Lenses / Re: Prime vs zoom for landscape?

It looks like the main consensus is zoom, but I like the idea of having both!

It finally snowed here in New York City. Here are a couple of shots of Forest Hills, Queens.

I've sold and bought stuff for $400 or less on CL. I wouldn't mind purchasing on CL for things that are $500 or less. But when prices are north of there, I'd rather go to the Canon Refurb store or a more reputable place like BH or Adorama. Those places at least test and inspect their used equipment. Plus, there's the option of returning an item if it doesn't fit the description.

Lenses / Prime vs zoom for landscape?
« on: January 23, 2015, 04:19:57 PM »
What do you guys prefer? The IQ of a prime is hard to beat, but the flexibility of a zoom seems more practical, especially since it's harder to zoom in and out w/ just your feet in the wilderness. Is the IQ of a wideangle prime worth it vs the flexibility of a wideangle zoom?

Lenses / Re: Where are the new Canon 50mm and 85mm lenses?
« on: January 22, 2015, 12:53:39 PM »

Yeah. It took me 3 copies of the 35A to finally get a good one. But even if I was willing to go through that again with the 50A (I'm not; I'd rather spend my limited time taking pictures.) I don't think I would because of the size/weight.

Why is this lens so big and heavy, by the way? Pentax and other lens manufacturers have shown it's possible to make compact lenses with very good IQ. I don't know anything about lens design, so forgive my ignorance.

Sigma did not use a double-Gauss lens design, which is typical of 50mm lenses. They instead used a design like the Otus. I'm no expert on the topic, but I got the info from here:
http://www.lensrentals.com/blog/2014/04/yet-another-sigma-50mm-art-post

There's a lot of work/time/money that you have to sacrifice for the IQ of the Art. You have to AFMA, pay for and figure out the USB dock, and test out constantly just to find out if you have a good copy, which you may not and then you have to go thru the process again w/ another one. It's sort of like a very expensive lottery.

In the end, you'll be wasting time figuring this all out instead of just enjoying taking pictures. Perhaps for a professional, the Sigma is worth the trouble. But for a hobbyist, IMO, it's not.

I guess going back to the topic, I'll wait for Canon to update the 50mm.

OP here. I have an update, for whatever it's worth. Went ahead and purchased the 50A from B&H. Not surprisingly, it has AF issues. It was front-focusing right out of the box, and I used Reikan Focal to adjust it at 4 different shooting distances and then configured using the Sigma dock. Adjustments were + 15, +15, +17, +18. It's better now, but it is still inconsistent and erratic in ways that can't be fixed with calibration. (Note: I do use non-center AF points on my 5DIII quite a bit, so perhaps this is part of the problem. I've found that Sigma lenses don't always play well with non-center points.)

But even if the AF was perfect, I would still consider returning it, and here's why: the thing is big and heavy. It feels much heavier than the 35A, which I don't mind so much. But given that my two main lenses are the 24-70 II and 70-200 IS, I really want the 50mm to be lightweight and more compact.

I've owned both the 50L and the 50/1.4. I must have had a great copy of the 50/1.4, because I just went back and looked through my LR catalog and found that I had almost as many great keepers from the 1.4 as from the L. And my copy of the 50/1.4 was fairly sharp even wide open. I now find myself wishing I hadn't sold it.

I'm going to return the 50A and either get another 50/1.4, or just stick with the 35A and wait to see what Canon comes out with. I'm not in a huge hurry and can live without a 50mm prime, since the 24-70 II is such a phenomenal lens.

I've been contemplating the 50A for a while now and am also a Canon 50 1.4 owner. I think I can finally put the GAS to rest about this and will keep the Canon version.

Seriously, these are awesome! Thanks for sharing and great work!

Mmm exciting! although ive read that it weights a ton, finally a focal range and aperture that i need! :) let's hope iq and af are up to standards

You're right, this thing weighs 38.8 oz / 1100g! That's 50% MORE than the Sigma 50mm 1.4 Art, which is already very heavy. Plus, no filter threads, which could be a dealbreaker for folks.

I'm excited to hear about its performance! Yes, a few good UWA options are out there now for Canon. Versus the 16-35 f4L, I'm interested to see how it compares. I could sell a few lenses off and replace it w/ this one if it's that good.

Third Party Manufacturers / Re: Sigma 24-105 f/4 DG OS Discontinued

Although a bit better than the Canon L lens (slightly sharper and better contrast), it is also much heavier, and more expensive. So it is a tough sell, unlike some other 3rd party offerings like the Tamron 24-70 with VC. It also had some issues like lockups with the 6D if GPS was enabled, that took them almost a year to resolve. WOrse: to fix it you either need to spend a further $100 for the USB dock, or send it in for support.

On the Nikon bodies they had an edge in price over the 24-120 and in image quality, but ran into two other issues: the lens is a massive battery drain since it switches on the camera's metering for each shot and locks it on for 60 seconds. This was already true of the D800 bodies, and persists with the D600s and D750. This issue was never resolved. Users in events and other reported as much as 1% battery drain per minute.

It's definitely interesting to hear about the Sigma's performance for other brands! Thanks for that info. Those are some pretty serious issues and it makes even more sense for Sigma to discontinue the lens. I'm surprised that people would still use this lens, esp the Nikonites.

Wow! I guess the price just wasn't right for this one, esp since it wasn't weather-sealed and wasn't that much better optically vs the Canon version. I wonder how many are actually out there.

EOS Bodies / Re: Canon EOS Rebel 750D Spec List [CR1]
« on: January 21, 2015, 10:19:11 AM »
Actually, the Rebel line already has more cross-type AF points than the 6D, so I guess it's expected to have more already. 19 on the Rebel vs 1 on the 6D is pretty silly though. This makes the 6D even more obviously targeted to landscape and still subjects vs action at all.

Anyway, I agree that mirrorless cameras are getting larger. It's probably due to the fact that small cameras are just not ergonomic at all. In a funny way, the same thing is happening to smart phones. They became small and then just keep on getting bigger because people want more and more. Eventually, there'll be a medium where the size of a camera (and smartphone) will become the "best-selling" size.

Going back to the Rebel, I think it will have Dual Pixel AF. I agree that there's no reason for it to not have it as it should become the standard for Canon's APS-C. To distinguish itself to the 70D, I think it will still be smaller even w/ the rear dial. Consumers will have to decide which size/ergonomics/build-quality/performance they prefer, but IQ will essentially be the same. This is the same recipe they used for the 60D and Rebel line.

Way more cross-type AF points and MP than the 6D. Lol
