Panasonic LUMIX H-RS100400E 100-400 mm LEICA DG Vario-Elmar Lens - Black

This lens bears the Leica label and because of this I tend to assume the quality of the image is optimal. In initial use I am happy with the results. The build seems solid and useful tripod mounts are provided although with the image stabilisation good results can be achieved at extreme range when handheld. I am very happy with this lens.

This lens is excellent. There are lab reports and professional reviews on the net that tell you that. I had 2 concerns from other reviews that proved groundless. On my Panasonic camera it focuses very well. The other concern was stiffness of zoom function. At first I thought this was true until I realised it is supplied with the zoom lock on. It is a brake rather than a lock and makes it very stiff, fine when you release it. One further benefit I found which exceeded my expectation was the manual zoom. When you select it the lens zooms in very close to let you focus precisely and zooms out for the shot when the shutter is partially depressed. Clearly this lens is a significant investment, but it does at least what I expected and a bit more.

Very sharp lens, with excellent zoom range, just a little soft at 400mm. Easy to hand hold with GH5 at slow shutter speeds.

Had been coveting for some time, then a decent used one came up at a sweet price. Seems a massive upgrade on our previous longest zoom of 45-200mm, very rewarding sharpness right to the 400mm end (rumours to the contrary seem unfounded at least on this copy), acceptable focus speed, great stabilisation and beautifully rich colours. Build is exemplary, and although the metal construction is heavy it seems well balanced, and there are tripod options should one need. The zoom isn't excessively stiff but enough so to prevent creep (which would easily be an issue given the weight of the lens) and there's a lock too, just in case. The hybrid lens hood arrangement is a bit awkward (and the tightening screw proven vulnerable), but it's certainly flexible and I'm sure I'll get used to it. I sense I'm going to enjoy using this lens a lot, though with it's minimum focal length of 100mm I will still be needing shorter lenses in my camera bag!

Stunning lens. Not just as it let's me get up close. Getting amazing results. At 300mm pictures clearly better than the 100-300. Slightly soft at 400 but pin sharp at 380 or less. A great lens, heavy for mft but so much lighter and smaller than a full frame equivalent. Love it.

Have had this now for a few weeks and I must say that it lives up to its Leica heritage both in construction and the optical quality of its glass. I use it on a Panasonic GX8 and the results are amazing. The photos were all handheld at 400mm and tweaked in photoshop. You know you want it. If you can afford it you wont regret buying it. I took this lens when I spent a month in China Oct/Nov and was well pleased with the results. I have downloaded a couple more images.

A fantastic purchase! Used with Panasonic GH5 to produce fantastic telephoto images in sharp detail with brilliant stabilisation. A great addition to my camera gear. Fully recommend if you want a telephone lens.

Feels well made with Leica optics. not tried low light shots yet so left that blank, but I am sure it will be fine.

If you are familiar with the Micro Four Thirds platform, you will know that this lens gives you a reach of 800mm (full-frame equivalent), yet in a relatively small package in terms of both weight and price. Lens is pretty much sharp throughout and fast enough given Dual IS mode on my Lumix G9. The lens that I received was made in Japan and arrived promptly. Am very happy with this purchase.

I risultati sono incredibili e magnifici se sai regolarla bene, ma l'uso è complesso e di certo non adatto ai principianti. La ghiera dello zoom è molto dura da ruotare ne risulta che muovendola durante un video la zoomata può risultare scattosa e a mio avviso è il difetto peggiore.

Pesa poco, es rápido, también se le ve una buena construcción, la estabilización va muy bien, lo utilizo para naturaleza, sobre todo aves, pero también para comprimir paisajes, lo utilizo con una Panasonic Gh5s y sincronizan muy bien.

Dieses Objektiv bewährt sich bei mir derzeit fast täglich in der Naturfotografie. Ich bin mittelmäßig erfahren, doch die ausnehmend wirksame duale Stabilisation mit Objektiv und Body der Lumix GX9 ermöglichte mir schon herrliche Aufnahmen aus freier Hand. Ich fahre mit dem Rad durchs Moor, sehe ein Reh, einen Hasen, einen Kranich und binnen Sekunden ist die Kamera einsatzbereit. Nach meiner Erfahrung ist der Autofokus bei höchster Brennweite zwar sehr schnell, doch man kann als Anfänger auch schon mal leicht daneben hauen, weil die Schärfenebene in diesem Maßstab etwas kritisch ist. Daher habe ich mir für Tiere in Feld oder Dickicht den manuellen Fokus angewöhnt, der mit der blauen Peakanzeige intuitiv bedienbar ist und auch unter Stress gut kontrollierbare Resultate liefert. Die Bilder sind nach meinem Eindruck so scharf und kontrastreich, dass sich durch Herausvergrössern spektakuläre Nahaufnahmen erzielen lassen. Vorher nutzte ich das ältere, durchaus brauchbare 100-300mm Zoom, doch dieses Objektiv ist für mich ein großer Schritt nach vorn.

Cet objectif est très performant et rend des photos magnifiques, vous pouvez prendre des sujets assez éloignés, faire de belles photos de nature, événements sportifs. Le stabilisateur est très performant, même en grossissement maximal ça ne bouge pas beaucoup. Seul petit bémol, pour avoir marché une vingtaine de kilomètres avec l’appareil autour du coup, il est peut-être un peu lourd, mais sinon rien à dire.
