The Canon FD Adapter for the Sony Nex series (E-Mount)

There are many adapters on the market for the Sony Nex, from the low-quality chinese items sold on Ebay, to better constructed models with higher prices. Being based in Italy and as an amateur astronomer too, I chose the ones made and sold by COMA (Costruzioni Ottiche Meccaniche) by mr. Adriano Lolli, a very well known name in amateur astronomy circles, for his astrophotography accessories and rings.

As you can see on that link, there are many lens adapters for the Sony E-Mount used by the Nex series. We'll cover specifically the Canon ones.

The Canon FD Adapter

Ring of conversion, Link, Adapter objective Canon FD ... baionetta E mount . It allows to climb on all the objectives, telescopes, microscopes and other optic tools with photographic attack Canon FD on the serious focameres baionet E mount . The photographic objectives Canon FD climbed on on the photocameras E mount preserve the mass to fire to the endless one. Note, any tramissions of automatisms is not had. You photographs in manual. Warning: before verify the compatibility of your camera for the use of fittings. The functioning of reflex with rings adapters can vary from model to model and brand to brand. Usually a camera has only modern electrical contacts that interact with the target, noting the diaphragm, light and fire. While optical adaptations have no contact or are totally different. However they can not send information to the camera, so some machines do not work automatically or, in very exceptional cases, not taking. Generally work in manual mode, even in some must vary certain parameters settings so they can make the shot. Some instruction booklets explaining the mode of operation of the camera when using instruments such telescopes and optical microscopes or old. The verification system can be made simply by removing the lens from the camera, at this point try to make the step with the change of time for the right exposure. By changing shooting mode generally on M will observe the operation thereof. For more info write Realized in resistant full metal They are available other types of adapters for cameras.

The adapter is of very good build quality, note that COMA doesn't simply resell cheap chinese stuff, they manufacture the adapters in Italy in their lab, and it shows!

The iris control is the one on your FD Lens! The adapter simply enables a mechanical switch that unlocks the iris on the lens to work normally as it would on a Canon FD camera. Except the "A" automatic aperture position doesn't work, you will have to always adjust the aperture manually. However, I haven't found this to be a problem at all, in fact, since there's no autofocus anyway, I prefer using FD lenses with the Sony Nex-7, because setting the aperture on an EF (Eos) lens with the adapter is quite cumbersome and have side effects, like strong vignetting. See my post on the EF Adapter here for more informations.
