Can the L-478DR identify which lens you are using on your camera, to get accurate f stop readings? It recognizes my camera, but what about the lenses

no, it measures the light reaching the subject which is independent of the lens used. It gives you accurate light measurements either in e.v. units, or in f stops. f stops as a measurement of light are equivalent. Differing lenses will affect the depth of field, but the amount of light will be constant and not vary with the lens. Thus, f/1.4 on a 50mm lens will give you the same exposure as it would on a 100mm lens.

If the camera has any automatic modes, auto Iris, the camera will not see the lense, it does seem to work in a pure manual mode. On my D5300, the readout says, " lense not attached", but it will take a picture.The light metering also does not work. For the price I thought it was worth a try.

Hi, thanks question. This lens is contact for FD manual camera. Thanks in advance.

It will only work in Manual mode only. all other modes require the connection to the lens to change f-stop and ISO.

I would love to help, but I can't find this lens to verify how it works. I do remember it worked on mine...

good question. the iris in this unit is theoretically F1.0 and should pass 100% of whatever the lens is giving you to begin with with w/o loss until you close it down.. just not something I ever worried about.

I will answer as soon as possible. I am still waiting for my filters and adapters and LCD covers before I take my camera anywhere to take any photos. I just want to be safe. I scratched the lens and LCD on my last camera when I fell down, so I am trying to be extra careful. I will keep this email so I can remember to answer your question. Have you tried manual though? Going to the highest ISO would probably help with that.

Because Canon dSLR cameras are unable to auto focus if the f-number is greater than f5.6. So, if you have a lens that's f4 and you use the 1.4 extender, then the result is f5.6 and auto focus still work. If you have the same lens that's f4 and you use the 2x extender, then the result is now f8 and auto focus will not work. The only time this is not true is if you're using the Canon 1DX camera body but since most people use the 5DMII or 5DMIII or the crop-sensor bodies, and lenses that typically have f4 in the lens (as do most Canon zooms), then the 1.4 extender is the best solution. I can say that on my 5DMII with my 300mm f4 L lens, the 1.4 extender is a perfect match (and it works perfectly with my 135mm f2 L lens as well).

Yes, at the 18mm setting It may report an error. It happened to me only once, I didn't find out if it was a camera or lease issue.

1. re focal length conversion--no.2. re light loss--I have not noted any--but, frankly, I am usually using any / all of my adapter with a fixed f-stop setting or with AE.

yes, if the particular lens you have will let you manually focus and set the lens f stop.

Thanks for the info. I figured that out , finally. Don't know who gave me the misinformation about exchanging lenses, but I purchased the K-7 with the proper lens. Thanks again.

Hi! Fit the adaptor to the body first; make sure its locked..then mount the lens. Be careful to line up the marks by loosely turning the lens over the adaptor otherwise, you can snap the pins that control the aperture in the lens. The adaptor WILL NOT FIT FL lenses, just FD...It you are having issues with mounting the adaptor to the body, over the work LOCK on the adaptor is a red dot. That the matching point to the body..Hope this helps!

If it's the model that sets aperture electronically from the camera, then it should meter. If there is no electronic link for the aperture setting, then it won't. You may want to visit a big-box store and try the lens on a store sample. If the lens has an aperture ring, set it to the narrowest aperture (highest f number) if there is no specific marking for automatic setting.

It sounds like TBone knows more than I do about your specific camera than I do. Sorry if my answer was confusing.

The best way I've found to verify which lenses work and which adapters to use is check at both Fotodiox and RainbowImaging in the US. If they have an adapter for the lens, it probably works. You can then e-mail or call them for verification if you're not sure.

I would look to see if it says "IS" -IS stands for image stabilizer and often, the cheaper lens doesn't have this feature. Also the "II" should be an indicator of how new it is. The older models didn't have the "II" in the name.
