Sony NEX + Sony Fisheye Converter: Cost $125.00 USD
Posted: 9 Apr 2011 at 9:26 GMT
So, as I mentioned in another thread. I thought it might be worth testing out the Sony NEX VCL-ECF1 Fisheye Converter. This converter lens attaches to the front of the Sony 16mm f/2.8 Pancake lens. As I can never sit still and wonder I parted with some cash and waited for the converter to arrive from the USA.

This converter lens cost me $125.00 USD from an ebay store seller brand new + freight charges.

You will see them advertised as a 15mm (35mm equivalent) lens at 0.62x. This is simply not true. My tests show it to be 0.64x and 10.23mm (35mm equivalent).

With a HFOV of 89.56 degrees

To say I was surprised with the quality was an understatement. Yes, it is soft in the corners and it does suffer from vignetting and chromatic aberration. But these can be corrected with a quality RAW converter. It easily exceeds any converter lens I have ever used by a country mile and really should never be mentioned in the same breath as a Nikon FC-E8 or FC-E9. Chalk and Cheese!

The build quality and feel of the converter lens is of a high standard. It responds well as you would expect as the 16mm f/2.8 Pancake lens it attaches to is a quality piece of glass. It looks correct and stylish when fitted.

The shooting is the same as say the Nikkor 10.5mm Fisheye
Being 6x rotational images at -10 degrees and 1x Zenith shot at +70 degrees.

A great lightweight travelers set up.

Worth the test? You tell me ...

Hmm, thinking about the multiplying factor again.

16mm Pancake x 1.538 = 24.608mm (35mm equivalent)
24.608mm 0.62x Converter = 15.25696mm (35mm equivalent)

16mm Pancake 0.62x Converter = 9.92mm x 1.538 = 15.25696mm

So I guess that is correct.

16mm Pancake 0.64x Converter = 10.24mm was my thinking.

That's impressive. I usually can see softness in the seams but not so much in your example. 8 around would not be much more trouble than 6 and that would eliminate any possible softness at the edges.

I wonder if you can post a link to a raw image that has been converted but not corrected for CA?

The NEX 3/5 looks like a real good choice for panos on the go.

What's the remote look like?

Very nice! I love how you have an Omnipix trash can too. By the way, go ahead and right click. You have an extra "h" and a lack of a "g" in your context menu.

Yes, you could shoot more but you can get away with 6.

Sure, here is a .dng because you will be too limited with a Sony .arw www.omnipix.net/temp/nex/converter/DSC00380.dng

I haven't seen better for size and quality.

Err, the Sony is Inferred only sad But you can add a gentLED as Andrew recommended and trigger with any switch manual or RF with a 2.5mm stereo plug. I purchased one and it works fine. www.gentles.ltd.uk/gentled/trigger.htm

Well, that's just embarrassing! blush Fingers didn't do what the brain said (nothing new there!). All fixed now, thanks for spotting that and pointing it out.

I used UFRaw to convert and view. Probably not the best raw converter. But still, the CA looks very mild. And the various color planes look sharp confused

Way better than other converters I've seen -- you are right about that.

What's the thread size? Did you try it on your LX3?

Just check it's not "pre-reading" my ACR embedded settings. I forgot the .xmp is saved/embedded to the .dng file.

It doesn't have a thread. It clips to the 16mm E Mount Pancake Lens (twist and click). No chance to fit it to the LX3.

Smooth,

Thanks so much for testing this lens. I’m very pleasantly surprised with the pano quality from such a small package.

Have you had a chance to do any low light testing with it? Given the small diameter of the lens, I’m curious to how it compares with the D5000/Samyang 8mm combo.

What do you think would work as a ring-clamp type pano bracket for this camera and a monopod?

Nope -- I think -- this is what UFRaw says:
Warning: XMP toolkit support not compiled in.
Warning: Failed to decode XMP metadata.

ummm.. would be interesting experiment but given how specialized each optic train is, probably the only place the fisheye converter would work is on the NEX.

Hi Judy,

No, apart from my office at night. What exactly would you class as low light for the test. I'll see if I can meet your requirements. I assume you would want this at a higher ISO? Did you see the test DennisS did in his Kitchen at 12800 ISO?

Currently I have mine set up on a NN3 but I think a NN Ring Clamp or Agnos RingT for a Nikon 10.5mm Fisheye would fit. The actual size of these lenses is similar. Should it prove popular I'm sure Nick from Fanotec would make a Ring or Ring Insert to match.

OK, well that sounds correct. Remember the vignetting, corner softness and chromatic aberration I speak of is when comparing to DSLR purpose built Fisheye lenses. The "issues" are nothing like the converter lenses for point 'n' shoot style cameras.

After many lenses and cameras I concur. It is an obvious match, made by Sony for Sony.

Hi Smooth,

I was curious about how the light-gathering capability of the NEX fisheye converter compared with DSLR fisheye lenses. Are the front diameters of the Sony NEX VCL-ECF1 Fisheye and Samyang 8 mm similar?

I’m comparing your previously posted images.





I’d be interested to know how the lens performs outdoors at dusk for sunsets or evening street scenes.

Hi Judy,

The Samyang is larger than the Sony VCL-ECF1 Converter Fisheye in the front element by about 10mm.

The images are clearer and cleaner from the Samyang and Nikkor 10.5mm Fisheye lenses than from the Sony Converter Lens.

I will attempt to capture a dusk photograph for you using the Sony VCL-ECF1 Converter Fisheye in the next couple of days.

I think that until I can afford Photoshop, RAW shooting is will only produce images of lesser quality than the JPEG I get out of the camera. Neither SilkyPix nor UFRaw gets the noise out of the sky like JPEG's right from the camera. Unfortunate. And using NoiseNinja is no different than using noise reduction on SilkyPix or UFRaw. Removing noise is removing detail.

Somehow the camera software keeps detail and removes noise. Must be magic...

Hi Smooth:

Thanks for posting this example. It looks nice!. Will you have other samples to show under different lighting conditions?
