Lenses / Re: how to get 300 2.8

I wouldn't waste my money on Sigma. I would definitely choose Canon 300 2.8.

Why isnt this a "L" Lens?

It has all the bells and whistles of L series, but the ring is green not red, that's all :)

Canon tried painting a red ring over the green one, but it came out black.  They tried painting the red ring next to the green one, but decided people might only buy it at Christmas.  So they just stuck with the green ring.
Plus, green means go on contrary to red which means stop. OK, this is how a blond related joke ends.
I'd rather not say it complete though  :)

Looking at 7D II specs, I can't wait to see rumors 5D4 & 1DX II from Mr. CR

+1... Btw, too early for 6DMK2?
Too early. But someone will mention it. This is a rumors site after all. Since 7DII is a fact another rumor must appear  :)

it will have:

* no wifi
* no touchscreen
* no 4K video
* 24 MP DPAF 2 sensor with enhanced microlenses
* DIGIC 7
* 81 cross point AF system
* x-sync 1/200s
* ethernet
* usb 3

that´s all my sources revealed for now.
So, your sources are practically implying that  Canon will make yet another DIGIC circuit in a few months! Fascinating! And we have to believe this because?

you know that the digic 6 is in canon cameras since april 2013 (SX280 HS)?

and you think 2 years are to short a timeframe for a new generation? fascinating!
If the next camera comes Spring 2015 I think it will have Digic 6 even if it is supposedly on a compact camera too. If it comes next year (Fall 2015) maybe.

Lenses / Re: Tamron 15-30mm f/2.8 Full Frame Lens to be Announced Tomorrow
« on: September 12, 2014, 08:15:29 AM »
From the images, it looks like a built-in hood with slightly bulbous front element. That's a bad news for filter users :(
+1 Exactly! Add 1mm and you get a 2.8 zoom lens that takes filters!
I can only assume, that filter users will opt for 16-35/4 anyway, as you usually use filters on tripod at f/8+ and don't care much for the speed of the lens. Conversely, action shooters could not care less about filters and will go for this lens, if it proves to be better than C16-35v2 or T16-28...
Landscape Astrophotographers though will either continue using a 14mm which has a bulbuous front element too or will opt for a 2.8 zoom lens with no bulbuous element for better protection (from light) via a hood. At least this is what I need for that kind of photography...

That, and a coma free lens ...  :)

Third Party Manufacturers / Re: Nikon D750 to be Canon 5D3 competitor?
« on: September 07, 2014, 10:01:50 AM »
- similar number of AF points, suggesting similar AF capability

That makes sense because as we know, all AF points are the same – only the number of them matters.  Line vs. cross vs. dual-cross, f/5.6 vs. f/4 vs. f/2.8 baseline accuracy, spread across the frame, those don't matter at all.
This time there was no coffee at my desk so there was no risk of destroying my laptop  ;D  ;D  ;D

The rumors need to start materialising as lenses. The newer cameras (before we even get to 45 or 85MP as been rumored here) such as the 6d show up the problems of the EF-17-40mm f4L,  EF24-105mm f4L both of which have pronouced chromatic abberations at 17mm and 24mm respectively. As sensors improve the faults of lenses masked at 8, 10, 12 or 18MP now show up and this undermines the system ability to produce great results. Sigma have shown improvement are possible (so has Zeiss at a price) and still remain competitive to Canon pricing.

A 24-105 II L really would be nice, especially mated with a 100-400 II L combo. Very versatile!

+1 for the 24-105L II lens. This is the most versatile lens Canon makes.

Also, Canon- a 14-24 2.8 for under $2500 please.
Can I order my 16-35 2.8 III please ?  8)

@jrista:  John this is a fantastic photo. Could you share some process details that lead to this result?

The HDR result was pretty simple. I imported to Lightroom, then selected all five for this set, right-clicked and chose to "Merge to HDR Pro in Photoshop..." When that was done, I chose 32-bit, and "Tone in ACR". I then tweaked things a bit in ACR, mainly exposure, a little bit of curves, applied a gradient (like a digital GND) to the top to bring out the blues more, did some brushing around the sun (just to deal with some posterization), and that was pretty much it.
Thanks for sharing  :)

Coma test of Samyang 24mm 1.4

http://www.lenstip.com/330.7-Lens_review-Samyang_24_mm_f_1.4_ED_AS_UMC_Coma__astigmatism_and_bokeh.html

It is not coma free but it has much less coma than the Canon.

Reading though:

http://www.lenstip.com/330.11-Lens_review-Samyang_24_mm_f_1.4_ED_AS_UMC_Summary.html

I have some reservations(Quoting from the aboe lenstip link):

"Coma looks practically the same, no matter whether we use f/1.4 or f/2.0."
"Defocused diode images, positioned in the corner of full frame are practically the same by f/1.4 and f/2.0"

To sum up there is some doubt whether this is truly a 1.4 lens. Some findings are explained, some not.
