Photozone Review: Sigma 150-600 Sports on the 5DS R

Sigma's better 150-600 lens on the 5DS R:
http://www.photozone.de/canon_eos_ff/977-sigma150600f563sports?start=1

Recall that last week they ran the same test on the Tamron 150-600:
http://www.photozone.de/canon_eos_ff/976-tamron150600f563vc?start=1

An interesting disclaimer is made before resolution is reported:

"Some may be surprised by the relatively moderate performance figures below. Please note that two effects are coming together here. First of all - the "common" peak performance on the EOS 5Ds R, out test camera, is reached around f/4. The Tamron lens is slower than that thus diffraction effects are already decreasing the resolution potential at all aperture settings. On top of that comes the fact that we are talking about a super tele lens here. Remember that this is a chart-based MTF system and the longer the focal length, the longer the distance between camera and chart. Beyond 300mm air diffusion is starting to have an impact and as you can conclude, it's correspondingly more pronounced the more you zoom out. Please keep that in mind here."

(I either missed this completely last week with the Tamron review or it was added after the fact. I'm aware MTF testing needs to be modified with longer lenses, but for those who know this better than I, is this an appropriate statement?)

At any rate, comparing the two lenses just from a resolution perspective:

150mm @ f/5 --> Sigma clearly better
150mm @ f/8 --> Tamron largely closes the gap as you'd expect

600mm --> Sigma better, stopping the Tamron down doesn't close the gap.

1DXII Plate

Several years ago when I bought my first sturdy tripod (a Gitzo) I bought a standard Gitzo plate to go with it. It had a thin layer of cork glued to it and when the plate wasn't horizontal to the ground (i.e. a vertical or tilted) the cork would slowly move entirely defeating the purpose of a tripod. A photographer at the park I was visiting told me about RRS and I've stuck with some kind of form fitting plate ever since. At this point I probably wouldn't risk losing some photos to saving $ on a plate. With my luck it would work great until I got up early to hike to to a beautiful location the sunrise would be perfect and then my plate would start moving... Murphys law. :D

Sigma 50-100mm f/1.8 DC HSM ART Reportage

The non removal tripod collar is really a non issue once you move it out of the way-it does not get in the way.

I have used it several times now, both on my full frame and on my crop. The lens is ridiculously sharp wide open and is a great addition to my collection.

Here is a full size portrait at 100mm at 1.8. I used LR Screen Standard sharpening upon export with a slight crop.

The second one is from a cosplay session and was shot at 2.8 at 67mm. I was shooting HSS with my 5D MKIII and the 7D MK II would not go into HSS. I stopped down to 2.8 but still blew the exposure out and had to recover it in post. I gave up with the 7D MK II because I could not get the same exposures as the MKIII during the shoot. Once I got home, the camera entered HSS no problem..who knows what I was screwing up.

New 50mm On Coming Soon? [CR2]

Did I ever mendion that i think people who make "everyone" statements are poorly informed/educated (to say it very very friendly)?

You just quoted two posts that did not have the word 'everyone' in it at all. Could you be more specific?

If you are referring to the 'everyone' in my frequently posted "canon please give us this lens" graphic, the use of that word is clearly being used for comedy purposes to express a plurality of folks who want such a lens. It's not being used to express an ignorant worldview or belittle others' opinions.

Keep your sense of humour ahsanford, you're going to need it over the next few years when you don't get your EF 50mm f/1.4 IS ;)

Preorder: Canon Speedlite 600EX II-RT & Accessories

midluk said:

So what exactly is the difference between the 600ex-rt II and the or original 600ex-rt?
  • faster recycle time
  • higher number of subsequent, rapid flashes before the mark II model overheats and turns off.
But the "faster recycle time" only applies when the CP-E4N is used. Normal recycle time using AA batteries without external battery pack seems to be unchanged.

Further changes:
  • removal of remote trigger output for remote triggering pre 2012 cameras
  • changed accessories mount (not compatible with old gel holder)
  • some minor UI refinements (e.g. progress bar for recycle status)
  • RT master fires any slave units that is ready, not only when all linked units are ready again
  • larger flash case with space for all accessories
See also http://www.learn.usa.canon.com/resources/articles/2016/speedlite-600ex-ii-rt/speedlite-600ex-ii-rt-whatsnew.shtml

Thanks for the link that really explains it in more detail. I still just velcro my gels to my flash on 600ex-rt's the old accessory was a joke unless it was pointed right at the subject which I rarely do. I'm usually trying to bounce off of walls. The only thing though that would be the draw to upgrade is that it doesn't overheat as fast but that's it. That's not nearly enough to upgrade the the mark II. Why waste the upgrade without improved ettl the most basic function that is in need of an upgrade by canon. This is a disapointing upgrade to the 600ex-rt and now I have to also buy another battery pack for marginal improvement?! I don't see why they couldn't have at least just left the battery pack the same.

Lube

I found the graphite which is in the lenspen to clean lenses works pretty well when you dust a little on the filter thread with a brush.

When I have stuck filters on top of eachother I have resorted to putting them in the freezer and then holding the outer in in my hands to heat it up so that it expands more than the inner one. I wouldn't suggest freezing lenses on purpose though.

For polarizers, i usually go over them with my fingers before screwing them on. Anything to prevent them from being really dry.

Anyone had experiance with the EF100-400 f4.5-5.6L IS USM II & EF1.4EX III

I currently use the kenko DGX 1.4 converter a great deal with the new 100-400 which works extremely well on my 1D IV and the Sony A7RII but there have been some compatibility issues with the 5D3. Quality wise it is pretty close to the mark III canon. Here are a couple of examples, and these are also cropped since I rarely consider 560 (x1.3) long enough :) This teleconverter will also work with autofocus on older canons that don't officially focus at F8.

Review: Canon ImagePROGRAF Pro-1000

Hector1970 said:
Are Canon doing the opposite numbers wise with printers. Is a bigger number a better printer.
I thought it was Pro-100 --> Pro-10 ---> Pro-1 in order of importance (Pro-1 being top of the range).

That's not a Pixma Pro printer. It's the entry level of the ImagePROGRAPH line. You'll fined bigger (and more expensive model) in the line, i.e. the 4000. It's the Pixma Pro numbering scheme a bit unusual, probably it was made to mirror how Canon numbers cameras.

Hector1970 said:
a) Overly complicated

Where is written fun should be simple also? :D Is processing images in LR or PS easy? No...

Hector1970 said:
c) There are too many options up front, too many sliders, too many adjustments possible.

The "Pro" word should have made you aware of that. "Pros" like control to achieve the desired result. "You press the button, we do the rest" was Eastman motto, but aimed a truly amateurs...

Hector1970 said:
d) Its so hard straight out of the box to do a simple thing like a borderless print. You'd almost need a PhD in printing to work out how to get rid of borders

Setting "borderless printer" in the driver is so difficult? ;)

Hector1970 said:
e) The error messages particularly in Lightroom are bordering on useless to explain what's wrong

Sometimes application like LR can't do anything but reporting the error from the printer. Which may be or too uninformative, or too technical - and hope they are at least written using the correct syntax...

Hector1970 said:
g) Those preprinting routines the printer goes through are a right pain. Replace a cartridge and it does it all over again.

Guess Canon would avoid them if it could. Handling liquid stuff is usually more complex than handling solid one.

Hector1970 said:
h) While print profiles really improve the quality of the images its a nuisance too.

One reason is commercial (Canon may like to sell its own paper), the other is nor Canon nor Adobe control what 3rd party papers make available and their specifications. It looks to me it's the paper manufacturer in the best position to create generic profiles for its products. Anyway, most pros will make their own, or have them made.

Maybe some users may start to share the profiles they made (if they have rights to do so, of course), to help others.

Hector1970 said:
i) Custom paper profiles while excellent also require extra work

Or extra money if you outsource them ;) True, but the actual technology has no way to get rid of them. There are too many variables to control if you need the "optimal" results, and it's good you can create them as you need.

I made once the big mistake of buying an HP PhotoSmart D7260 which didn't support custom profiles and offered only two "ICC profiles": AdobeRGB and RGB (a bit strange for a printer...) Then attempted to process the images itself. Usually returning a dreadful result - it was designed around a very simple "direct-to-printer" workflow.

Since I switched to a Pro-10 I became much happier.

Hector1970 said:
j) Its an expensive business. I don't mind paying for Ink or Paper. Having to keep replacing Ink is very irratating. The printers are so big surely there is room for much bigger ink sizes.

The ImagePROGRAPH has bigger cartridges (the Pro-1 has also bigger ones than the -10 and -100) - just look at how much they cost. Not feasible for printers aimed at a different market. Many Pixma Pro users may prefer to pay $12 than $80 to replace a single cartridge - even if for the same ink used they pay a little more - but they do diluted in a longer time. Sure, if you print a lot you need a printer designed for a lower cost per print.

Many business and - many hobbies as well - are expensive. The paints and pastels my sister uses for her artwork are expensive as well.

Canon EOS 5D Mark IV Talk [CR1]

CanonFanBoy said:
I've got to say that I really do not understand the demand for GPS. Nothing against it. I just don't understand it.

With GPS one does give up some privacy, just like with a cell phone or your car's navigation system.
<snip>
Any file that I put on the web has had the metadata removed from it, so I have no worries about people data-mining my pictures.....

Besides, On the Day I got my 7D2 I turned the GPS off....... I suppose that some day I should turn it on to test that it works..... maybe in 2018.... or 2019....

For me, GPS is a feature that has no appeal.... but I am not self centered enough to demand that nobody gets it. After all, Canon would not have put the feature in if there was not a significant demand for it and probably figures it will increase sales.

GPS and wifi can both be turned off. Touch screen too. So these should be non-issues.
I leave my phone Location service (GPS) off 98% of the time, but every once in a while it is extremely useful.
One of my friends uses his 6D GPS when hiking, because it tracks his route, which he likes to use later.

I would probably leave GPS and Wifi off most of the time on my 5DIV when/if I get it, but I'll be glad to have the option.

They aren't "issues" with me either (GPS / wifi). Just don't care about them nor do I care for them.

If it is on the camera it is on the camera. If it ain't, I am fine with that too.

Love touch screens. :)

1DX owners are you upgrading to the 1DX Mark II?

applecider said:
Schultzie what did you get for 1dx?

Buy body or kit w or wo hard drive curious?

From my prior list:
applecider said:
Still on the fence, will a switch allow me to get photos that I can't now?:

Pros for me:

-More F8 points in wider spread, better autofocus with all lenses
-Possible better high iso noise (as yet undocumented to me)?more pliable files
-Possible better DR in lower iso again show me the proof
-Reasonable cost-the dollar yen will probably be worse in a year or two
-CFast card speed
-GPS
-available while I can still use heavy equipment
-higher Mp count better for cropping "reach"

Cons for me:

-inconvenience of switching (selling 1dx, etc.)

Not important to me I'll take them, just not important to a buy decision:

-higher frame rate
-antiflicker
-4K


This list is still developing so reading the new owners comments in a vacuum (to prevent GAS contact).

I add the 5d IV factors to push me toward 5d4 rather than Dx mii

->30 MP
- same f8 focus as Dx mii
- same high iso as mii, lower iso DR improvements
- 7 or more fps

I note again that Roger at lens rentals says that high MP makes all lenses better, and at least in some recent posts art Morris is singing the praise for the 5 D SR .

I ditched my 5dsr in favor of the 1dxii. While the images were great and sharp, everything else about it was a big disappointment. Even the AF system which shares the same functions as the 7d2 and 1dxii was very slow with moving objects. Even the 7dmarkii was noticeably better at tracking. The camera you use should be based on the system and not just sensor performance. Im sure the 5d4 will be a winner at what it does. Just keep in mind more MP doesnt automatically make it better. It can in fact slow down everything else in the camera and in post processing. Keep your passion at heart and decide what you really need for the kinds of photos you shoot.
