Does this adapter allow lenses to focus past infinity?
824028
I believe so, because it adds a gap between the lens and the sensor. For example I was photographing the moon the other night. This would usually mean just setting the focus to infinity and going for it. However, with the adapter on, the moon was in focus some way back from the infinity point on the focusing ring, indicating that infinity has moved further away, so to speak. Hope this helps. :-)

The focus is infinite. The closer the lens is to the object, the higher the magnification. It will also work on some android devices. A magnetic dial indicator base from harbor freight can be a good stand.

Technically, no. Not ALL 1.25" eyepieces will achieve infinity focus. Eyepieces from Celestron's X-Cel LX line can definitely do so, so do those from Pentax. There are probably other brands that would also work--just do some research. The following information comes directly from Celestron: " The Regal F-ED series spotters have a 1.25" eyepiece holder and the OEM-supplied zoom eyepiece is easily removed from the scope by a twist of a knurled ring. Because 1.25" barrel-diameter eyepieces are very widely available, you can use other eyepieces with your Regal. However, not all eyepieces will work with the scope because of the design of the internal focusing and 45-degree prism assemblies. This places the image plane for the spotter's objective at about the back of the knurled ring. So the Regals have a small back focus distance. Eyepieces that have long 1.25" nosepieces or barrels (with field lenses recessed about 1 inch or more) generally won't be able to achieve infinity focus with the Regal spotters. Nor will 1.25-inch- type T-adapters or Barlow lenses work with the scopes. The OEM zoom eyepiece has both a short nosepiece and its field lens at all magnifications is close to the end of the nosepiece tube. Eyepieces that will work with the Regal will have similar physical characteristics. As an example, most eyepieces of the Celestron X-Cel series have these characteristics and will work with the Regal F-ED series."

I own the adapter, I own old AI lenses and EXPECT the combination to work! I have yet to purchase the X E1. (so I cannot tell you for sure)

Thank you for asking. Yes you can, but you will need to manually focus as there is no electronics in this adapter.

Not is a problem, is normal. Adapter complete is for telephoto (extended lens). Half adapter, without final part, is for wide angular (compressed lens). Tunnel effect is present if you use the adapter without this considerations

I'm not exactly sure what you mean by "zoom-to-focus" but what I can tell you is that manual focus works great with the adapter. Auto focus on the other hand doesn't work as well as it would with a native lens. It hunts for focus a lot and sometimes doesn't get what you are trying to focus on in focus.

Yes - but read the description carefully. It will mount a Canon FD lens ( which is the lens used on a Canon AE-1) to a Canon EOS but will only be useful for macro photography. This adapter has no glass in itso it will not allow infinity focus. To adapt a FD lens to a Canon EOS for infinity focus i.e. "normal photography" use you'll need to select an adapter with a glass lens. There is much debate on the quality of the photos when using that type of adapter. From my own experience I've found that some FD lenses and EOS cameras seem to work OK and some have provided disappointing results. Yes - but read the description carefully.

NO. Warning, i still can't use the lens... The sealer's made a mistake and send me the wrong adapter!!

Yes it can. I'm currently using it with the 50mm Nikkor-S.C. Auto, I lose a little bit on infinity focus, but for the most part it works like a charm.

Bonjour,I have use this adapter with 2 Sigma lenses one 10 20mm and a super long rage 120 400mm Pentax k mount on my Sony Nex 6 and it work great. It alow use to control manually the overture and you keep the infinity focus. Sincerely Jean Marc. PS hope this help and sorry for my spelling I am french.

This only will work with the lens specified.I bought it but it did not work with my universal lens.The adapter itself is a nice piece of metal.Hope this helps.H.B

Basically, when you point the camera to a distant target (like a cloud, stars or the horizon) and you can focus on it successfully. Keep in mind that there are lenses with distance rings that can 'focus' before or past infinity. This doesn't necessarily mean the lens is not calibrated, in some lenses this is to allow for thermal tolerances.In case of adapters, if you have a lens that can focus to infinity just fine in a camera; but can't in another once is attached to an adapter, then the adapter itself might be defective. While rare, it doesn't take much of an error on flange distance to cause focusing errors in that case.

Presuming it's an m42 mount lens then yes. The adapter has the infinity glass insert and is only 11 bucks, go for it.

Its infinitely variable as far as I can tell. Its like twisting a knob. I don't use this very often, only on one particular lens. I almost forgot about it. Thanks for reminding. No issues with this at all. Just guesstimate only for aperatures.

Hello, to be honest I don't know, but I think YES, depends of the Lens you will add (for example mine its Macro which DO NOT retains de autofocus -see manual there are new one it does- ) the adaptor does not affect. I hope this info can help.

I'm using it with my Nikor 1-300 and 18-200 lenses. Works like a charm. I'll likely sell my micro lense. Much better than teleconverters, as there is NO change to f stop.
