Duke Pham. Great quality on budget. Love the vintage look in the images. Highly recommended. Caitlynn H. Circular Haze? How to fix? How do i get rid of the circular haze in the center?? Seems to ruin every shot. Michael Ray Sr. Worth the money. I have a few FD lenses that have still have life in them. This product wsa easy to install and use.
Load More Q Will this adapter work with eos rebel t? A it could work with eos rebel t Q I have a canon ae1 camera with alot of lenses will i be able to use those lenses on my canon eos t7 camera? The one I purchased works without a hitch. From a F1 to a 5D Mark 4 with no issue. Q Will this fit on my canon 60d? On their website Elephoto say " First a little about the methodology.
With a Canon FD mount lens it's hard to compare results with and without the adapter since FD lenses can't be mounted on an EOS body without an adapter! Since the adapter acts as and in fact is a 1. High quality machining, well blackened surfaces to minimize reflections and multicoated optics.
The optical assembly is easily unscrewes to convert the adapter into a macro adapter. Overall it seems to be a very well made item. Without the optics the adapter acts as about a 15mm extension tube. With no optics in the adapter, a mm lens could be focused to a maximum distance of approximately 8ft and a mm mirror lens which allowed focus just "past infinity" as many telephoto lenses do could be focused to a maximum distance around 50ft. Magnification The original Canon adapter acted as a 1.
The "test target" was the back of a lawn chair! Actually not a bad target since it contains a lot of both high and low contrast fine detail. Below is a typical full frame 20D shot. All focusing was done manually by observing the viewfinder image using a 2. From previous testing I know that the focusing via the viewfinder screen in this particular camera is very accurate. It mounts just fine with the lens set to the close focus position, but if the lens is focused towards infinity there is mechanical interference between the adapter and part of the lens which moves backwards as focus is extended.
However you can still us the combination up to a distance of maybe ft. Below are the results with the lens set to f1. Quite clearly the results are f1. Very low contrast, soft images. Not perfect, but contrast stays pretty high.
Things improve slightly at f2. Apertures in parentheses are with the adapter attached. Again it's obvious that there are problems wide open. By f4 things look a lot better and the image is pretty good at f5. The images are quite similar, but the one shot with the Tamron 1.
Genesis mm f5 APO Fluorite telescope This telescope is as good as any mm photographic lens, probably better than most! If uses a fluorite corrector element to minimize chromatic aberrations in a Petzvel lens 4-element configuration. In the center is the image shot using the Tamron 1. All three images are pretty high quality, showing that with a good telephoto lens at f5 the adapter is capable of yielding good results.
Again it's evident that with the lens wide open f4 there is a significant drop in contrast.
