Anyone using a Samyang 14mm F2.8 RF mount or Laowa 15mm F2 RF mount lens?

I am possibly interested in one of these lenses.

Anyone using one or the other and care to comment on them?

What is the RF mount Greg? I have this lens with the Canon EOS mount but am not aware of an RF option. I see that the Bintel site lists a ‘Canon M’ option which I’m guessing is for the mirror less range of DLSRs.

As for the performance of my ‘EOS’ version, I am very pleased with it. I use it primarily for wide field Nightscape work with my Canon 60Da. I do step the lens down to 5.6 to address improve the coma around the edge of the field and at that setting I am happy with the results that I get.

Here are a couple of links to recent images taken with this lens:

Hi Rodney,

RF mount is the new mount Canon introduced when they made the first mirrorless R camera.

It's wider than the EF mount and has more contacts.

There is an adapter from Canon that goes from EF mount to RF mount
which I use. That is handy as I also have a Sony E mount to Canon EF
adapter which enables me to buy a lens with an EF mount and use it on either my EOSRa or Sony A7R3.

Nice round corner stars in your image.

The model I saw on lenstip.com review was Samyang 14mm F2.8 ED AS IF UMC. It showed virtually no coma in the corners of full frame which is amazing at 14mm. There seems to be several Samyang 14mm F2.8 models. The XP F2.4 version costs more but seems to have more reliable quality control which has been an issue in the past with Samyang 14mm F2.8 lenses. They are cheap but not really quality controlled so it's a lottery ticket if you will get a good one or not.

That may have changed with these later versions.

Greg.

I run the older non AE Samyang unit on a Nikon full frame camera and other than spending a long time to find the accurate infinity focus point for Milky Way images and marking it, the lens itself is a remarkable lens for wide field photography of the night sky

The earlier non AE units did have issues with infinity focus, my first new one was promptly returned and replaced as it would not reach infinity focus but the second unit I got is perfect as long as I totally disregard the markings.


I do believe this issue has long been addressed with the newer AE models for both Nikon and Canon versions.
As for value for money, at the time it couldn't be beat when considering I paid $300-$400 for the lens new and an equivalent Nikon lens was $2500 or more.


They are STUNNING images Rodney!
