Panasonic Leica DG Summilux 15mm/ F1.7 ASPH. H-X015 -S (Silver) - International Version (No Warranty)

I purchased this lens, as opposed to the same lens in black mostly because I was in a hurry as I was leaving for a trip where I could really use it. The lens is/was for a Panasonic GX1, so the review is based on the operational combination of the two.I also own the Panasonic 20mm/1.7 and 25mm/1.4. Compared to the 20mm, the autofocus is much, much faster with seemingly less mechanical noise to it. At 1.7, they do seem to have similar ability with light. This is totally different than the 25mm which is much brighter, of course at F1.4, but the autofocus is similarly speedy. I found that the 20mm was really not quite in my sweet spot in terms of field of view -- it was usually not close enough or not far enough, whereas the 15mm and 25mm combined seem to fit the spread a little better. The 15mm is larger than the 20mm, but smaller than the 25mm, so it's a good in-betweener in so far as barrel length goes.The photographic results are a tad better than what I've seen on the 20mm, but the real kicker for me was to have something that was a little wider than the 20mm, so I was happy that the image results are at least on-par, if not better. The "metallic" body is nice. I wanted the "black" version, but it was not in stock when I wanted to order it. I've since grown to like the contrast in color between the lens and camera.The aperture control is physically on the barrel if you want manual control, but the aperture can be also controlled in menu as other lenses. I find that the manual control is a very nice touch. It rotates easily and is "notched" internally to represent those sizes not displayed on the barrel (from 1.7, 1.8, 2, 2.2, etc...). You can "feel" when the aperture ring hits another setting. There is also a switch on the barrel to go between auto focus and manual, which is a nice touch -- but a little small and not quite as easy to operate as I would have hoped. It sticks a little bit.Overall, I think this lens was worth the price I paid. It was a prime purchase at the time so I was able to get speedy delivery. It was far less expensive here than pretty much everywhere else I looked as well -- which helps immensely as I don't think I could quite recommend this lens if it were in the 500 - > 600 dollar range. For that, I give it 5 stars. If it were that expensive, I would give it 4 stars and say that the 25mm would be a better purchase for that price.

Ordered both black and silver versions for my GX8 and GX7 and they work flawlessly. They give very good sharpness, contrast and clarity overall and have better build quality then my Leica 25 & 45. The only downside I have seen so far is a bit high in CA when shooting in the sun! Highly recommended for micro 4/3 users!!

This lens is nice! I LOVE LOVE LOVE LOVE IT! The only reason I’m giving it a four stars is because there seems to be no image stabilization. But I bought it mostly for low light situations where I’m doing a sit down talking clip in my room. But other than that it’s awesome!!!

I decided to "cheap out" and buy this international version, which doesn't have the Warranty and then, of course, shortly after receiving it, I let the lens roll off the bed and smack into my bed frame and dented the lens hood...Thankfully though, Panasonic makes a tough lens and the functionality and sharpness of the lens were unaffected. I've lugged this thing all over the country, took it onto planes, and let it bounce around in my bag while hiking. It can handle all of that and takes great wide-angle images!My M. Zuiko Digital ED 12-40mm f2.8 Pro gets much more use.

Great lens - IQ, size and function (with manual and auto modes on the lens itself and a focus ring). Unfortunately, the piece I received seems to have an issue with Continuous AF, as it constantly hunts and you can hear the motor struggling. So i am relegated to using in the Single SF/ manual mode only.

I'm not a pro-tog. I just travel a lot (different country each month) for work and fun. My use-case is mainly to Instagram and make cool short videos for social sharing with friends. I go out a lot at night, so I also need a good low light lens since I prefer not to use flash.I've included some shots with the lens on an Olympus OMD-EM10 set on iAuto (usually iso200, f1.7) so you can tell what image quality looks like in the hands of an amateur doing normal people things. Evening shots. A food shot. Travel shots with a person far away, medium distance and close up. The most fixing would be me hitting the 'enhance' wand button that standard with Apple OSX or iOS Photos app (too lazy to load up Photoshop nowadays).I also have the Panasonic Leica 25mm/F1.4 lens as well. I absolutely love that lens as well. The 25mm will shoot better portraits and definitely can tell the difference shooting at night with no flash. The 15mm is a bit easier to shoot with traveling around outside, as you don't need to stand as far away at times. It is also a bit smaller and lighter. And the included hood and rubber lens cover really makes taking out and putting away the camera much quicker and convenient (I'm not a very careful person with things). I highly recommend both lens, and it's different enough to warrant getting both (I held off for awhile). But if you had to choose one; then again consider your use case.For non-pros who are use to zooming. This isn't for shooting like that. Trust me, having a fixed prime lens will make you start shooting better and you won't miss the zoom as you have your feet.I will say the quality of build is at least or better than what I expected at that price. It looks and feels nice. Huge difference over the kit lens.

This lens is incredibly well built and is a pleasure to handle. Super sharp wide open and clinically sharp at f2.8. Autofocus is lightening fast, and manual focus is smooth as butter. I stopped using my penny 20mm f1.7 since I got this lens!

Really disappointing compared to the 25 mm Leica. Just wanted a great fixed lens but this one is overpriced for what you are getting.

これで故障していたら、たまったもんじゃあない。まず、梱包が雑すぎる上に、レンズは埃まみれ、カビらしきものも確認できた。どうしても必要なので使うが、正直に説明しておくべき。

同じパンケーキレンズからこちらにしました。焦点距離が短いのでカフェでの写真でめちゃくちゃ役に立ってます。フォーカスもすごい速さですが、ピントがしっかり合わずにゴリゴリゴリゴリ…とチラつくことが多々あります。ただ不自由はないですね。明るいし綺麗だしコスパのいい良いレンズです。

使い易いスペック

まず、箱から取り出した時点でニンマリしてしまいました。小型・軽量でありながら、非常に上質感のある造りだからです。鏡筒は冷んやりとした手触りの金属製で、文字は溝に塗料を流してあるタイプです。LEICA DG SUMMILUX 25mm/F1.4がプラスチック筐体で文字も印刷仕上げだったのと比べると、同じライカ銘のレンズでも、こちらは外装の仕上げにもかなりこだわったことが伝わってきます。さらに、金属製のフードを装着するとき、最後に吸い込まれるようにカチッと固定される感じや、絞りリングのクリック感にも精密に組み上げられたレンズならではの手応えがあります。特筆すべきはマニュアルフォーカスリングのぬるっとした滑らかさです。自分が所有しているマイクロフォーサーズのレンズのなかでは、オリンパスのPROレンズがしっとりと滑らかなフィーリングで好きなんですけれども、それよりもさらに滑らかにぬるっと回転するので、必要もないのにマニュアルフォーカスをしたくなります。肝心の写りについては、言葉で説明するのが非常に難しいのですが、一言でいえば情緒があるといいましょうか、明るいのでボケるとかいう単純な話ではなくて、その場の雰囲気を伝えてくれるような写りをしてくれます。ライカ銘であることによるプラシーボ効果の可能性もありますけど、このレンズの成り立ちを考えると単純にそうとも言い切れない気もします。パナソニックのライカ銘のレンズは、パナソニックが設計・生産を担当していますが、設計図が出来上がるとライカの担当者に見てもらって修正するというプロセスを何度も繰り返し、さらに生産工程でもライカの担当者から色々な指示があるそうです。ライカがドイツで製造している生粋のライカのレンズには敵わないとしても、ライカが培ってきたレンズ設計や生産のノウハウがこの日本製のレンズにも注入されていることは間違いないです。というわけで、カメラや写真が趣味で、こういった「造りの良さ」や「写りの良さ」が理解できる人にとっては、このレンズの価格は決して高くないと思います。手元にあれば所有する喜びや、写真を撮る楽しさを存分に感じさせてくれる優れたレンズです。お財布に少し余裕がある人には、ぜひおすすめしたいです。

GM1に、20mm/F1.7をつけっぱなしにして、主に子供（9歳と5歳）の撮影をしていたのですが、不満点が２つ。①室内で、画角が少しだけ狭い②AFが遅い（とくに連写・動画）そこでいろいろ情報収集した結果、こちらの商品で両方クリアになりそうと思い、購入。結論、両方クリアになりました。とくに飲食店の4人席で向かい合っている2人が、20mm/F1.7だとぎりぎりはみ出てしまうのが、きちんと収まる！連写しても動画を撮っても、AFはドンピシャ！たまに背景にピントが合ってしまう時もあって気になりますが、それは多分レンズではなくカメラ側の問題（顔認識の精度？）かと思っています。僕に限らず、20mm/F1.7の課題を、こちらの商品でクリアにしてる方は多いようですね。同じ状況で迷っている方は、いっちゃいましょう！！あと、僕は他の一眼レフ（安いやつですが）も2台持っているのですが、GM1に15mm/F1.7をつけっぱなしで、首からさげっぱなしスタイルにしてから、他のカメラは一切使わなくなりました。首からカメラを下げて少しでも重いと肩がこるし邪魔、だからってカバンにいれるといれたり出したりがめんどうで撮影枚数が減って、あまり撮らないからまぁいいかとだんだん持ち歩かなくなってしまっていました、、、それに比べるとGM1＋15mm/F1.7は首からずっとさげていても、さげているのを完全に忘れる軽さ！です。このスタイルにしてから、撮影枚数が何倍にも増えました。いつでもサッと撮れる、一切めんどくさいない！その写真をiPhoneにWi-Fiでとばして、LINEでおじいちゃんおばあちゃんにシェア！　これで親孝行も完璧です。正直、15mm/F1.7のためにGX7MK2Kも欲しくて量販店に行くといつも手にとってみるのですが、この重さだとギリギリ、首からさげっぱなしにしなくなるだろうなと思って、購入を諦めてます（笑）とにかく首からさげっぱなしにしても、さげてるのを忘れる軽さ、それが一番大事だと思っていますが、このレンズは、そのあたりはバッチリです！
