Pixco 25mm F1.4 CCTV Lens for C Mount Camera + 16mm C Mount Film Lens to Micro Four Thirds 4/3 Camera Lens Adapter

Overall I am pleased and would recommend this lens.I put this lens on my Sony A7iii, Canon 80d, and Panasonic GH4.The image circle this 25mm lens produces will fit a M43 sensor without vignetting.Some dark vignetting on APSC, and you can see the entire image circle in blackness on Full Frame.I like the creative look on FF. Very interesting to play with.The one big negative imo is that the focus ring is on the back of the lens, where as on most lenses it is on the front. This makes it unpleasant, but not too difficult, to focus as the ring is literally right up against the camera body.Not a huge deal tho considering.Excellent sharpness.Impressively mild Chromatic AbberationAccurate color rendition, not too warm or cold.Good Smooth BokehOut of focus regions do not appear too busy imo.No intense onion rings, pretty smooth. Impressive for so cheap.When stopped down bokeh takes on a pentagon shape.It has a non linear focal plane. (idk if that's the proper term.)The focal plane is spherical so the center will be in focus and the edges will be out of focus, and vice versa.Certainly helps with subject separation if subject is in center.Cool mild swirly effect when subject is center frame and in focus.The out of focus regions around the subject have this mild swirly effect. Very cool. To be honest I wish it were more pronounced.

Plenty sharp in the center, and looks sharper because of the very subtle vignetting. A joy for portraits and such in Micro 4/3, and an incredible bargain. One thing: When you unpack it, you WILL unscrew the front half of the lens when you try to take off the lens cap. As long as you have that half in your hands, just work the rubber cap off -- it's pretty tight -- and then just screw the front half back onto the lens. I saw a caution about this somewhere on the net, and it's true; but no harm done. I would recommend this to anybody for portraiture.

the lens looks well made, unfortunately it did not come with the mft adapter as stated in the listing and is totally useless to me without it.

I am loving the photos iut of this lense! I'm using it on my Panasonic g7 and for the most part it works perfectly.Good:Inexpensive! Its by far the cheapest route for a 50mm equivalent.Depth of field. So shallow and beautiful!Weight, tiny! Fits in my pocket even!The focus and aperature rings work great though they took some time to get used too.Bad:The aperature has markers for the f-stop, but nothing to point at it...Chromatic aberration. Happens with a high f-stop.Artifacting in bright light, no hood.The feild of view is curved. So at f 1.4 the flame of focus is curved and you really have to play with the focus ring to pull focus correctly.All in all definately worth the price, not a professional alternative, but definately a good buy, and great for taking unique semiprofessional immages.

good quality.lovely dreamy optical effect.

People who spend $25 on a lens and expect anything super sharp and detailed and smooth are dumb. I bought this because I wanted a nice bokeh, and a nice bokeh is what I got. The focus ring is surprisingly smooth, the lens is made of metal, and it works just fine. The image gets blurry on the sides, which is just fun, I don't expect to use this for anything except artsy shots and portraits.I made videos, and this is just fine for that.

Full open aperture does not focus the whole frame.

This lens has tendency to fall apart into two pieces - one half will have the aperture blades, the other the outside lens (can think of the two halves as stuffing smaller cup into larger cup).A headache to keep them together (even though easy to put back together) if you don’t have a dedicated place for them.Have to worry a lot more about dust and damage to Aperture blades if anything gets caught inside.As a result it’s very gimmicky and finicky and in my opinion the price doesn’t make up for those headaches as those are the last things you should have to worry about while preparing/shooting etc.If you’re really on a tight budget it’s worth a try but then you also have to adjust your in camera settings as the image on its own usually has vignetting and most people have to use in camera zoom/magnification of some sort to get it out of the way. As a result of having to zoom you do lose picture/video quality not that the quality is that great to begin with (center is usually focused fine but gets less clear towards borders of picture - plus the vignetting...)
