Lenses / Re: DXOMark: Sigma 24-105 f/4 DG OS Reviewed

isn't 2014 supposed to be a big year for Sigma?  isn't there a rumor that sigma might be releasing a new camera this year?  is it possible that this might be the kit lens for that camera?

I don't care if it has video or not.  I think the real story here is going to be the form factor and ergonomics. I've been trying to figure out why we haven't seen a smaller form factor full frame.  I just wish it would have been an Olympus.

6D is two stops better or so.  So if 800 is your cut-off now, 3200 would probably be your cut-off on the 6D. Anyone else agree?

Always shoot raw.  I always print directly from lightroom.  For web I export at 96ppi because it's my understanding that that's a pretty standard ballpark pixel density for modern computer screens.  I usually export with the short edge at some multiple of that, usually 576  or 672.  That gives a good sized image for social media. I also export at 100% quality, because if you upload to a site that does it's own compression of your image, it comes out better when they're done with it (you're not multiplying compression artifacts).

I haven't used my Canon printer (it was a pretty cheap one)for a while, so I can't speak directly to Canons, but I know with Epson, when you go to print there are options about color management.  You have to make sure the printer is set not to do any color management, so that LR can manage everything.  I always print with perceptual intent, an appropriate ICC profile loaded, and color management on the printer turned off.  If you don't turn the color management on the printer off, it doesn't come out right. You may already know that, so hopefully i'm not wasting your time.  I thought it might be a good thing to check, though,  if you hadn't thought to yet.

Canon cameras have a relatively short sensor to flange distance, so there are tons of old lenses that can be adapted.  There is a whole section on on alt lenses.  There are also flickr groups as well as forums dedicated to manual focus.  You should be able to find lots of opinions and sample pictures out there.  Contax/Zeiss lenses are popular as well as Leica R.  These aren't really budget though (generally speaking).  I really  like the Olympus OM series lenses.  They are tiny, light and have pretty decent quality.  A lot of them can be found under $100.  The ones with better reputations can be a little more expensive.  I've been able to get ahold of a lot of the Olympus OM f/2 lenses for around $200, and they make pretty nice pictures.  Also, it's my understanding that with video, since you're recording at a resolution of 1920x1080, sharpness isn't such a big deal.  The samyangs are pretty nice too.  I have the 35, and it takes great pictures. It's huge though.

I really enjoy the olympus lenses adapted to canon EOS.  They have no issues with mirror clearance on the 5D line.  The 35mm focal length is kind of a week one for the system though.  If money's not an issue though, and you want something nice, I would buy something new and modern.   I play with the olympus lenses because they are pretty good and relatively affordable.  If I sold all of my olympus primes I might be able to afford an L prime.  Nothing's nicer than the new 35mm primes, if you're willing to pay for it.

The Gaudi stuff is pretty touristy, but makes for some good photo ops. Also, If you happen to be there for a riot, that helps too.

Ok. I couldn't help myself.  A couple more.

I love this little lens. Not the sharpest tool in the shed.  But nice and small and light.  Perfect on a crop.

Canon General / Re: Selling question...

Going rate seems to be about $1300 on the ebays.  If you ebay, I would start the bidding at $1300 minus the cost of a shutter replacement and then let the market do its thing.  Things often sell for more than they're worth on the ebays(lots of impulsive and uninformed buyers, plus there's a gambling and winning aspect to it), so it would probably work out pretty well for you.  I think it's your best bet for maximum return. Otherwise, I still think you could pick up at least a grand, probably a little more selling in craigslist or in forums somewhere.

Ooooh, Ooooh! I want to get in the fight!

From my personal experience, the 5D has better image quality than my T2i(which has the same sensor as a 7D), especially at higher ISOs.  Also, I don't think anyone should be shooting either sensor at higher than 1600, because they both look like uber crap beyond that.

The 5D and 7D have similar noise levels, but the 5D is ever so slightly better, and for some reason seems to retain more detail.  The noise has a different character.

As far as it being quantifiable, when I look at comparisons online, they all seem to agree with the above, so I'm not sure where dtaylor is getting his info.

Check out DxO marks comparison.  I know their overall ratings are meaningless, because no one can figure how on God's green earth they justify the weighting, but I think their testing is consistent for the individual tests and therefore, acceptable for comparison.

The 5D only loses in the dynamic range department at low ISO.  And it's better than the 7D at ISO 800 and up.

Have a nice day everyone.

Lenses / Re: Budget wide-angle for FF

Isn't there a difference in which way the focus ring rotates on the samyang and the rokinon, or something like that? The rokinon turn direction matches canon and the samyang matches nikon? 

If you're looking for good lenses on a budget, and you're willing to do manual focus, I would highly recommend looking at used Olympus OM-system lenses.  Since they're legacy, sometimes they need a little work, but they have outstanding optics, build and functionality. All it takes is a simple metal adapter that will cost you around $10. 

I would suggest the Olympus OM H.Zuiko Auto-W 24mm f/2.8. You can find a copy on ebay for around $125.  If you're lucky, significantly less. 

Half the beauty of canon cameras is that they have a short flange distance that makes it possible to adapt a wide variety of lenses. Once you start looking beyond the canon lineup there's a world of possibilities.

Lenses / Re: EF 24-70 f/4L IS & EF 35 f/2 IS

Why are people dissing on the 35 f/2 IS USM? This is the lens I have wished for the most.  An updated 35 f/2. I really like my 35 f/2 and it is my most used lens on APS-C.  The focal length is great and the image quality is stellar for the price.  It's only real downsides were the noise and the poor full frame corner performance. I use mine on my 5d by the way, and i don't hate it, but it could definately use some improvement.  Hopefully these are the things that are fixed. 

As far as it being only a stop faster than the 17-55, f2.8 doesn't cut it for low light, no flash on APS-C when people are involved.  That extra stop makes a world of difference.

It will probably rival the L in everything but the extra stop.  The L will probably retain only slightly higher center sharpness.   

It was kind of ridiculous for canon not to have a good modern consumer prime in the 35mm focal length.  I'm glad they finally got around to upgrading. Hope the prices aren't too ridiculous. Hopefully that new sigma will give it a run and bring the prices down. I was really excited about it until this announcement.

I'll wait for the data though, and then probably until canon knocks $150 off the price like they did on the 24 and 28, before I buy it.

Oh, and I forgot to mention that the consumer 35 is a hell of a lot more discreet than the L.

« on: October 04, 2012, 04:57:29 PM »
The U2711 is a wide gamut monitor, right? That means you need a video card that is capable of doing 10 bit color if you want to get the most out of it.  You'll have to get a professional card (like the ones made for CAD), either an Nvidia quadro or ATI Firepro.  I've also read that the consumer Nvidia  cards will do it, but I don't have any personal experience with them and I've only seen it a couple places.   I know the comercial ATI cards won't do 10 bit color.  It's stupid because they are more than capable, they're just crippled so that they can't.
