It's interesting how this little lens does such a great job. I'm very surprised. Great for portraits. Maybe not so much for landscapes because of the off doughnut shaped focusing (at least on my copy), but I like it none the less. Cheers.
I have the F1.4 version of this 25mm CCTV lens with a C Mount, that wont attach to Canon 60D, which is cropped, but I guess an APS-C mirrorless like Canon M, M2, M3 would be perfect, but, you talked about adapting to Full frame, does it mean I can find adapters for full frame and 60D? That would save me the trouble of buying the M2 for example. Also, is there a speed adapter that enlarges the 25mm image from this lens to fit the larger sensor, if we dont want to zoom in, inside the camera settings?
I think you brought a lot more with your skill than what the lens is capable of for an average user. But great job and yes, no one can go wrong with a $20-40 lens.
On an aps-c sensor camera, are we getting exactly 35mm and f1.7, or is there any math involved. It seems like it would behave like a native aps-c lens.
From what I've been reading you'll always have to multiply your crop factor depending on what aps-c camera you have to the focal length of any lens. Canon APS-C, 1.6 x 35mm = 56mm.
@@thealaris It doesn't matter if it's full frame glass or crop sensor glass, focal length is always measured the same. "How Full Frame and Crop Sensors Affect Focal Lengths. Focal lengths of lenses are based on the 35mm standard. This means that a 200mm lens on a full frame camera will produce a 200mm image. However, crops sensors have what is called a “crop factor” that helps determine the effective focal length of a lens." So your focal lengths on lenses are always based off of a full frame 35mm standard. And Canon's crop factor for APSC is 1.6x. Here's a video talking about it ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-U-b69rvK5ME.htmlsi=X7nBzDDGAfQ-bBBT .
@@fuzywazacolin2392 Your words literally contradict each other, at first you write that it doesn't matter if ff or cropped glass is used, but than you're writing about crop factor of ff glass on crop sensor. And I've already had written that in previous comment, cause you don't need to multiple focal length of lens if it's made specifically for crop factor that you're using.
@@thealaris There was no contradiction. What you said was that since it is an APSC lens, then they would NOT have to do any math to figure out what equivalent focal length that would be represented on their camera. If you have an APSC camera, you have to do the conversion regardless, whether it's a Full Frame lens or APSC lens. A 100mm FF lens will look exactly the same as a 100mm APSC lens on an APSC camera. If it's a canon APSC sensor, it would be 100mm x 1.6 = 160mm, if it's the rest of the cameras like a Nikon APSC sensor, then it would be 100mm x 1.5 = 150mm. The focal length numbers written on lenses are basically saying "if you could mount this lens (whether it be FF, APSC, or M4/3 lens) on a full frame camera, this is what focal length would Truly be represented, any sensor smaller than full frame would display a zoomed in picture, including lenses specifically made for that sensor size. That's why a lot of M4/3 lenses have such small focal lengths because you have to multiply by 2, e.g 8mm x 2 = 16mm. Just Google "Do I have to multiply crop factor when using APSC lens on crop body?" and you'll find more of what I'm saying. Also, if you haven't checked out the video I linked, check it out.
Thanks, man, excellent review. Since the lens is only $25, it's great for hiking: The spacers are great for macros... the bokeh is unreal, thanks in no small part to the number of blades. And the blurring on the periphery is kinda cool. I can barely wait to play with this lens.
Robert, while I do understand the pricepoint of these, is it just me or is the fact that the center is sharp and the sides are not sharp at all... is that not a deal breaker? Why would you want to use something like this for non-portrait uses?
Hi Bhagwan. That’s a great question. I think the appeal for me is that if is a fun lens to use. It’s extremely sharp when in focus, and the out of focus areas look lovely to me. The lens definitely has its own characteristics that you can’t get with any other kind of lens. I have never used this lens for paid photography, but it could be used for that if someone was on a really tight budget. It would require more work in post, but the portraits I’ve taken with it are nice. It has a 1980s feel to it. I would say that’s the biggest reason. Fun, small, sharp, and interesting bokeh. Cheers.
Hey! I know you’ve probably answered a lot of Questions but I’d like to know if this lenses is compatible with Sony NEX F3? I can’t find any information on this specific camera
Yes. The F3 uses Sony’s E Mount. The lens will fit with the correct e-Mount adapter. It comes with the lens. Just buy the right one. It’s the e Mount /NEX Mount listing.
Holy Crap. VIRGINIA BEACH! That feeling when you're 15 videos deep into your Random RU-vid Video K-hole and realize this was probably being filmed right around the corner from you.
Great video. I received mine copy yesterday, and am doing research about how to use it. For some reason, I have not been ale to manipulate the aperture or obtain a focus further than a few inches from the lens. As of right now, it is a beautiful macro lens. This video encourages me to keep playing with it.
@@RobertHamm It's the same. The only difference is mine has a detachable C to EF adapter. Thanks for the reply www.ebay.com/itm/Fujian-35mm-f1-7-C-mount-CCTV-Lens-for-N1-FX-NEX-Micro-4-3-EOS-Pentax/263218535436?hash=item3d490c1c0c:g:DgIAAOSwkSxbKNV3
Yeah, it looks the same as mine. The only thing I can think of is that the adapter is too large, making the distance of the focal plane longer than it needs to be, which is why you would be able to get those macro style shots with it without using an extension tube. Pick up another adapter and see if that helps out.
this is an old comment, but I just got the 50mm Fujian model and have the same problem with a canon 600D and EOS mount, even if I removethe mount and try to stick it as close as possible to the sensor with my hand I still don't have a decent focus past a few inches away...anyone figured it out?? is it just faulty?
Thanks for this video. I ended up ordering 2 of these for both my camera rigs. It was also nice to see examples from somewhere familiar. I live at London Bridge, and used to date “Ocean” Eddie’s daughter.
The image area is 62mm x 99mm, so it has similar dimensions to 6x9cm roll film. Obviously you can’t enlarge the image like you could with traditional film, but the crop factor is about .63x. So if you were to convert the 93mm lens to 35/135mm it would be similar to a 55mm lens. So if you treat it like a 50mm lens, you’ll be good to go.
@@RobertHamm thanks for tha video, but the main thing is interesting: what view angle this lens look like when using with APS-C? not full frame. Please say it like - "wide as native 50mm APS-C lens (canon ef-s, or fuji XF..)". Thank you
I have one and I use it on my Olympus m4/3 camera. It actually looks very good when compared against my Olympus 45mm f/1.8 lens. I did have to "shim" it a bit so that the lettering on the lens would be "up" and it would not focus past infinity.
I’ve got a canon 5d mark ii . This lens and the correct c mount adapter but everything comes out as blurry , its unusable , could anyone help? Thanks! P.s. nice video :)
The adapter may not be the correct dimensions even though it fits. Could also be the focus ring. Maybe a bad copy. Test it in another camera if you can.
c mount has a very short flange distance, it will only work (barely) with mirrorless cameras. on DSLRs you can only focus very close macro shots, if at all.
Well, I see you’ve still figured out how to be a pensive twit, but hey, to each their own. You forgot a hyphen in f-stop, but I’m sure you figured that out already.
