Since I couldn't even focus my image, does that mean I should buy an adapter with the glass in it? Would that make a difference.

The adapters with glass will allow you to focus to Infinity, but with some loss in image quality.

When we first got ours we had the same problem with clarity and had searched all through the menu options with the blurry image trying to find it. The plastic part around the lens is what you use to focus the image. The first time it felt like that wouldn't move but if you keep at it gently it will work and then you won't have any problems moving forward. Once you fix the clarity you can read the menu better to adjust the image size. Good luck.

I get it too.... Are you using the adapter for it or did you screw it directly to your camera? I came to the conclusion that using the adapter was the problem. I went to a camera store and tried a fisheye that actually fit my camera without an adapter, took a picture and it didn't have a shadow.

I can't give you any advice on that. I was looking for an adapter for a Mamiya camera lens and what I tried did not work (as I was told before I bought it).

I wouldn't think that would be a problem. You're going to pre-focus, so your camera will know that. Should work.

I'm not sure if the lens will work without an adapter sold by Opteka. I would caution you about this lens in that it is difficult to focus and get your exposures correct. Also the lens is not suitable for any subjects that are in motion as the aperture settings are slow and require long exposures. Hope this was helpful.

Well there are two possible problems. One is that you may have such a small magnification, such as anything smaller than a 50 mm lens, that you are too far away to actually discern any detail. Another problem that you may have is that you forgot to loosen the knob that locks the focuser. This is located near the bottom of the place that you put your lens in. If it is tight then when you turn the focuser, nothing will happen which would lead to blurry views. Hope this helped! Clear Sky's

As long as you have the adapter on the camera, you're always going to have that tunnel vision unless you zoom in till it's gone. If your are thinking of getting this kit, I would say skip and save your money. It adds nothing at all to the use of the camera.

It is really hard to tell whether it is the adapter or the lens itself. The images I have taken so far are reasonably good. I am using Vemar and Mamiya lenses from my film days. If the old manual lenses you have are of good quality you are likely to get good images. There doesn't seem to be any drop off in light transmission. This adapter has a single, clear piece of glass in it so light loss, if any, should be minimal.

You will need to use "active" glasses. I have both Sony and Toshiba which both work.

Don't bother, I bought this for mine and the camera lense was unbelievably blurry. I sent multiple emails with no response, I eventually had to file a claim with amazon to get my money back

Hi, though the adapter should work fine I would recommend purchasing one of higher quality; I bought this adapter and after about four months of relatively heavy use it started to fall apart. Specifically, the locking mechanism on the lens to adapter side sometimes disengages and the adapter ring has now begun to separate into two parts, the result of which is that the lens can sit at an angle from the camera body if not propped up with a finger. However, if you're looking to save money the latter problem could possibly be remedied by using a tiny screwdriver for eyeglasses, though I'm not sure as I have not yet tried.

Autofocus is awful with this adapter; most likely on paper but not in practice except under ideal conditions (high contrast, still subject)

You will need an adapter and it will work. In this way you may lose some auto focus speed but not image quality :)

If your telescope is of the Newtonian type you might have a hard time getting the image to focus, or even not being able to focus at all. If this happens you would need a different adapter with a Barlow lens or to move the main mirror inside the telescope.

Twist the lens. It may be that it is indeed too low to get a good focus. If you twist the lens on mine, it comes into focus.

I tried this on camera lens and its completely failed, not sure how good it will work with ur glass...
