p.1 #1 · Nikon 85 1.8G vs Samyang 85 1.4


I know the Nikon 1.8G is fairly new but has anyone done any comparison with it against the Samyang 1.4? I'm more interested with the sharpness and bokeh but no so much on the built. I have a D300s.

Have you looked at the photozone tests?

http://www.photozone.de/nikon_ff/717-nikkorafs8518ff

http://www.photozone.de/nikon_ff/605-sigma8514ff

Done on full-frame, but they should give you an idea of the relative performance.

Hmm, I was thinking more of Samyang and not the Sigma but thanks for the 1.8G link.

The Nikons, Sigma, and Samyang are all close in sharpness and bokeh wide open. The 1.4 will have a slight edge in bokeh. The main differences would be price and focus. The Samyang is manual focus. The Sigma focus the fastest. The Nikons the slowest.

The difference between f/1.4 and f/1.8 is about half a stop. Is the 1/2 stop important enough to get a manual focus lens like the Samyang or a much more expensive lens like the Sigma? It's your money so only you can answer that.

Sorry,

I was trying to link that while getting the kids ready for school. Looks like only the Samyang 35mm was tested on the Nikon platform. On the same site they have tested the Samyang 85mm on Canon - not a direct comparison but may be somewhat helpful.

I own the Canon mount version of this lens and recently sold the Nikon mount. Both copies are/were fantastic; in terms of sharpness and bokeh. For the price this lens is a "no brainer", that is if you don't mind the MF. Bear in mind that having a good focusing screen will be a must for the the 85mm and MF. I had to replace my focus screen on the 5DII and now I am able to take crisp shots ~90% of the time at f/1.4. Both of my copies have/had a rather stiff focus ring, and that is my only complaint with this lens. I am still astonished as the image quality achievable from such a moderately priced lens. After my positive experience I have also purchased the Samyang 35mm and it too performs beyond my expectations.

If you guys think the Sigma is the fastest focusing lens out of those you are crazy.
The 1.8G is lightning fast.
The sigma is nice but at 500$ the weather sealed 1.8G is the best bet hands down.

The difference between f/1.4 and f/1.8 is exactly 2/3rds of a stop.

...and that can be a big deal depending on the light.

I am more concerned with the depth of field and bokeh differences than I am with the 2/3rds stop less light.

I too come from a film background and Kodachrome 64 was my film of choice. The current Nikon digital cameras are so much better than what I had in film that I don't have to worry about 2/3rds of a stop difference.

If adaptability floats your boat (mirrorless, Canon mount,....) the Samyang gives you aperture ring. You can also have Nikon G-lens adapters with aperture control but is not the same (at least the cheap ones I have used).

Also, I dont know how the focusing ring of the 1.8G is, but if you are into using the camera for movies, the focusing ring of the Samyang might be better.

Still, if I had to choose one lens today, I would go with the Nikon 1.8G

IQ on my samyamg is top notch. MF is somewhat cumbersome as I am just spoiled. I can't believe I used to manual focus everything. But for bokeh and sharpness, wow!

I had the Samyang for awhile. I really enjoyed it. The optics were excellent, and the results were stunning. The focus in my copy was a bit too damped for my liking and fast focus adjustment wasn't possible. I sold it to fund some other ventures, but I could see myself buying another copy at some point.

An 85/1.4 mounted on an SLR just feels right.

Yes it can be. I was just asking the OP if, for him/her it was worth the trade off of getting a MF lens or a much more expensive lens. To some people it is and to some it isn't. It's a personal choice.

Yes the difference between f/1.4 and f/1.8 is exactly 2/3 of a stop. I said it was a little more than 1/2 a stop. Since 2/3 is exactly 1/6 more than 1/2 I'd say that qualifies as a little more.

Huh? Feel like I just read an excerpt from Finnegans Wake.

If someone tells me how I should test the lenses against each other, I will do what I can. I bought trenchmonkey's Rokinon 85mm f/1.4 in February and will shoot with the 85mm f/1.8G for the first time tonight.

You said "about half a stop", not "a little more than 1/2 a stop". "About" could be a little more or a little less. Then you said "Is the 1/2 stop...".

Why not just use "2/3rds of a stop"? My guess is you did not know. Now you do....

Actually I've know it for the last 45 years. I learned it in 1967 when I got my first SLR, a Canon FX with a 50mm f/1.4 lens. Next time the topic comes up I'll be sure to say 2/3 of a stop instead of about 1/2 a stop. I don't want to mislead anyone.
