Sigma 30Mm F 1.4

[58 mm (Front)] I bought this along with the Sigma dc dn art 30mm 1.4 for my a6300. Optics wise I would choose this over the Sigma. The Rokinon is heavier with a plastic body and yet still nice feeling .There is little purple fringing wide open on high contrast scenes and it is completely gone between f2-2.8. The sharpness and contrast throughout is fantastic. I was surprised how well it did at 1.2. There is no noticeable distortion. The colors are great. The bokeh is very smooth. One of my favorite lenses I have ever owned. I plan I using this for Product shots, video and portraits. Remember if you buy this it is for apsc not full frame. Also manual focus only, which is very smooth. I would 100% recommend this lens. I posted a photo I took with it!!!

[67 mm] I used it to step-down my my sigma 30mm f/1.4 lens in a sunny day. It works well. But according to the camera reading, it only does 2 1/2 stops.

[0.09 lb] OEM replacement for lost lens cap for Sigma 30mm f/1.4 Sony e-mount prime lens. �Fits perfectly at a reasonable price.

[Yes] 30mm is my favorite walk-around lens for MFT. I like a little compression, especially for portraits. I agonized over the Panasonic 30 2.8 micro and the new Sigma 30mm 1.4 lens. I ordered the Sigma lens but returned it after a few test shots; too many artifacts and purple fringing. The Panasonic lens passed testing with crystal clear shots (yes, I am a pixel peeper at 14x). Losing two f/stops doesn't bother me, especially given the multi-stop stabilization in today's MFT cameras/lenses. At 5 feet (portrait range), the depth of field at f/1.4 is only 3.5; one often has to choose between having an eye or an ear in focus but not both. At f/2.8, the depth of field is 8.5 ... good enough to have the head in focus with a pleasant bokeh in the background. The fact that the Panasonic lens is a macro lens has the advantage (characteristic of macros) of having a flat field in crystal-clear focus from f/2.8 to f/8, after which diffraction starts. I may never use the Panasonic macro capability, but it is there if I need it.

[66 to 68 mm] Works on Sigma 30mm f1.4 for Sony E

[0.085 lb] Bought a purple one for my Sigma 105mm f/1.4 and it’s perfect.

[Pentax K] Very pleased from this lens. very sharp, light, and with no distortion, unlike of most mirrorlens lens. i had the Sigma 30mm f1.4 for my Sony a6300, and this manual lens is much better with no distortion, unlike tge sigma 30mm f1.4. the price, the quality, the lightness, all of this makes it a great lens.

[0.045 lb] It's the OEM lens hood to go with my Sigma 19mm and 30mm f/2.8 DN Art lenses. Fits perfectly and does what a hood needs to do. Haven't really tested the optical effects of the hood because I mostly bought it for protection of the front element

[FUJIFILM X] Quiet, Small, and light. This lens gives me just a little more of a wider picture them the 30mm by sigma. and is just as sharp and is nice & quiet also.

[Zipper] Came with a Sigma 30mm f/2.8 but I have purchased three more for my other sony e-mount pancake and compact lenses. They are well padded for storage and transport, but have no connection points for straps or belts so keep that in mind.
