Third Party Lenses (Sigma, Tamron, etc.) / Re: Sigma 35mm f/1.4 DG HSM
« on: December 26, 2013, 02:25:57 PM »
I just got is lens, opened it 2 days before Christmas.  I am blown away.  It is sharp sharp, and lots of good contrast and color. I really like the 35mm field of view too; a lot more than I even thought I would.

Made one dummy error though. I was doing the post processing on my kids opening the gifts from Santa and I noticed some hellacious vignetting in top right and lower left. I was thinking I'd made a big mistake, and thinking how I might have trouble returning it because I got it grey market for $760. Then I thought about the lens hood. Sure enough I had not screwed it on all the way, and the longer petals were on those 2 corners, and not on the top and bottom like they are supposed to be. Problem solved. Duh.

Lens Comparison: Sigma 35mm f/1.4 "Art" vs. Canon 35mm f/1.4L USM Small | Large


Here's a reviewer who makes the comparison and likes the sigma better in: 1.) sharpness, both in center and at edges, 2.) CR/fringing, and 3.) Bokeh.  He says the AF is a tie, which in practice sometimes was actually won by the Sigma.  Lots of images.

So it would be a mirrorless camera?

Perhaps people in the know are clearing these out, to get ready for a new Sig 50 ART lens?

There's lots to improve on the 135L. If all Sigma did was improve corner performance wide open I would be happy. A shorter MFD would be nice too.


Big DSLR announcement, hmmmm. Could they make a camera with an EF mount? Just think, all the sigma lenses sold to canon users would now work on it along with the canon lenses too, it would be a Trojan horse coup d'e'tat

Interesting, but they'd need to ditch the Foveon sensor and go regular. Too large a data file not to have any real improvement in resolution, at least not that ive read anywhere outside the Sigma website.  Or maybe  non-Bayer like Fuji's x-trans. That would be exciting indeed.

What if Sigma made a Canon EF mount camera with a Sony sensor. So-sigma?  Sig-ony?  Sig-can-nony?

I'd rather see them to with the non-Bayer design though.

I think part of the whole reason their Foveon camera didn't take off was that it was a crop sensor. Originally they were asking 1D prices for an APS-C camera, that just doesn't fly.
If they can put out a 20MP full frame Foveon sensor (60MP counting individual sub pixels), upgrade the autofocus, make sure it has lots of dials and price it to compete with the D800, I think they would have a winner.

I'd welcome the competition. Price would have to come down, but FPS and buffer depth would need to come up. Not sure how much Sigma can do about that given those huge files.  Their latest body was a little weak on that department. Is the blockage there the card's speed or their processor speed?

I don't understand this tip.  "No 7d coming - a friend."  Does the cryptic "a friend" imply this was an anonymous tip?  If so, why is it credible enough to print?  But if it wasn't anonymous, why was it signed with "A friend"?  ???

Perhaps printing this rumor may flush out a solid tip from some other sources who were not saying anything before, but who want to clarify or repudiate this tip.

I really don't care if they make a metal body. I don't use my camera to smash walnuts or to bludgeon Nikon users.

But they do need to make something a little larger than Rebels or 70d"s, and with a great AF system. Seriously, how much can it cost to go ahead and give the thing 40+ AF points, with most or all being cross-type?  If they no longer need to hold back to create space between 70d and 7d2, they could make 80d (or a new line) that has as many AF points as they want.

But the power reductions on the transmitter combine with the cuts on the receiving flash to reduce the output on the receiving flash. So if I have the receiving flash set at 1/1 power on the unit, and then I lower power to its group (a,b or c) on the transmitter to say 1/4, it shoots at 1/4.  But if I set the unit at 1/4 and reduce its group to 1/8 on the transmitter, the power emitted is 1/32.

So a single unit lets you knock 7 stops off of full power (1/128 is the lowest power setting). But if you fire the flash set at 1/128 on the unit itself, and the transmitter is also set to 1/128, you get a flash of 1/16,384 power, which is (I think) a 14 stop reduction.   Or more practical, you could have one on 1/2 and the other on 1/128 for a more usable 1/256 power.

Correct?

I have recently purchased three Phottix Mitros+ flash units. I have been playing around with them, and a couple of light stands and shoot through umbrellas.

The manual says that the power cuts on the transmitter and on the receiver are "cumulative" to each other.  This definitely proves true in my experiments with them so far.

Does this mean that I am basically getting a lot more low-power settings using two units than you could get using just a single unit on camera which would bottom out at 1/128?  I Have noticed that sometimes 1/128th power is too much up close. So does using a wireless flash like this really extend the low-power capability of the flash in the way that the math seems to suggest?  If so, that is a serious extra benefit to having the two units and the wireless connection.

And the Mitros+ lets you control the flash's telephoto zooms from 24-105 remotely.

I got 3 of them delivered last week. They are really heavy and solid.  It has been raining and I have been working kind of crazy hours so I have not had time to play with them much yet.

Sweet shot Neuro, really nice bw convertion.

Thanks, Viggo!  I was in Philadelphia a couple of weeks ago, took the opportunity to walk through the Eastern State Penitentiary - pretty cool place, and the photos just beg to be converted to B&W...

Yes, a very nice shot.  I went there several years ago, when I had a Canon super zoom camera, and I somehow left it in the cab when we got back, and someone stole it. I am glad, as it prompted me to get a better camera, but I did lose all the images I made there.

Interesting note to those who haven't been:  this was where they shot the insane asylum scenes in the movie "12 Monkeys" with Brad Pitt, Bruce Willis.  They reprinted one "spoke" in the wheel design there and did some serious dusting.

Sorry but the world's best DSLR lens would have AF....

Although I love my AF more than anyone, I have never experienced a MF lens jump to background or hunt.

Sure, but you can turn AF off whenever you want to. But not having the option for AF is a negative. Remember that their "world's best" claim was bold, and broad, and kind of outrageous.  But the WORLD'S BEST DSLR LENS would be able to do something as simple as autofocus.  When people discuss Bower or Samyang lenses or other cheap-o brands, no one bends over backwards to dismiss the shortcoming, unless it is to say that is forgivable "for the cheap price", which does not apply here with the Zeiss.  So a great lens?  Sure.  The world's best?  That is really bold.
