At 200mm and beyond AF is a big deal, at 50mm it's not a big deal for me, and at 24mm it's half as important as that.

I really, really hope Sigma can produce a decent body to go along with their new lenses. Having a complete system with the Sigma name on it would put the company in an entirely new league.
Forget about being innovative, just match the specs of the 5D3 to a T and copy as much of the controls and menu as you can.

$1500 for 1" sensor :-\


Just like the Nikon V3!

At least the new Lytro actually produces images at a "useful" resolution. The resolution of the original really held it back.

Lenses / Re: Sigma 24mm F/1.4 Art lens is apparently in the works!

Sharpness is nice, but sharpness is not the top priority for that focal length.
I would be even more impressed with a distortion free 24mm lens than just a "sharp@f1.4" 24mm lens.

Of course, combining the two would really make waves.

Here's what I was looking for. Now we can just read that one again instead of making a new one.

I wouldn't call the difference in noise between the 1D IV and 70D a "wash". Compare the noise test results from DPR:

Why on God's green Earth would I compare RAW files with no NR when I never work that way and neither does anyone else?

If your photography consists of staring at zero NR, ISO 3200 black and gray patches at 100% until your eyes cross, buy a Nikon or a Sony. Then you can boost those RAW files +5 stops and really have some fun staring at patches.

I feel another RAW thread coming up.

and if anyone is wondering why people are so frustrated with waiting for the 7D2, look at the following graphic....it's already been a year longer then the next longest in production Canon digital camera and at least another half year to go...

and if you look at the cameras currently in production, it has been out for 5 years.... next oldest is the 1DX at a mere 2 1/2 years...

This is why I say that whatever is coming, it's going to be big!

BTW, Thanks Wikipedia for the graphic!

Ah, but this assumes that the 1DX truly is the successor to the 1DS MKIII.
Regardless of how they classify it, Canon will soon be approaching a full decade since they've upgraded the resolution of their full frame sensors.

Now if only Canon had these kind of deals on their lenses.  :'(
It isn't a Sigma deal. It's a LensRental deal. They paid $26,000 for the lens, rented it once for about $1000 and are selling it for $15,000. They lost at least $10,000 on the lens. Incidentally, they also sell used Canon equipment.

I seriously doubt they paid MSRP for it.

I used to think the 7DII might come pretty close to FF in IQ and high ISO performance. Until last November, when a thread in CR completely disillusioned me. Next thing, I bought a 5DIII and sold my 7D and I've been kicking myself ever since that I didn't do it a year sooner. So yeah, I totally see what Jrista is talking about [although not cool to use 'trounce' in APS-C vs FF (that too same generation), Jrista, not cool].
I am lucky that I didn't end up waiting for 7DII and be disappointed.

Agreed!

If IQ was my only concern, I could walk into the local bestbuy and grab a 6D for less than what we expect a 7D2 will go for. There is no way short of physics defying magic that the 7D2 will beat it... But for me, I really want a more capable AF system and after playing with the touchscreen interface on a 70D, would like to see the next generation of that too... Hmmmm...... 5D4?

It's clear that a crop sensor can match full frame IQ (I posted the 1DIV comparison for relation to the OP) in some circumstances, not many, but it is possible. We're going to need a lot more pixel density on our full frame cameras to go beyond that.

I think people aren't giving enough credit to the processor when talking about low light. It seems pretty clear to me that the biggest upgrade responsible for that 1 stop advantage in the Nikon D4s is the processor.
Sensorgen doesn't have the specs up for that body so I can't say if there has been a significant improvement in QE or not, but at least Nikon seems to advertise that the processor is a major factor. Of course then we have to decide how much we trust marketing.

I wonder if Canon Rumors just posts these deals as they find them or if they save them specifically for a rainy day.

I saw this last month, and it may have been up a lot longer. It's a similar pattern with some of the other "deals".


As for the Sigma itself, making this a zoom killed it for me. I'm guessing it would be great for people in a press box at a stadium, but out in the field I would rather have something half the weight that I can handhold.

It's unfortunate that the sensor size isn't even twice that of full frame, I have to wonder what it is that makes the body so much bigger when the sensor is only 10mm taller?
What's the buffer depth in RAW?

I guess it's a nice product for what it is, but I still don't see it being 3x better than a 5D3/D800.

Make the SL1 design mirrorless with a more solid body and your problems are solved. EF/EF-S lens compatibility and a form-factor that people are familiar with and like.

One up that, since it's mirrorless use the extra space to put a full frame sensor in the SL1 body.

The primary benefit of mirrorless for me is not size, it's being able to accurately manual focus at f1.4 with the viewfinder.

The reduced size is nice though.

I haven't heard anything particularly good about the Samyang Telescope lenses. Lots of people like some of the other telescopes (often Russian), but you're probably better off putting the money toward an SX50HS, which has some proven performance compared to modern supertelephoto lenses.

Pricewatch Deals / Re: Sigma 50mm f/1.4 Art Available for Preorder

Thanks, JD, and I just found another review of sorts:
http://fstoppers.com/sigma-50mm-art-review


I read that earlier... Now it just comes down to pulling the trigger.  I think the worst thing in the world is that Amazon had the 35 art for 699 last christmas... so if I wait long enough, I can get the 50 art for 749 new... and that's going to drive me nuts. 

But it is only taking a loss on the lens if I ever decide to sell it... and I'm thinking it is hear to stay just like may 70-200 mkii and my 100L... and it would be nice to have a wide open sharp lens that isn't too long.  The 85 was practically useless indoors, and 35 feels too wide open for me... so 50mm is the goldielocks slice of perfection...


I'm so glad to hear someone else pointing out that 50mm definitely has advantages over 85mm. Earlier I almost posted a rant about one of my (admittedly few) experiences trying to shoot 85mm indoors. Frustrating to say the least.

If more reviews come out like SLR Gear's, will Canon and Nikon step up their game or will they just admit defeat? Sigma is making it really difficult it even consider a 35mm or 50mm from another manufacturer.

I'm hoping Canon can do a 50mm f1.4 (or even f2) IS, that would be both something new and highly desirable.

They were smart. They knew they needed to keep it under the psychological $1000 threshold, so it seems like a bargain and it is clearly less than the OEM.  But OTOH, they had a ton of built-up demand so they wanted to get close to $1000.   Brilliantly done.

I have no problem with Sigma milking this lens, I'm sure they could use a cash cow right now and if it means they will be better able to produce more fantastic lenses like it then I'm all for it.
Once their sales figures as a whole look a little more like Canon then we can get picky about price.

Now we just need to see whether the images at the extreme ends are actually worth anything.
