Lenses / Re: Something with 50mm L lens that make it different
« on: July 21, 2014, 09:11:48 PM »
I know the 50l has some spherical aberration built in to its design that gives a certain look that most lenses won't  under specific conditions. Nikon makes a 135 DC that has a control ring for that.

Now you got me going. All this controversy makes me want one now.

P.s canon price watch has it listed for $1319.00 "cpw street price"  "authorized canon dealer" they broker deals and sell through thier site? I would like to get one and that's the best price I see. Any experience buying there?

As I have consistently said, there are good reasons for choosing one lens over another, even the 1.2L, but lets stop the bull about unique look when nobody can actually back it up

The lens does look unique. You have to admit, the extra jumbo fatness and the red ring on the front look pretty cool?

Lenses / Re: Tamron lenses --> annoying zoom ring
« on: July 18, 2014, 06:40:23 AM »
i prefer it with the zoom ring on the front. especially with heavy lenses. better support and you can use your pinky and thumb for focus fine tuning i guess i just got used to it that way.

it does seem faster, especially with the 2xiii, it was already really good with the 1.4xiii as the blogger pointed out. i have noticed an issue that was also pointed out by ephotozine (i think it was them). at 120mm and around 1/200s, there is a glitch in the os. i haven't checked to see if that's been fixed?

Lenses / Re: Need a 600mm. Don't want to pay for one
« on: June 05, 2014, 10:02:18 PM »
Thanks everyone for the comments. I think ill errr on the side of the tamron. I really want 600mm so think it would be better (and cheaper) to go with that. And just suffer any slow af at the long end or any softness wide open.

i have the sigma and the tamron. the sigma is better with canon and kenko extenders than it is with the sigma extenders. the sigma bare lens and with a 1.4tc is better than the tamron. the sigma with a 2x is about the same as the tamron but the sigma is huge and heavy! i use the tamron all the time unless i really need 120-300 2.8 or 420 f/4

I have them both and I think they are both great but the 70d is a better all around camera: dpaf, touch/swivel screen, pop up flash. I use the 6d for low light, wider and shallower depth of field when I want it. Get them both if you can otherwise go for the 70d.

My .02

p.s. I don't shoot video much but the 70d is good for it

Photography Technique / Re: What Lenses Do You Use for Panoramics?
« on: May 08, 2014, 07:01:04 PM »
i have done a lot of panos and qtvr using a crop body and a 15mm fisheye with a panosaurus head then ptgui for the stitching

with the fisheye 2 rows portrait orientation 45 degree increments one row 30 deg and one at 60 deg plus a zenith and nadir. thats 18 shots total

At the risk of being considered rude, my comment is one of suspicion.  The author said that he put the two lenses on two different 5D3s and took casual snapshots around his home.  So how is it that in each pair of shots, the composition and focus are so identical?  And how the heck did he get the dog to stay absolutely perfectly still while he switched cameras?

LOL

My dog is camera shy and kind of freezes up and looks away. I just had one camera in each hand and would pay attention to the composition in the corners of each shot and duplicate, as well as kind of brace my shots in the same position. I really just tried to get a variety of shots to see how the lenses might differ.

Thanks for doing the comparison. I am looking at getting one of these 2 lenses. I have some sigma lenses and am generally happy with them. I know the new sigma is supposed to be really sharp but the canon shots look really good too.I just really like the way the canon looks on a camera. Its got a unique extra fat stubby look that makes me want to buy it just for that reason.

Thanks for taking the time to do the comparison shots, it looks like the ones from the sigma are a bit brighter at the same settings?

Lenses / Re: Review: Sigma 50mm f/1.4 DG HSM Art Lens

The dock makes changes to the lens regardless of  what it is mounted to. I have found that once I set it up using one body that its been good on others. I do have a case where my 120-300 is proper on 2 70d's and a 40d but was backfocused a bit at 300 on the 6d. Instead of reprogramming the lens I just set the afma on the camera to-5 on the tele end and its fine.

So to me the calibration you do with the dock is something that I think should have been done at the factory. Anyhoo, the dock is very useful but it does irritate me that its necessary in the first place

Did you find that the -5 on the 6D was good for all distances?

Yes, it seems to me the way it works best is that you use the dock to calibrate the focus and then its within the tolerances you would expect on a particular body. If you put the lens on another body you may get a slight front or back focus due to a bit different allignment between the camera and lens but its consistent and easily correctable with in camera afma. You could use the dock to recalibrate the lens on different bodies but then you would have to do that every time you change bodies. The lens does not recognize what body it is mounted on and set itself accordingly like the camera can do with different lenses.

I have the Sigma 35 Art and the dock. They do allow you to program in different AFMA values at 4 different distances. Like 6", 18", 4', Infinity. I was able to really "dial" in my lens using their dock. Plus I get future firmware upgrades.

I suggest getting the dock just for future proofing the product.

How does dialing the different values for different distances work for multiple bodies?  Is 1 set of Sigma dock distance values good for all bodies, or does it have to be done and recorded for each body?

The dock makes changes to the lens regardless of  what it is mounted to. I have found that once I set it up using one body that its been good on others. I do have a case where my 120-300 is proper on 2 70d's and a 40d but was backfocused a bit at 300 on the 6d.

i would suggest that anyone who has bought this lens and is happy with the iq but is having some difficulties with the af should get the dock. it seems the new global vision lenses can have af issues that cannot be set correct with in camera afma. the af problems are usually distance dependent which is adjustable with the dock. many of the inconsistencies will be corrected because the lens will not be predisposed to front or back focus at a given distance so slight variations in focusing are more likely to be in the acceptable range. its a bit of a hassle doing the calibration but worth it if you want to keep the lens.

the 70d is good for macro with the flip screen an dual pixel focus. the ef-s 60 goes really well on it as a macro and portrait lens, its nice and small, reasonable price. if you are looking to do video  the 70d is best. its a really good all around camera. it feels modern in use. we are lucky nowadays in that there are a lot of good choices out there and you don't need to spend a ton of money to get good results.

One of the earlier reviews (ir/slrgear) points out that the sigma traded a bit of sharpness for higher micro contrast and that even though the otus had slightly higher resolution on the charts that the sigma looked sharper to the eye. They said that they would go with the sigma even if both lenses cost the same.

 http://slrgear.com/reviews/showproduct.php/product/1677/cat/30

I learned from a discussion on another thread that the canon 50 f/1.2 has really nice bokeh due to that being a primary factor in its design. Apparently some spherical aberration was designed in for that. The canon probably has more consistant af? I would like to see some real world samples comparing the canon and sigma because for me the choice would be between those two lenses and not the otus, even if they all cost the same.
