RokinonRK12M-MFT-SIL 12mm F2.0 Ultra Wide Angle Lens for Olympus/Panasonic Micro 4/3 Cameras

I love this lens! I’m a landscape photographer, and this really took my breath away. Really sharp images and quality for the price! It isn’t the best lens out there but for the price you will never hesitate. It’s ideal for traveling since you don’t have to worry about damages, getting lost and focus on photography!

Even though the description says it supports sony e mount cameras, the lens does not fit my a6000. Disappointed as I was looking forward to using it.

Mi primera impresión cuando recibí este lente fue muy buena. Desde el empaque y la caja que corresponden al precio y valor del lente. Incluye una funda de tela relativamente gruesa y un parasol el cual es reversible en el lente para guardarlo, pero de esta forma el estuche queda un poco justo para poder meterlo, pero ya dentro sobra espacio.El lente se siente muy sólido, el aro del diafragma se mueve no tan suavemente pero nada que dificulte hacerlo, haciendo click en cada paso de apertura. EL aro del enfoque está un poco justo y cuesta un poco de trabajo girarlo pero también nada que imposibilite el uso.En cuanto a la montura queda de manera perfecta en mi cámara Fuji X-T2, sin ningún espacio entre el lente y la cámara que permita algún movimiento. La colocación se hace con suavidad y sin ningún esfuerzo distinto al normal de cualquier lente.La calidad de imagen es muy buena, es muy fácil enfocar con este lente utilizando la función de la cámara donde resalta la zona que está enfocada. No entro en detalles técnicos de las imágenes pues, primero, NO he tomado muchas fotos con el lente, y segundo al NO ser yo un fotógrafo profesional no me siento con la autoridad para poder dar un juicio correcto al respecto.El uso de lentes de enfoque manual, en lo personal me gusta mucho para el retrato pues así me concentro en ver bien los detalles de lo que estoy retratando y reviso bien los parámetros. Dicho lo anterior no me molesta mucho que no sea de enfoque automáticoAl ver la calidad del lente mi siguiente compra será el 50mm f 1.2 debido a mi buena experiencia con estos lentes y que no necesito al menos en este momento en gastar en lentes de mayor precio que para mis necesidades NO profesionales me dan los mismos resultados.

For this aperture size for this focal length for this price it is a fairly good deal.That being said there is some chromatic aberration. Purple on the playground sign, green on the light post. The playground sign is about 1/4 of the way into the photo, so that is fairly close to the center. The playground sign only picture is from my 18-55 and it is right on the edge of the picture and has neither.Other than that the lens feels good quality. You can get pretty close and focus short range pretty well. Long range will have everything quickly being in focus, which is kind of nice for night sky pictures. Maximum focus is not bad, but if you turn it just a bit back it will get better focus.A good lens to test if you like that focal range.Edit: added zoomed in pics so you can see the purple and the green.

I’ve had this lens for only a few weeks and I love it. I’ve been doing professional wedding photography for years, and although I haven’t had a chance to use this lens for that, I’ve tried it on portraits (kid and pet) and a little on family photojournalism, and it’s fantastic. I’m used to auto focus, so this takes some getting used to, but it’s becoming one of my favourite lenses to use. Can’t wait to use it in landscape, architecture and wedding photography.Lens feels sturdy. Focus is stiff and consistent. Aperture clicks.

Very sharp, the focus reading are correct, infinity is accurate, very well calibrated for x mount. focusing is relatively tight, feels ok and does not affect use, but nowhere near the feeling of zeiss or voigtlander manual lenses, could be just my copy too. If you need actual full review search online there are plenty.

Knowing that this is not an auto focus lens; this is a great lens. It took awhile for me to get out and use it, work & life gets in the way, but this is quickly becoming my "go to" landscape lens. I use it with am Olympus OM-D-10 Mark ii on a tripod set up. Since its still winter in Canada all of the photos have been winter shots. I am a intermediate shooter and I enjoy using the manual aperture and focus. It is great practice to understand settings, controls and how to focus. I can't wait for some spring & summer night photography outings..
