Thanks for the advice.  I did some test shots on the roof of our apartment.  I've tested at aperture f2.8 and f5.6 while varying the focusing distance between beyond infinity up to 1 meter.  The photos are uploaded to Flickr.  There are no extra sharpening or adjustment; only what ever was done during exporting from LR4 to Flickr.  All photos are handheld.

Couple things I've noticed when looking at the apartment windows at the center of the picture:
- at f2.8, none of the pictures are sharp. 
- at f5.6, the sharpest is at 3m focusing distance
- at f4.0, the sharpest seems to be right at infinity mark but still not where as sharp as f5.6
- If I want to take stars at night, f2.8 could be a problem.  Should I continue to Now updated test at f4.0?
- How to I get sharper images at f2.8?  Is this possible?
- Am I doing something wrong?

I found a website that describes a solution to the focusing issue.

(emadeloc.blogspot.com.es/2013/01/brico-como-calibrar-el-enfoque-de-un.html)

I would assume most of the 14mm users in this forum have seen or even used this fix.  Has anyone try to fix the lens themselves?  I would like to hear your feedback.

What are your thoughts if I try this fix myself.  Does it look like I need it?  It seems easy enough even for an amateur like myself.

----------------------------------------------------------
BTW, a colleague of my contacted Samyang Optics directly regarding the changes from the gold to red ring.  Here is there reply:
문의하신 14mm F2.8 렌즈는 Gold ring에서 Red ring으로 바뀌었으며 렌즈 성능에서는 동일합니다.
(단지 외관에서 Gold ring ==> Red ring으로 변경되었습니다.)

...Google translates
Gold ring 14mm F2.8 lenses, contact your Red ring of the lens performance, the revised and the same.
(Just look at Gold ring ==> Red ring has been changed.)

Basically, the new Samyang 14mm changed from gold ring to red ring and the function is same.
----------------------------------------------------------


Mine seems quite acceptable at f/2.8, it could be just the slightly shallow dof is making things around the focal point look soft?

You know, you can create quite a shallow dof even at 14mm, I was kinda surprised. Here's a rejected shot that was basically just a test of f/2.8 the candle in front is in focus and quite sharp too. no sharpening applied in post other than the standard LR amount.

I pretty much shot the entire day at f/8 which I reckon is around the sweet spot for mine. With a little PP files look very nice indeed. I wouldn't really recommend using it f/2.8 unless you really have to.

Here's a better one than the last one. Can't leave it like that!

I haven't tried to fix anything on mine.  I have just familiarized myself with where focus is for different applications, and my keeper rate is basically 100%.  My copy is sharp from wide open - you just need to be more careful with focus.  Live view is the best bet with wider aperture.

Thanks again for the advice from everyone.  Do you think I have a bad copy or it's just I haven't found the 'sweet spot' yet?  It seems like there is very little room for error when shooting wide open, maybe just a mm turn on the focus ring is enough.  I guess I need to play with it more and try smaller increments to get the right sharpness near and far.

BTW, I always enjoy looking at your photos.

To be honest, at the size that the photos are on Flickr, I thought they looked fine.  If you feel like you don't have a good copy, I would exchange it.  The time to do that is when the lens is new!

Just to add to the collection, I recently completed a review of the Samyang branded version of the 14mm

Surprisingly good for the money, if you can live with its foibles

Hope it adds some info of interest ;-)

I just read the review.  It is very well done, and your conclusions are very similar to my own.  Unlike me, however, you were able to directly compare it to the 14L, and I found that very helpful.  Thanks for sharing!

Here's a Christmas themed image, and another example of why the Rokinon is such a great choice for shooting at night.  (And yes, the "Bethlehem Star" was added in post, but the rest of the scene is a single exposure.
