Related Questions and Answers

Q: 1. Is the 150 mm target supplied large enough to calibrate lens's larger than 400mm? What size is optimal?

A: Yes, it does calibrate lenses 400mm and over.

Q: 2. Does it work with Digital Bolex? What does MP camera mean?

A: This is a lens designed for cameras that record in a format up to 720p. MP means it's a megapixel lens. This model is a 1 MP lens. If the format being recorded is any higher this lens is not recommended.

Q: 3. Will this work on a c-mount Bolex H16?

A: yes it will work on a c-mount Bolex

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

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

Q: 5. can this be used on a Canon 7D mark ii with tamron lenses?

A: Yes........

Q: 6. 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: 7. Does the current version of the software support the new Canon 1DX Mark II? Or is a software update needed before it can be used?

A: Probably not. I just opened it and checked for updates (there weren't any). It's been a while since I last saw one and that update, as far as I understood, only really corrected bugs and didn't add any cameras.

Q: 8. How is the software supplied? Online download or CD or USB or which? Many new laptops do not have CD drive-thanks.

A: The software is downloaded from Reikan's website.

Q: 9. 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: 10. Does a printed target come with this Purchase of Focal Pro 2 from B&H?

A: Yes. Also when registering online, they have other target downloads that you can print yourself

[f/2.4 to 11] A great, sharp ultra wide lens for the BMPCC with low chromatic abberation and distortion. It covers the BMPCC and Panasonic GH4 4K sensor. Downside is that this lens has no front filter thread, but if you search diligently enough one of the anamorphic lens holders will clamp onto it.

[4.7mm] This lens is great if you need a wide angle with superb light sensitivity for an extremely affordable price ! Sure its build quality can not match more expensive lenses. But it gets the job done and pretty well at that! Even nice for macro! If the camera is more than 1.3 megapixel this lens might not be ideal! I used it for machine vision applications.

[Fixed Focus] I bought this lens to use with a In-line process camera for my laser processing work station. This fixed focal length long focal length lens worked perfectly and I was able to zoom the work area with a clear image. I recommend this product srongly for imaging where the working distance is a constraint.

[0.895 lb] I use this lens for video conferencing. I modified some Logitech C920 cameras with a CS mount + switchable IR filter. It works great.

[4.7mm] Great wide angle lens with extreme light sensitivity! Super affordable which makes the build quality a little questionable. This does not affect picture quality though. Great lens that gets the job done. I used it for machine vision applications.

[Fixed Focus] I use this camera with a Point Grey Research Flea3 for LOLA video conferencing. It's very sharp and wide enough for most uses.
