These lenses are such good value, but in fact, due to quality issues and their popularity, it would be good to buy several examples from different vendors at different times.

The lovely soft focus ones are ideal for flattering moody portraits esp in low light.

Some of the others would be very interesting if they hit their intended performance limits? Tweaking these lenses might also alter their performance?

Selling on, would be easy with a few examples of that precise lens pics. Keep two or three for your own use.

I agree that most c mount lenses are overpriced. However, that does not mean they will not increase in price!

Y'know... I've had a bit of annoyance regarding the Fujian lenses because new users keep confusing it with the excellent Fujinon-TV c-mount lenses, and the edge softness is so apparent. But the images posted in this thread make me appreciate it as a fun, cheap lens that covers the APS-C sensor.

Out of curiosity, what other c-mount lenses cover the NEX sensor? Do you think, for instance, a Fujinon-TV 35mm/f1.7 model CF35 for 1" video will cover the NEX sensor?

Well, the little brother of the Fujian 1.7/35, the 1.4/25 doesn't. Sad

I wonder if these perform any better on the new Nex, which seems to give better corner performance from wide lenses?

China has, not yet, taken Mt Fuji!

The naming is deliberate, but we lack locus standi to sue for the confusion!

The longer lens certainly has the better performance, but since they both are produced in the thousands still, I have neglected to buy them, despite 'watching' them for years!

The NEX has a good chance of minimal vignetting, but as the admirable Nordentro shows, the lens has good bang per buck, albeit on m4/3.
Even 1/2 inch sensor lenses, 8mm is actually very similar in coverage, will work at 38mm and above, at least for some lenses. I am just buying a D to c mount converter:-

Click here to see on Ebay

I wish to establish this for a navitar and a raptar, both 1.5 inches in FL.

For the NEX, I would say try the Fujian. If it pleases then keep but selling it will be easy, as m4/3 would know and other NEX users might like the effects evident on exemplars posted with the advert?

I am a great advocate of the fact that individual lenses differ greatly in some cases where QC is poor, as in China and DDR and USSR. Some offer clearly superior results even probably as to coverage although a mm is small in m4/3 and even APS sensors that can make a difference! So buy two or three at different times!

Always choose a vendor who has many sales over a newer one even if the newer one is cheaper. Another poster and I were customers of Cowy7 who like too many, absconded with $$$ one Xmas!

Where can these Fujian C-mount lenses be purchased?

I bought mine on Ebay Wink

This lens has very soft edges, but can be useful as a special effect lens wide open. Edge sharpness improves when stopped down.

I just received mine from eBay. The aperture ring is almost stuck, and it won't open all the way to f/1.7 (you can see a hint of the blades). It takes a decent amount of force to close it to f/16, and then it even goes past that! I got mine past f/16 and the blades crushed into each other, not a pretty sight Smile The focus ring is smoother, but nothing as I expected (although it seems to be getting smoother the more I play with it).

Did you find your copies to be similar? I'm particularly worried about the aperture ring...

No. My copy has a smooth focus ring and a very smooth aperture, sometimes even too smooth, so that you change it accidentally.

I contacted the seller and told him about this. He assured me they check their items before sending to avoid these situations, but promptly offered to send me another one, free of charge. He didn't even ask me to send this one back! A little suspicious, if you ask me... Oh, well, these Chinese eBay sellers and their mysterious ways... Rolling Eyes

So now I have a spare 35mm f/1.7 to play with. I suppose I will try to disassemble it and fix it myself. Has anyone tried in the past? I'm not new to disassembling lenses, but by no means good at it Very Happy

Very good, we welcome nice gestures like that Wink
Please document and share pictures and thoughts if you open your lens! Very Happy

I've just bought one of these for the same price. Need to charge up the NEX and go out with it soon but from testing it looks to be sharp in the centre so I don't think I have a terrible one. It's necessary to partially unscrew the lens from the c-mount adapter in order to change the aperture though, possibly due to it being recessed into the camera body slightly.

Dave, you should post some of the shots from your flickr in this thread, the one of the Land Rover is beautiful and the fence shot really shows off the shallow DOF.

Center sharpness of this lens is in general good as mentioned, but you have to stop down hard to get some sharpness out in the corners on a m43 system.

So I guess that U never can get the corners sharp on a Nex with larger sensor than m43.

Thanks Dave. Smile

Nice Dave, I like the color boost Very Happy

Thanks!

I'd like to add that I haven't meddled with the colours more than my usual parameters that I apply to all photos, the lens delivers very good saturation and and it was a very golden sunset!

Those images (fantastic light!) excellently show the way this lens renders. Thanks for that.
