Anyone tried cheap fisheye adapters?
May 6, 2011

Hi all,
I'm tempted by those cheap fisheye lenses you can find on ebay.

They have usually a macro lens + a fisheye lens and cost around 30 bucks.

Multiply factor ranges from 0.25 (cost double) to more common 0.40-42-45.

Anyone can give some report on them?
Image quality degrades?
In which terms? Sharpness, CA, vignetting..

Note:

please avoid answers like "You get what you pay for" or "if you want decent quality go for sony adapter" or "a 30 $ lens is bad quality for sure", I'd like to know informations from real test by users that have them, and not just speculations.

The quality is very, very poor.

I can post pictures, but it suffices to say that the CA of these adapters is horrific, the picture only has details around the center - the edges are very smeared.

If you shoot JPG mode, the NEX processing algorithm will try to 'smooth' out much of the poor quality, even in the center, resulting in a loss of detail and a 'water-color' look & feel reminiscent of the much smaller sensor P&S cameras.

There is also no correction software to recover some of the poor quality.

Really, the two Sony adapters, ECU and ECF, are worth their price.

  • The ECU converts the 16mm into a 12mm wide angle lens

  • The ECF converts the 16mm into a 10mm fish eye lens

Spending the extra $100 for the ECF over the cheap adapter is soooo worth it.

They do not vignet on the 16mm lens, but they do on the 18-55 - horribly.

Same applies to the tele converters.

If you only want the macro ring, I think that you can get these for a lot less.

I received the Sony VCL-ECF1 Fish Eye "converter" from Amazon yesterday. With Amazon Prime, I had it shipped next-day for $128.xx. It's pretty nice. I've only played with it at the house, but I plan to shoot with it this weekend.

it would be nice if you can post somne photos shot with the cheap adapter.

Actually I don't have the 16mm, I was planning to use it on my 24 and 28mm olympus zuikop lenses, which have the same 49mm ring.

so, I think that the sony wide could have heavy vignetting (if it fits) on them, and that would be awful after spending 150 euros.

vignetting means you have to crop the image, so you end up having the same field of view you had without the adapter but at a lower resolution!

so, 30 bucks can be spent for a try, 150 no..

but, if samples from someone are really awful, I could give up before trying!

The Sony wide (or fisheye) only fits the SEL16F28. It does not use the 49mm thread, rather it 'clicks' in a bayonet fitting around the thread.

Rather than the 'cheapo's', try something like the Raynox (0.66x or 0.79x). They are 49mm thread and sell for about $100.

Check around you, a photostore may carry them and let you try them out.

Your much better off with the Sony wide angle and fisheye adapter for the 16mm lens. I tried the cheapo's in the past and have never been impressed with the image quality. The other concern about fleaBay is the quailty of the product. I've gotten some real junk over there. It's kind of a crap shoot.
