about 40mm on these bodies and it's a great field of view for most shots.Just so you can get an idea of what that focal length is. Here what 20mm looks like. And just for comparison, this is what 12mm looks like on a micro four thirds body and here is what 32mm looks like.So for me, it's a very happy medium at 20.Let's now talk about bokeh, or the background blur behind your subject.Before I found this lens, I never thoguht that you could get such shallow depths of field with a) such a small lens, b) a wide-ish angle of 20mm and c) on a small micro four thirds camera. But as you can see, I was wrong.I've had such a blast shooting with this lens, as it produces some stunning bokeh. It's creamy, it's smooth and it's not distracting.Not only that, even at wide apertures the shots are still tack sharp and you're still getting some lovely bokeh. I've very impressedThe 20mm 1.7 has a minimum focusing distance of around 20cm, which isn't the closest focusing lens you'll find.That's not to say you can't get some nice detailed shots with it, as you can see here, as we zoom in to 100%.But it's definitely not a dedicated macro lens.Now one of the biggest issues people have had with this lens is it's autofocus speed, and you know what, I havent had any issues with it.I've consistenly found the 20 1.7 to have very good autofocus speed at all apertures, comparable to my dslr with a similar lens.The only time I'd ever have any problems withe autofocus is in very low light conditions, and then i'd simply switch to manual focus, no biggie for me.So if you’re worried about all of the autofocus probelms you read online, I'd forget it, it's a great focusing lens especially for its size.
