Top Customer Reviews
Initial reviews implied that, well, they *didn't* improve on it. This refresh was cosmetic, and the lens was identical optically. I decided to take a pass.
That was, of course, until my E-PM1 (with the original lens attached) went for an unexpected journey on the roof of my car. Suffice it to say it ended well for neither camera nor lens, and when I went to replace the 20mm I discovered that the new version was cheaper than the old. An easy enough decision!
What follows is by and large my original review. Really, the only things that have changed are appearance and the weight, and those only in vanishingly small ways. The lenses are otherwise, as near as I can tell, functionally identical. I've tested this lens on a GF3 and on the E-M5.
First off, this lens really is wonderfully compact - it's physically a perfect match for small bodies. There are smaller pancake lenses of similar focal lengths (the Panasonic Lumix 14mm f/2.5 and the Olympus 17mm f/2.8), but neither are as bright; I think the 20mm hits the sweet spot. The lens has a massive manual focus ring (which is a control for the M43 "focus by wire" electronic focusing system) which is easy enough to use once you get the hang of it.
The updated version now ships with smaller lens caps. It's otherwise basically the same size as the original.
As for the results... well, you can read the charts, but suffice it to say that this is a very good performer. It's sharp wide open, with some very slight softness towards the corners which can be improved by stopping down.
The lens does rely on software correction to deal with some fairly strong light falloff towards the corners at wide apertures. If you don't want to use software correction, note that the vignetting can be resolved by stopping down to around f/4.
Autofocus is as accurate as any other lens I've tried, and low light AF hit ratio is good (thanks, no doubt, to the large aperture). AF speed is adequate but not exceptional, and it's a bit louder than would be ideal for video if you intend to use the internal mic.
Oh, and don't be scared off by the "odd" 40mm equivalent focal length. If you're used to 50mm as "normal" from the film era, I think you'll find 20mm quite pleasant. The little extra width can be nice to have at times.
No discussion of this lens would be complete without mentioning its larger, brighter cousin, the Panasonic Micro 4/3 25mm f/1.4. I own both lenses, and the 25mm f/1.4 is arguably better in several respects; in addition to its faster aperture, the 25mm boasts improved autofocus performance, which is somewhat quieter and faster than the 20mm (primarily when "hunting," which is when the 20mm slows down). The minor aperture advantage of the 25mm is on its own not very significant, but the combination with a longer focal length does provide it with a noticeably narrower perceived depth of field.
So why, then, would I go back and buy the "worse" 20mm all over again? It comes down to size. While the 25mm f/1.4 is great, it's also twice as big, which is why I consider the 20mm f/1.7 a must have for use on smaller bodies (which might be placed in a jacket pocket or purse). It strikes the perfect balance between brightness and size when paired with a "rangefinder" style body (e.g. the Panasonic GM1, Olympus E-PM2, etc). It's a great all around performer and the cost, although high, is not totally unreasonable for something of this quality.
Bottom line: this is a must own for anybody with a small M43 body. And if you find yourself torn between the "new" and "old" versions, or contemplating an upgrade? There's really basically no difference of note. Stick with what's cheaper (or what you already have!)
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 impressed
The 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.
