Canon General / Re: Official: Sigma 24-105mm f/4 DG OS

My guess is $999. The Nikon 24-120 is $1300, the Canon...well, we all know.

So, cheaper than the Nikon, more than what the Canon actually sells for, but it will have IQ to beat them both. That makes for a very strong seller.

I'm sure this will be huge for Nikon users. Probably a tougher sell for Canon users, as it lacks weather sealing. I suspect IQ will be the real deciding factor...more so than price.

The image is at least dimensionally consistent for a Nikon mount lens. The Nikon flange is 44mm across, so with a 82mm filter thread, 82/44 would give a ratio of 1.86. I measure the flange in this image at 139 pixels across. Multiply by 1.86 and you get 259 pixels for what the filter thread width should be. I've drawn that onto the image and it seems reasonable that this is where the filter threads would go.

If it's a fake, they at least made sure it was scaled correctly.

Lenses / Re: Testing Cheap Lens "Bowen 8mm. Fisheye"

I bought one for my brother's 60D, but couldn't resist trying it on the 5D Mk III. Really a great lens!

I cannot see how this price can be correct. Truly dumbfounding. I think Sigma is going to embarrass the S___ out of Zeiss when they update their 50mm f/1.4.

Software & Accessories / Anyone tried the Replichrome "film look"presets
« on: October 04, 2013, 03:15:41 PM »
So, I guess these are supposed to be a much better alternative to VSCO film packs. Anyone tried them? The reviews sound good. I wish there were a free trial...I realize that is not really possible with Lightroom Presets.

I've owned the both the Canon 1.2 L II and the Sigma. I sold the Canon and kept the Sigma.

Sigma pros:
vastly faster AF
actual manual AF
vastly better dust protection (with a filter on, the lens is effectively sealed)
around half the cost

Canon cons:
drive by wire manual AF
large gap between body and the barrel that moves in and out while focusing (dust entry point)
high price

Canon pros:
half stop faster

This comment on that page was intersting:

"i work for zeiss in germany and i have some colleagues from university who now work for canon germany.

i can´t tell you much because i don´t know much about it.. but my canon colleagues say something big is comming in october. kind of a suprise."

If you are a pixel peeper, you should check these out... shot RAW and exported from LR full-size at JPG 85 Quality. Please let me know what you think:

35mm f/1.4 @1.4, ISO 200, LR tweaks to color, contrast, exposure:

35mm f/1.4 @1.4 ISO 3200, LR exposure pushed 2 stops, Highlights -100, no NR or other tweaks (shot in difficult fluorescent lighting):

18-55 kit lens @3.2, 26.5mm, ISO 800, LR tweaks to exposure and color, no NR:

60mm f/2.4 Macro @2.4, ISO 200, no tweaks whatsoever (be sure to check out his moustache @100%):

EDIT: More
Kit lens @2.8, 18mm, ISO 200, no tweaks:

Same image as above but with LR Sharpening (Amount: 40, Detail: 75) and +28 Vibrance

I bought the X-E1 a month ago with the 18f/2, 35 f/1.4, 60 f/2.4 Macro, and 18-55 f/2.8-4 OIS.
I absolutely love it. I did something I've never done before...I took a vacation and left my 5DM3 at home.
This is my day-to-day camera for sure now. Obviously, the AF speed can't compare, but it's certainly fine for travel/street photography.

I am going to sell the 18mm f/2. It's only one stop wider than the zoom and is less sharp.

I don't get the appeal of the X-Pro1 over the X-E1. I would never use the optical viewfinder. The higher rez EVF of the X-E1 more than makes up for it. I want to see out the lens, either through a DSLR's mirror or through an EVF.

Regarding the JPEG banding/posterization... If you are saving to JPEG from Photoshop, always use Save for Web. you get a nice little preview of what the end result will look like once colorspace, resizing, compression, etc. are applied.

I feel like 90% of the grief that people hear about are from older/cheaper models from Sigma.

I was talking about the 35, the 18-35the 50, the 85. I have never tried the first two (hence the use of the words "seems" but I have seen quite a few complaints about the AF). I have my own experience with the 50 and the 85, and the AF was below any acceptable standard, the most problematic was the AF was heavily dependent on the distance. The same complaint that I hear about the first two, it must be a Sigma thing.

I had to return the Sigma fisheye, the latest "silent upgrade" model for various problems.

So, you've had grief with two pre-Global Vision lenses and have seen complaints about other lenses you haven't tried...(complaints that haven't shown up in any of the reviews I've read.) Based on this you feel qualified to contradict the premise of this thread?

I am not sure that they improved the quality. They have a few new lens designs but the AF problems and the copy variations seem to persist. Their build quality has been gradually improving long before the event you mentioned.

I've owned the total of seven Sigma lenses and used them with 7D, 5D Mk II, and 5D Mk III and the only one that had any problem with AF was a 50 1.4 on the 5D Mk II. It was inconsistent in low light. I sold that lens (which I had bought used) and later bought a brand new copy when I heard it performed better on the Mk III. It's true.
I feel like 90% of the grief that people hear about are from older/cheaper models from Sigma. The 35mm and the 85mm are stunningly sharp. The 17-50 f/2.8 OS was my favorite crop body lens. All the Global Vision lenses offer tuning and upgradeability through the USB dock. You really cannot go wrong with the new lenses.

Here is the link to the article.  It's a tour of the Sigma factory with some history on the company. The person receiving the tour comments on the cleanliness, attention to detail, and optical testing of each completed lens... factors which could account for an improvement in quality.

This is all part of the company's new Global Vision that they launched in 2012. You can read about it at the link below:

It is a great lens. However, I sold mine in favor of the Sigma which renders closer to the 50 1.2
