I got a Nikon G to Canon EOS K&F Concept adapter, brand new, for 20 bucks off eBay, so I could use some of the Nikon mount lenses I have left with my Canon 80D, and it does its job nicely.
The white piece lets you adjust the aperture, but, fair warning, there’s no indicator on the adapter or any Nikon G lens to tell you what the heck you just set it at.
This is not a deal breaker, because not only does the sensor in a camera like the Canon 80D do a great job handling the exposure, but with practice, the amount of light coming through the viewfinder will let you make a pretty good guess at what f-stop you’re at.
For someone like me, the adapter is extremely useful, but if you’re one of those people who think the camera should be totally automatic, save your money. This little beastie is completely manual. Not only does it force you to select your aperture, there’s no autofocus.
–While I’ve ever heard of a Nikon to Canon adapter that can give you autofocus, some of the more expensive adapters have a chip in them that will at least give you a focus indicator.
Meanwhile back at the ranch, here are two of the lenses I’ve been testing.
The Sigma is a bit long in the tooth, but it has good glass, manual f-stop selection and most importantly, the adapter goes on and comes off without a hitch.
I don’t know about you, but when I’m shooting extreme close-ups, I use a tripod, so I don’t need IS, I focus manually so autofocus is a waste, and I use the aperture markings on the lens for depth of field. That leaves the camera dealing with ISO and exposure, but only when I let it. So for me, at least, the only difference between the Sigma and a Canon lens is that I have to remember to put the adapter on the Sigma. –Yeah, yeah, I know, the quality of the glass, but for what I do and for the price difference, I’ll stick with my Sigma.
The 35mm is a different critter entirely. Sure it functions well with the adapter, and it fills the hole between my 10-18mm and my 50mm, but I’m one of those people who tends to shoot really wide or really long. Which is probably why I left it tucked away in a drawer for so many years. Still, if I ever need a mostly manual 35mm, I’ve got one.
In the meantime, here’s a handheld 1:1 macro taken with the Sigma 105mm lens. –It’s not exactly a keeper, but you get the idea.
The EXIF data doesn’t show the aperture because the adapter lacks a chip to allow the lens to talk to the camera, but I tend to shoot at f8 or f11 si it’s all good. Beyond that, I relied on the camera to set the exposure.
And I just thought of another selling point for the K&F adapter. It lets me use my already manual tilt-shift lenses, which is a great excuse not to sell them.
As a side note: I went into the camera and limited the iso to 6400. I’d rather have a longer exposure time and less noise. –This may or may not be necessary with the newer processor. I guess I’ll have to make a few test shots to find out.
