Is this 2x teleconverter by Digital Optics any good?

I see this 2x teleconverter on sale often on EBay. It comes out to about $100 including shipping. Sounds like a lot cheaper than the B-300 that everyone talks about. I'm tempted to buy this, but I'm also aware of the saying "you get what you pay for". Has anybody bought this and does it do a good job? Do you have any regrets and would you buy it again?

Here's the description on the ad:

Lens is made by Digital Optics (A company specializing in lenses and filters). Here is what you will be getting: (1)- Digital Optics 2.0X Pro High Definition Telephoto lens, brand new in its original box. Titanium series. 58mm rear thread. 62mm front thread ...

I bought it, it does a good job and yes, I'd buy it again. Have had no problems at all. Regards, Gary

Gary,

I'm glad to hear that the teleconverter is working out for you. I wonder how come not many people mention this lens in the forum. It is because the brand is unknown or perhaps because its a relatively new lens on the market, and the B-300 has been around longer?

I'm strongly considering buying it for $100, but I hesitate because I just don't know enough about what to look for in these teleconverters to make an educated decision. Someone had posted a some sample pictures a while back but I forgot to bookmark it. Do you have any sample pic?

Is anyone else using this 2x?

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.

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

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?

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

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.
