Related Questions and Answers

Q: 1. Will this work with a Canon 70D and Sigma lenses?

A: yes with no problem.

Q: 2. If I understand, I will have to run the program with each of my lens 9 Nikkor and Tamron G2. Is the camera record and keep in memory the correction result per lens ?

A: Yes. Each lens may have a different optimal AF Fine-tune set point. The last step in the FoCal is to enter the optimal AF-Fine tune number for that particular test. The (Nikon) camera will remember the setting for each lens tested and will automatically load that number when you put the lens on the camera. You can always change it manually, in the camera, for the lens that is on the camera. Test Zoom lenses at different focal lengths. You may have to compromise on the "best" setting since Nikon cameras only store one correction number for each lens.

Q: 3. What's the difference between the plus and the pro?

A: Focal Pro has the additional functions:Aperture Sharpness find out the sharpest aperture for your lensesAutofocus Consistency check out the autofocus performance of you camera.Dust Analysis find out how much dust is on your sensor, and which aperture it will start affecting images.MultiPoint Focus Test automated comparison of many focus points, and even full individual calibration.Also, FoCal Plus will NOT allow calibration of lenses or a combination of lens & teleconverter with an effective focal length longer than 400mm. For this, you will require FoCal Pro.

Q: 4. Will these work on Nikon zoom lenses?

A: Yes, you can use this product with Nikon zoom lenses.

Q: 5. In the product pictures, I see several wires running between the laptop and the camera. What sort of hardware do I need to connect my camera to my computer?

A: The USB cable that came with the camera connects the camera to the laptop or computer. In some cases the software is able to control the camera and "enter" the correcting factors automatically, in others you have to manually add the numbers before the next step is performed. In this case make sure you have a very secured tripod/tripod head to avoid any movement otherwise you will need to start all over.

Q: 6. Are the callinration settings potentially impacted by an extender? If so, does Cannon save callibration settings with and without the extender for the same lens?

A: Yes, the calibration settings are impacted by an extender. I use an extender with my long telephoto lenses. My Canon camera -5DMkIII- did save the settings for with and without the extender.

Q: 7. Does it only work with Nikon or canon lenses

A: Hi Paul, Thank you for your interest in Reikan FoCal. I think the question is answered but just to add, FoCal works with pretty much any / all Canon and Nikon DSLR cameras which allow AF microadjust / AF fine tune, you can double check the list of supported cameras by searching google with "reikan focal supported cameras". In terms of the lenses themselves, any auto focus lens which is compatible with a supported camera will work. These can be Canon, Nikon as well as 3rd party including Sigma, Tamron and Tokina lenses. Best Regards, Dave

Q: 8. Is here an IOS version?

A: No, pc or mac only.

Q: 9. Will it work with a Sony a7ii

A: According to the following page on Reikan's site https://blog.reikanfocal.com/2015/05/reikan-focal-2-test-release-2-now-available/, we should be able to use Reikan Focal Pro in “File Mode” with Sony A7 series files. However, I get an error message saying it is an unsupported camera whenever I try. From the page: “So if you want to calibrate a Sony 70-400 using an LA-EA4 on a Sony A7 camera, or check out the aperture sharpness results for a completely manual vintage Zuiko Jupiter 8 lens, you can do it easily now with File Mode!” Note: I'm using version 2.4 but this was announced in version 2.0

Q: 10. Is the version 2 pro software still as buggy as many of the comments suggest?

A: The software version that I downloaded from FoCal was ver 2.4. No CD comes in the box. I ran the software on a MacPro with MacOS 10.11.6. I could not get the software to work. The software wanted a driver from the Apple developer library. Contacted support via email. They could not resolve the issue. Returned the software to B&H who thankfully issued a refund. I now do my lens calibration manually with a calibration target.
