But after testing FoCal 2.6 with my Canon 6D and set of AF lenses, I can verify that it is indeed a relatively painless process. Sounds too good to be true, I know. Reikan FoCal Software Review - Automated Lens Rentals Details: Reikan FoCal 2.6 Overview.

Using this connection it is able to operate the camera remotely, driving it to capture test images, download those images and analyse them for sharpness to determine the best AF calibration value for each lens.I still do but then I came across the Reikan FoCal system. FoCal runs on your computer and connects to the camera using a USB cable (supplied in the box with new cameras). Using Manual Focus Lenses on Canon EOS bodiesUser Assisted Mode.

In addition you don't get any sort of automatic iris operation.At full aperture, and if you set the aperture to, say, f11, it remains fully open untilJust before exposure, then it stops down for the exposure and opens up again. Of course you don't get autofocus, nor do you get any sort of focus confirmation unless you use a special adapter with built in electronics. The answer is a qualified 'yes' in manyCases. FoCal.Left:Bower fisheye manual focus Center: Vivitar 85/1.4 manual focus Right: Zeiss 21/2.8 manual focusA common question from Canon EOS owners is whether older manual focus lenses from other manufacturersCan be used with a Canon EOS body.

The only downside is that it's time consuming and you can't do it with the camera up to your eye.A third alternative is to use a lens adaptor with what is called an 'AF confirmation chip' attached. This is the best and most accurate method of judging focus. A viewfinder magnifier is often helpful.Alternatively, most current DSLRs have a live view capability, which displays the actual image from the sensor on the rear LCD in real time, often with the option of magnifying the image. It is possible to get accurate focus, but you need a properly aligned viewfinder screenAnd good eyesight.

Others can be programmed with a focal length and aperture using the camera to do the programming. The simplest just tell the camera it's OK to activate the AF confirmation light and send a fixed focal length and aperture (usually 50mm f2) to the camera. If you are going to attach a chip to an existing adapter it's very important to glue it in exactly the right spot so that the contacts on the chip align properly with the pins of the camera.There are several types of AF confirmation chips. I have used three of them from different sources (all via eBay) and I have had no issues with any of them. Under these conditions the camera body activates the 'green dot' autofocus confirmation light in the camera viewfinder, so that you get the in-focus indication and 'beep' when you have the lens focused on the subject.While many people have had good luck with the AF confirmation chips and chip enabled adapters, there have been a few reports that they have damaged cameras. Essentially it fools the body into thinking that an EOS EF/EF-S series lens is attached and the lens has been switched into manual focus mode.

In Aperture Priority mode you set the aperture on the lens and allow the EOS body to determine the shutter speed.Since a mechanically adapted manual focus lens has no intrinsic electrical coupling to the body, the body doesn't know it's there and so with most current EOS bodies the LCD display will readout an aperture of '00'. In manual mode you set both the shutter speed (via the EOS body) and the Aperture (via the aperture ring on the lens) yourself. The most popular source is, of course, eBayWhen using a manual focus lens on an EOS body there are two exposure modes which will work correctly, Manual and Aperture Priority. Make sure you know what you are getting if you buy one.

It might be f1.4 or f1.8 or something else. In that case the chip is usually programmed to tell the EOS camera body and aperture. Leave it at '1.0', and if it changes to something else (some bodies will change this value when switching between modes), change it back to '1.0'.As mentioned earlier, some adapters have a built in focus conformation chip. Do NOT dial in the aperture you are using on the lens. However you want it set to '1.0'.

You can either shoot, look at the results, then decide if compensation is needed. There's really no way to tell without doing some tests. It will not use the displayed aperture for any exposure calculation (though it will record it in the image EXIF data.Though autoexposure will work just fine, some EOS bodies may require some degree of exposure compensation - or not. The camera will measure the amount of light actually coming through the lens and in aperture priority will calculate the appropriate shutter speed.

When you mount a Canon multiplier (teleconverter) on an EOS body there is communication between them. The reason for this is complex and has to do with the relative positions of the exit pupil of the lens and the optics of the autoexposure sensors.Clearly using a manual focus lens is inconvenient, but sometimes it can beWorth it if the equivalent EOS lens is expensive, if the manual focus lens is better than anyCanon EF or EF-S series lens (rare, but it happens), if you shoot mostly static subjects orThe use of multipliers with adapted lenses is a little complex. I've found most lenses are pretty good, but a few do need exposure compensation set. If they don't, add exposure compensation in the case of the manual focus lens until they do. At the same aperture both should give the same shutter speed. The other way is to compare meter readings for the same scene between the manual focus lens and a regular EOS lens.

An M42 multiplier on an M42 lens or a Nikon multiplier on a Nikon lens, and then mount the adapter on the multiplier you should have no problem. The lens then tells the multiplier and camera that it's OK and it's a compatible lens, which makes the camera happy again and it will work.If you use a multiplier safe for the lens in the original lens mount, e.g. It wants to see an EOS lens on there.If you have a manual focus lens on an adapter with a focus confirmation chip built in, things should be OK. If you don't mount a lens on the multiplier that says 'hey, I'm a canon EOS compatible lens', the camera body gets upset and refuses to work! In fact if you just mount the multiplier and try to take a shot, you'll find the camera will refuse or report an error condition.

Of course the adapter is them not fully locked onto the camera, so you need to be careful not to accidentally allow the lens to part company with the camera!The focus of a lens is determined by the distance from the lens to the sensor.A mechanical adapter which allows a lens to be mounted on an EOS body and focused toInfinity is only possible if the lens is designed to focus an image at a distance greaterThan that between a standard EF series lens and the sensor in the EOS body.This is because you need some space for the mechanicalAdapter between the EOS body and the lens. If you don't fully rotate it so that it 'clicks' into place it won't trip the switch. Either that or do not lock the adapter completely in the EOS mount.
