EF-EF adapto

Hi everyone. I have the EF-EFR adaptor for drop in filters. I think it would be a good idea for someone to make a EF-EF and a EFR-EFR adaptor for the said filters. It seems a shame that the drop in filters are only available for what i would think is a reduced number of cameras. Does anyone else think the same or am I just being daft.

 

the problem with making an adapter with drop in filters for a like to like system mount, ie, ef-ef and efr-efr is you will be extending the lens away from the point it is designed to focus on the camera sensor, this will be the same effect of adding a extension ring which makes the lens great for closer up subjects but you loose any sort of distance focus

for my system , ef-m i do have an ef-m to ef drop in filter adapter and yes they are very useful

one way it could be done is to add lens to the said like to like adapter so it corrects for the added focal but i'm not sure it would be the best option as there would be some light loss

your best bet is a filter that clips into the camera infront of the sensor, not as easily adjustable as the drop in adapter but still eliminates the front of lens problems

you could make a suggestion to the Japanese department for them to put a drop in slot on the bodies of cameras, i have previously gotten replies from that department with suggestions

 

Thanks Canadian for your reply. I agree with all you say. It just seems that all the companies that sell this system only make it for certain cameras and not the whole range. Perhaps the think that DSLR,s are going to be obsolete. Len

 

nope, its not that, its the fact you not adapting a lens you are using the same mount to mount
there are however lenses that have the drop in filter system built into them, but they are more modern ones and higher end lenses.

as for obsolete, i use 1950's lenses on my canon M50,
