So the EF lens stays at its maximum aperture the whole time while using this on an NX camera?

yeah, you can only change the aperture if you put the lens back on the canon camera

Maybe due to focal length they are classifying it as fixed zoom but I would disregard. Focal length is equivalent to 45mm on FX.

Yes..it will meter the light properly with the camera, and the auto focus will work...IF you buy the new full frame adaptor, for an E mount camera, that will adapt an A type lens..BUT..remember, the A mount lenses do not have the steady shot feature in them...the E mount lenses do...(New full frame E mount adaptor is: Sony LA-EA4) Also, remember that if you use an A7, the lens should be a full frame lens..A mount with adaptor, or a full frame E mount.. lenses now have the designation FE for these new full frame E mount lenses.. There are some black areas, or distortion if you use the old, regular E mount lenses that we used on the NEX series cameras.......

I use this lens with the NEX7, and it has become my most used lens. Some slight distortion on close ups but very predictable and does not mar the great quality shots. This is an extension lens, you can only use it with the basic wide angle. Together they make a very good flexible combination, and this clips on and off in seconds.

No. You have to use the manual focus. I do not think this is an issue because the NEX has focus peaking where it highlights the areas that are in focus.

I have two Nex-7 and a Nex-3 cameras and I have not noticed any "purple fringing" with this lens. My main issue with the lens is that, even stopped down to the max, it does not seem as sharp as it should be. I have a SONY 16mm f/2.8 Wide Angle and the Rokinon is no where as sharp as that lens. Maybe I am expecting too much. Don't get me wrong. I use and enjoy the Fish-eye FX this lens provides, soft or not.

No, It doesn't go black ever while it's selected for viewing. In fact I photograph large waves with continuous focus and slow or fast sequence and it's flawless. Wouldn't do without it. The resolution is great and the view is large. It does show the stop action of stills for a second which I like as I can see if I got the shot. The focus is almost instantaneous on The EPL 5. I have yet to get off the default settings because of the complexity and the fact that I get what I need without it. But likely, the subject or timing, or presence of instant review could be customized. Manuals are available for free download online as PDF. Luckily, I got the viewfinder on sale at Amazon.

I don't have issues with lens creep at all. I've owned it for a couple of years now. It's on my camera 90% of the time.

Most DX lenses are "G" designated and missing the aperture ring. This adapter does not carry any data from the lens to the camera. It also has no mechanical connection. Therefore, most DX lenses will be stuck at the smallest aperture and photos would be severely underexposed. With this adapter, you must focus and set your exposure manually. If your lens has an aperture ring and focus ring, this well-built adapter works fabulously. With focus peaking, manually focusing is a pretty quick and easy task. Keep in mind, the exif data will be missing info like aperture setting.

Hello, question as well - because this is for an EF mount, it should work on my full 5D correct?

The apertue setting is set to f22 on the lens and then you can change the aperture via the camera. That is normal for all D lenses.

Yes and no. There have been a few alarming SDM/Autofocus no-work moments, but a remount of lens and camera on/off has always fixed them immediately. We both use this lens all the time, so counting the one I smashed, we have direct experience with 3 of them.

No, Due to sensor size you do not want to use an EF-S size lens. There would be a vignette about half of the sensor size even if there was an adapter to use. There would be a big black circle around your whole image.

Thanks for the explanation, Les. So, it seems that as long as the IS is turned on, in-camera, it doesn't matter whether it's on or off on the lens. I made do some A/B testing to see if there's a difference with the lens switch on/off while the setting is switched on in-camera.

This is a speedbooster. The maximum f stop is multiplied by .7. For example if you have a f2 lens it will increase the light gathering to a f1.4. Also makes the lens wider by 0.7. If you attache a 10 mm lens it will be as if you attached a 7 mm lens times the micro 43 conversion factor.

Apparently the image quality is higher on this lens that's why I bought it. I really don't use the Fn button on the other NX lenses that much. It's a cool feature but not really needed to take a good picture.

I don't see it because it does not happen with the kind of photography I'm into. If you like using 8-10 stop ND filters to do long exposures in daylight, or like to open your aperture all the way and point directly at the sun, then you will have issues with it. It will not affect most users in normal practical situations.
