Thanks for starting this one, been meaning to look into it as well.  I was going to just look into what WHCC offers.  http://www.whcc.com/products/books-albums/press-printed-albums

your samyang 14mm hard stops at infinity? I had read that they did, but figured it an error as mine seems to roll right on past infinity.

Well no, not exactly.  It was doing that after it was very cold is all.

Several more now on this page from the other night.  http://www.extremeinstability.com/2012-12-21.htm

This whole idea and op was a little involved lol.

Yeah that is what I feared when I first used the hard stop on this Zeiss 21 and it being the first hard stop lens I've owned.  I thought, how does that work when it gets cold unless it happens to change the other direction and hard stop is in normal temps.  Seems the change usually is towards the past infinity direction though.  But the other night I used it without problems it was about 15F out I guess.  Then again now that I think about it, I was mostly using the Samyang 14.  It's focus seemed to change so far that it was pretty much hard stop well past the infinity line on there.  I should just leave the Zeiss out one of these 0F mornings coming up and see if it changes much from the hard stop.

Not exactly portrait but since I wound up in the shot I guess it works.  From last night.  Winter boredom resulted in getting the idea to drag a car battery and an inverter, with some christmas lights and well....

Awesome photo!

extremeinstability, fantastic picture! What duration did you shoot for?

Thanks.  Well I'll be making an account of images today hopefully and try and explain in there.  Basically for the stars it was 20 second shots, F2.8 at 640 ISO with the Samyang 14 on a 5D II.  The camera never moves for the Christmas lights shot or the lantern shot.  The Christmas lights at that setting needed turned on for like 1 second tops then turned back off.  Easy enough to get the images for the star trail stack and then do one with the Christmas lights turned on then back off real fast.  Then without moving the camera still I'd do a bunch of lantern poses so I can just use which ever one of those later I want.  Those were with different settings.  I could leave the ISO at 640 and do those at like 2-4 seconds.  The only tricky part then is just stacking in the lantern frames as they are a lot darker and using "lighten" blend mode like the stars and christmas lights, well doesn't work.  So just used normal mode and had to mask it right.  Then adjust a curve on that and the other one so it balances better.

Lenses / Infinity and Cold
« on: December 22, 2012, 01:57:51 PM »
After getting a 21mm Zeiss that has a hard stop for infinity that is spot on too, I'm wondering how that still works with bitter temps.  Seems most of the lenses I've had the infinity changes a good bit if the lens gets really cold.  Last night for example the infinity on the Samyang 14mm seemed to be clear at the very edge, while warmer times it seemed it was definitely on the other side of the infinity line.  Guess I'm not sure what I'm wondering exactly.  Just what others have seen.  Some lenses must be designed differently that it's not as big of an issue.  First impressions is that it's not budging on the Zeiss.

I've only had problems with my push pull 100-400L, granted I've never owned a huge collection of lenses.  It for sure is a dust pump.  Looks like it was assembled in the Sahara desert. 

I've had it fog up inside the same area as well.  The only way I got it back out(without waiting forever) at the time was to blast the car heater on the lens then push pull pump it a lot, then cool it back down in the cold outside air, then repeat.  The expanding and contracting along with the pumping eventually dried it out.  Had to dry the car out from all the snow melt issues first. 

Seems the vacuuming stays out of the cam.

I wonder if there is anything wider than 50 and probably really wider than 35mm too that is faster than F2.8 and doesn't have much coma full frame edges/corners. 

I'm tempted to try the Samyang 24 F1.4 for the night sky lens when stars are part of the subject. 



Sure otherwise the Canon is better but for stars I'd think the Samyang would be better even if wide open it  has less resolution.  If I ever have $600 laying around and a lens buying bug again I'd probably have to go with that.  I really missed the wide faster than F2.8 deal the other night on the meteor shower.  50mm worked ok enough full frame and well 35 F1.4 would have probably been ideal for just that.  But yeah big sky 24mm would be the end of the least wide.

The Samyang 14 really turned out to work well at night.  I had my doubts because of the large vignetting wide open, but really it turned out to be ok.  http://www.extremeinstability.com/2012-12-1.htm  Some night stuff on there with both the Zeiss and the Samyang but not star fields.  The fogbows would not have fit without the 14.  Brief trip with the 24L II at night before I swapped it for a Zeiss 21.  http://www.extremeinstability.com/2012-9-22.htm  Really was pointless to get that one for night over the Zeiss since even F2 coma was nasty anyway.  There was very little improvement.  Least F2.8 is fast enough for most things anyway.  But yeah the meteor deal, F2 felt like a huge improvement over F2.8.  Sure some was 50mm compared to 21mm on them too but it just felt larger than simply F2 to F2.8.

Zeiss 21mm might be my fave now.  The Canon 24L II proved pretty pointless for night sky more open than F2.8 anyway.  Coma extends well into the photo, bad coma, so it tends to make it a little pointless for that added F1.4 to F2.8 range it would allow at night.  Unless one likes big ol wings off their stars I guess.  Samyang 24 F1.4 had less coma and might be interesting.  Canon 14L had plenty of that too.

I think most larger companies wanting images and often purchasing images, kind of fear not paying someone.  Say someone snags a photo off my website and posts it on instagram/etc and they get it that way.  So then I send them(end user) a nice bill or let a lawyer do it as the images are registered.  At least if they are paying someone, they should have a better recourse if someone does that.  Because I sure won't care if they can't then find whoever snagged the image.  So many times I've been told "well a friend of blah said we could use these images."  Great, like I care what someone fed you.  Seems plenty out there learn it is better to be paying someone something.  Course I laugh inside knowing the crazy amount that don't and think it is cool to just snag and use. The amount of people that will snag any and everything off the net and "share it" in their own folder on these sites, I don't get how many companies are going to feel real great taking free images from these same places.  They are at least less protected going that route. 

Is it me or do I not see samyang under this list when searching for it?



Adobe lists the lens under samyang , but it's all the same

For those using Adobe I got mine here:  http://www.adobe.com/support/download/destail.jsp?ftpID=5492
Download the adobe lens profile downloader.    In there change Camera make to Canon then under lens it is way down the list at the bottom listed as samyang.  Then in the raw converter it's under Canon. 

I'm pretty happy with my 4 lenses on a 5D II.

Samyang 14 F2.8
Zeiss 21 F2.8
Sigma 50 F1.4
Canon 100-400L

Would add.
Canon 24-70L II(I think)

Thoughts on them.  I don't think I'd even care to swap the Samyang 14 for the Canon 14 if someone wanted to.  Loving the thing and I've used a Canon 14L II before.  The Zeiss 21 is really just sick and not going anywhere.  I would likely swap out the Sigma 50 for the Zeiss 50 F2.  I suppose swapping out the 100-400 for the 200-400L would make sense too.  Would then need some mid-range zoom and the 24-70L II would work great.  Yeah that'd be a damn happy full frame line-up.

Used a 5D II a couple times in -25F for a while without issue.  Left it out shooting a star trail basically all night at 0F.  Only problems were getting frost caked on things and the LCD playing images really really slow.

May wind up wishing you could trade back for this only 7 hot pixel one.  7 sounds great lol.
