Review on Rokinon CV14M NEX Clicked Compatibility Wide Angle by Yalena Torres

I am very happy with this lens! I currently have several Rokinon/Samyang lenses. You are of great value. This 14mm is my second. The first was a photo version, and there was a bug in it. It focused on a significant backlash. So I sent it back (from another mail order company) and got the film version here on Revain. It doesn't have any problems, except that finding the perfect point of focus can be a bit tricky. However, the final image is very sharp. These extremely short lenses tend to be more difficult to focus due to their large depth of field, unlike long lenses with a shallow depth of field, where you immediately realize you're not perfectly focused. On the other hand, a large depth of field makes it easier to control - most of the time I just estimate the distance and stop. This enables very quick action and certainly makes autofocus superfluous in this wide-angle range. However, it seems that Samyang - the maker of Rokinon - has some consistency issues with the tolerance values. Note that the shorter the focal length, the tighter the tolerances required. If you compare how much the lens moves between a short WA and a telephoto, you'll find that the WA makes very little movement when focusing, unlike a telephoto. That's why they need a lot more precision. Also, they usually have a lot more lens elements and they all have to be in perfect position or something will show up in the image quality. That's why you pay so much more for Zeiss, because they're just better at keeping tolerances tight. So if you come across a defective item, simply return it and order another same item. Most likely, the problem has disappeared. If you can test the lens before you buy it, that's even better. I use my Rokinons on a Sony full frame and an APS-C sensor. And I choose them all A-mount, although I have E-mount cameras, so I can also use an adapter to shorten the focal length and have a full wide-angle lens on the crop sensor - basically that gives me 2 focal length options my a6000 - plus light amplification! And with my full-frame 36MP capture, I only crop what I don't want and still get the same MP quality as APS-C (24MP). A common problem with adapters is that the infinity focus point is too far away. This can be adjusted by unscrewing the bayonet plate on the lens side of the adapter and placing thin sheets of cardboard or paper between them, screwing it back in and cutting the extrusion of the material in and out. Through trial and error, you can bring the infinity point to the end of the focus ring, achieving the same distance scale and scaling. Just don't over-tighten the tiny screws, and gradually tighten them alternately so they're all tightened the same way - otherwise you could experience a tipping effect. If this doesn't happen, it's worth scratching the mark on the infinity scale to find the infinity point without focusing (helps a lot in the dark!). Try to keep the lines straight, stretch the image towards the outer areas. That is his nature. In architecture this is usually necessary to keep lines straight. This is not noticeable in the landscape. You can avoid this stretching only with the help of "fish eye" - it doesn't stretch the lines, but curves them. Even in a landscape, this isn't a problem as long as straight lines (like the horizon) stay in the center of the image. I also recently bought a Rokinon 2.8/12mm full frame fisheye lens. It beats all my other lenses out of the park as it's a sharp-ass go-getter! It has a little chromatic aberration (which can be corrected fairly well in post-processing), but it's very sharp. A real alternative to 14mm is when the curved field isn't as important (as with landscapes and other non-straight subjects). And if you "unfish" it in the post, the lines can still be straightened with relatively little yield loss, and even then it gets significantly wider than 14mm. It has now become my go-to ultra-wide lens. And again, using it on either my full frame A7R or APS-C with or without a gear adapter makes it very versatile at very high quality. And last but not least, both lenses shine with excellent anti-reflective coatings, stray light to an absolute minimum. This is important for ultra-wide cameras, as bright light sources are almost always captured in the frame. And at maximum aperture, beautiful, even star-shaped rays emerge around them. Both lenses are fantastic - it all depends on what you need them for. Enjoy and create!
