Yes, very true about the CA, luckily I've been able to fix those issues in my shots so far, but one day.. you never know!

Automatic fixing in ACR just didn't work for me - a lot of manual labor in PS was the result.

To show how easy it is w/ the Samyang I did a quick comparison here - done in seconds automatically in ACR w/ my default Samyang 85mm profile. Note especially the mannequin's heads and the neon signs (click pict for hires):

And looking at sample images, the bokeh is very nice on the Samyang.

The bokeh this lens produces is just a dream

Thanks for the info. Might pick one up and sell either one when I've decided which one I like the most

Good idea :-) Sometimes you can get them brand new and very cheap on eBay from people who can't handle the manual focusing - that's how I got mine *g*

cheers all!

I have the 85 1.8 too, but you're telling me you sold that in favor of this? Very interesting! Was a 0.4 f-stop worth more than AF? Or what else do you find that makes the Samyang preferable to the Canon?

Indeed I did, for various reasons:
- I prefer the rendering and bokeh of the Samyang
- I hated the EF's CA (same w/ the 1.2L, btw) - mostly heavy purple fringing which was near impossible to remove in ACR, so mostly I had to do it manually in PS
- actually 1.8 to 1.4 is 2/3 stops
- I don't really need AF - I work w/ lots of vintage manual lenses anyway...

cheers all!

> I have this lens and absolutely love it.  It gives such a nice effect, and holds such nice colours for such a reasonable priced piece of glass.
No question! I even sold my EF 85mm ƒ/1.8 

> does adding the chip have any influence on the camera while manually focusing for video?
Not that I'm aware of - why should it?

> A frame pulled from 23.976 RAW video from the 50D on this lens at 1.4  No editing at all yet and I love the look
absolutely great!

Here are two shots from y'day evening - impossible w/o chip & ML trap focus:





cheers all!

I own a walimex (German distributor) branded Samyang 85mm ƒ/1.4 Aspherical IF UMC

A lot of people complain in frustration about focusing this lens and without any provisions it's really hard to focus @ƒ/1.4 because of the extremely thin DOF it produces. So I did a few things which brought my success rate to around 95% (the remaining 5% are low contrast situations):

- I glued on an EMF chip for camera feedback

- I select the desired focus point manually - I have focus point selection programmed to the thumbwheel on my 60D

- in ML I switched on trap focus on shutter half press

For some strange reason the last one really does the trick - there seems to be a difference between manually pressing the shutter button and having ML do it automatically - I guess it's the time difference from the moment the camera aquires focus. ML trap focus brought my success rate from around 70% (even with focus confirmation!) to 95%!

Examples with very thin DOF:
















here is a flickr set with a lot more pictures - all wide open w/ ML trap focus...


Thanks to the whole ML team for a really great product!

cheers and have a good time, all!

That would really be a great feature for all of us crazies w/ a bunch of vintage M42 glass :-)
