Re: Is this 2x teleconverter by Digital Optics any good?
Hi,
I think it says 2x on the box because they're full of it! I was conned into buying a wide and a telephoto with my F707. These lenses are complete trash. They are the lenses made for $10 each somewhere in Japan so these online stores can push them and make a profit off their heavily discounted cameras. I've seen online stores claim they cost anywhere between $70 - $600! It all depends if they're just trying to make it seem like they're giving you a really good deal.
I'm sending my lenses back - and they're giving me my money back I'm glad to say. You can't blame these guys! I bought my F707 for $850 with them after phoning these shadey NY stores with websites. These guys are quite genuine.
So, I'm still hunting for a good wide angle adapter for my F707. I want at least .50x and minimal CA effects. The Digital Optics is not good - but after seeing samples of the official Sony, it's actually better than that one! CA can be corrected, but the main problem is that you can't get good focus because of poor lens quality.
As for the telephoto. It's not x2, and it blocks the IR emmitters on the F707 (not that they would extend that far anyway) The night vision doesn't work without them too well! So, don't think that your F707 will turn into some spy cam with a telephoto, that feature is good for framing closeups and that's about it.

Oh, one more thing, the box in the photo is for a Vision Optics
lens. However, the Digital Optics lens box also says 2x.

Yep, that's what it says on the box.
Now take a picture of something (say a building in the distance)
with and without the lens. Display both pictures on your monitor at
100%. Use a ruler to measure the length of something in both
pictures (say the width of the building). The measured value in the
photo with the lens will be 1.35x times the measured value without
the lens.
I don't know why the box says 2x. Does anyone?

So far as I can see, the lens is 2x .... at least that's what it
says all over the box. Here's a picture of the lens, box, etc

I'm using the Digital Optics 2x and I'm satisfied with it. My only
complaint is that it's really only 1.35x with the 707.
$100 is a good price; I paid $189 for a new one.
Some photos I've taken with it are posted in my galleries:

The animal, bobcat, moon, and HC bird pictures are all with the DO 2x.
