For $60? Come on, this thing is awesome. Solid metal construction, zero complaints there. Focus ring throw is 1/4 turn of the whole lens, so it's easy to whip focus around if you need to, but realistically you'll be at the "∞" setting all the time. Being fixed at F6.3 means that, at the infinity setting, anything from about 2 ft away to infinity will be in focus. So you won't likely touch the focus ring much / ever.Essentially, this lens is a point-and-shoot dream. Never have to touch focus, not wasting battery on AF motors, no choices to make. Just turn on the camera and fire the shutter! Extremely easy. 18mm is a nice choice, too. Plenty of room to capture your scene.Before IQ, I can't stress enough how _small_ this lens is. It's a brilliant fit on my X-Pro3, with the front edge of the lens just a couple millimeters further out from the built-in grip! I have several XF lenses and nothing comes close to making the X-Pro3 feel like a true rangefinder than this one. It's actually even smaller (thinner) than my X100V. Neat! Carry this thing anywhere.Okay, image quality. This is not a clinical, sharp, corporate-headshots / product-images type lens. It's $60. Go get your $2k G-master for that. What this lens is, is a very filmic piece of glass. Does it have some vignetting on the edges? Yep. Is it slow? Yep — F6.3, especially indoors, means high ISO. Does is somehow blend with the X-Trans IV's high-ISO grain (and/or JPG grain settings) to give you brilliant film-y images with BEAUTIFUL film grain? Absolutely. No idea how it does this, but it just does. The photos I shoot through this lens (particularly with Classic Neg or Acros) look more filmic than pretty much any other lens I shoot.Would I try this lens on the X-Trans V 40MP sensors? Probably not. Would I try it on the older sensors? Absolutely. What this lens doesn't have in resolution resolving power it totally makes up for in character and filmy style. That pairs great with the 26MP X-Trans VI and I can only imagine even more-so on the older sensors.For $60 and Amazon's return policy... give this thing a try. It's great. It'll take you to a simplistic place with your photography that's just "frame and shoot".

Se dispara fácilmente la ISO. Cuidado.

Ürünü çok beğendim. Sony nex ve diğer aynasız cihazlarda kullanıyorum. Bilhassa sonsuz işaretinde mükemmel neticeler aldım. Tavsiye ederim. Sony aynasız cihazları kullananların vazgeçemiyeceği bir lens..

Bonjour à tous,Comme beaucoup le disent, si vous cherchez un objectif qui donnent des résultats ultras nets et détaillés, cet objectif n'est pas pour vous.Malgré tout, il est assez net, mais manque un peu de contraste. Je trouve qu'il est plus net en vue rapprochée que sur l'infini. Mais le gros avantage, (par rapport aux Olympus 9 et 15 mm) c'est qu'il y a une vraie bague de mise au point ultra fluide très pratique pour faire le point. Une précision : quand on règle sur l'infini, ne pas aller jusqu'au bout, mais rester juste 1 millimètre environ avant, pour une netteté optimale.Il est très bien construit, tout en métal. Pas de couvercle capuchon de protection.Il est très sensible au flare, au reflet des lumières fortes. Pour moi ça peut être une qualité parce qu'il permet de créer des atmosphères un peu irréelles que j'aime beaucoup. (voir la première photo) J'aime les photos super nettes et détaillées, mais là on est plus dans le créatif, dans une recherche d'ambiances particulières, cet objectif s'y prête bien. (seule la dernière photo est optimisée)J'aimerais bien le même en 28 mm parce qu'en 4/3, le 18 équivaut à 36 mm...Et surtout il est tellement léger et discret, c'est vraiment un plaisir de l'utiliser. Et pour le prix, franchement...

Per micro 4/3 perfetto!!! Per chi affida l'arte della fotografia mezzi ultra tecnologici...un pessimo affare...ma va bene così!
