About this deal

Samyang does not publish the MM (Maximum Magnification) spec for this lens, but some observations can help us get close to that value. Also note that chipped versions of this lens are available, supporting some additional features including autoexposure and focus confirmation, potentially at a higher price. notes: Handheld with built-in Ring-light used. This lens could also be used CLOSER than I was using it here... but these are STINK BUGS and we were all nervous with the proximity to one another.

I do not recommend the use of Extenders with the EF 135mmL lens because although they will fit, the lens design is possibly just a little too old to allow trouble-free experiences and the Extenders seems to trigger odd behavior with this combination, especially with the original EOSM (Mk1) camera which would literally freeze occasionally or generate excessive purple fringing etc. But by itself the lens is perfectly ideal on any model of EOSM. There is a huge thread on SGL discussing the Samyang 135. It contains images and tips on using it in a variety of ways: The Heart and Soul Nebula in Cassiopeia; with careful framing, it is also possible to fit the double cluster in Perseus into your view. Yesterday night I set all the equipment outside to do some (very poor) tests. Many things went wrong, as expected, but that was the goal, find out what's wrong. This includes power and cable management, drew protection, better wifi coverage and test software better (I installed NINA on the field 🙈 🤣). Now, I have to admit that up to this point, it sounds a little too good to be true. The downsides of this configuration are that shooting wide open can make focusing difficult.DSLR Cameras Canon EOS DSLR Cameras Nikon DSLR Cameras Digital Compact Cameras Instant and Single Use Cameras Instant Cameras Instant Camera Film Single Use Cameras Instant Printers Here is a worst case example showing meridional lines having very strong contrast running through the top left corner of an ultra-high resolution 5Ds R image (100% crop). So let’s take a look at close-up sharpness. I can’t see any significant difference between f/2.0 and f/5.6, maybe f/2.0 is even a tad sharper but this is not worth noting when it comes to performance in the field. You only stop this lens down when you need the depth of field, not to gain sharpness. The excellent close up performance hints that this lens could be turned into a great macro lens when using extension tubes. Even without them, the good maximum reproduction ratio of 1:4 lets you get pretty close to the subject.

If you want the best value possible for your money, and can survive without autofocus, buy the Samyang. If you must have autofocus, and care about weight, buy the Canon. If you want the best possible image quality, and you must have autofocus, and you don't care if it is a bit heavy (maybe you need it for studio use), buy the Sigma. Include the Carl Zeiss in your research though, it might be an interesting lens for you, even if it is a bit pricey for what you get. If you are a Nikon user, of course have a look at the Nikon AF Nikkor 135mm f/2D DC and compare it to the other lenses mentioned in this article.Film & Darkroom Film Clothing Instant Printers & Consumables Ink Jet Printing Canon Ink Jet Printers Ink jet paper Service Plans & More By f/4, with the Samyang's focus shift coming into stronger play, the Canon pulls ahead in the center of the frame performance (without making adjustments for the focus shift). Again, we see a super high-contrast situation wide open with sunlit branches at a distance of ~15m. No noticeable longitudinal or lateral chromatic aberrations, very impressive. Usually, a low until moderate amount of chromatic aberrations can be corrected easily during post-processing. In some situations, it can really ruin images. I was pretty sure that the last image would have been a firework of purple fringing with fine structures, not that easy to correct without loss of information.

To semi-automate taking this many images you will need an intervalometer that can connect to your camera. This handy gadget allows you to set your exposure length, the number of exposures, a short pause between each shot and allows you to be hands-free so you don’t have to keep pressing your camera’s shutter button. For the Nikon Z6 something like this https://amzn.to/3oIGrOS would probably be suitable, I have used a similar one successfully for my Canon 7D and 200D. This is a manual focus, manual aperture, manual exposure lens that does not report any information (not even the aperture used) to the camera. Resolution – at close distance the Samyang absolutely crushed the Canon wide open and remained better overall until diffraction became an issue. At a longer distance Samyang once again blew the Canon out of the water at large apertures.

Cons:

With no general agreement about what Bokeh is it is little wonder that there is so much argument and disagreement. Everyone assumes their definition is the "true" one. While the 135mm focal length is a bit long for use as a sole general purpose lens, it does have general purpose uses including for At f/2, images are very sharp in the center of the frame and incredibly sharp in extreme full frame corners. From the moment I reviewed the first sub-exposure on the display screen of my camera, I feel in love with the mid-range magnification of a 135mm lens. My first shot was a section of the constellation Sagittarius that included the Lagoon Nebula, and Trifid Nebula.
