The dynamic range on both is lacking...


Oh wait, wrong thread again. Both should be fine in rain.

Just think about how much better these photos would be with more dynamic range! Oh wait...wrong thread again. Damn.


Beautiful shots everyone!

I went out shooting today with my 5D3. Got some great shots.

Then I thought...you know what would make these photos even better? Zero freaking shadows!!!! I pushed and pushed in post processing until there was nothing left to push. Man...the noise in the blacks was awful. I could barely make out a sign that was in some deep shade in the far upper left corner of my photo. After some noise reduction, and zooming in to 400%...I saw what the sign said:

Beware of Internet Trolls.


I was blown away. Had I been using the D800e, with its 30% better sharpness compared to the regular 800...and it's amazing dynamic range, I wouldn't have had to spend so much time figuring out what the sign said.


Tomorrow I'm going to go back to a creepy looking bridge I found and see what Trolls I can find in the shadows when I post-process.



Pro Tip: Since trolls have never seen people in real life, they easily get scared when an actual human is near by.  ;)

I'll shoot from a distance and just crop in.

Oh no! Damn...I wouldn't be able to crop as far because of my low 22 megapixel count!!!! If only I had the 36 MP monster that is the D800.

Damn Canon, again! Ugh.

Third Party Manufacturers / Re: DOUBLE SMACKDOWN on Neuro

Would you believe the results of testing a drug for Alzheimer's disease in a population of 20 year olds with asthma? 

DOUBLE-SMACKDOWN!


 :P :P :P :P :P :P :P :P :P :P :P :P :P


Do you perhaps wear a spandex jumpsuit and grease up with vaseline before you come post here? I take you for a WWE/F fan.

 :P :P :P :P :P :P :P :P :P :P :P :P :P

But seriously, you've shown me the light/detail in the dark underexposed world I've been living in (get it? 'Cuz we're talking about DR). I'm selling my gear for Nikon and Sony stuff. I'm just worried about resale value now since my Canon gear is so subpar. Ugh...if only you were here on Canon Rumors sooner... before I bought everything.

Really my purchasing all this non-Nikon stuff is your fault. If I can blame a casino for gambling too much (which I did BTW), then I can blame you for my mistake in camera equipment.

81
Very ignorant of you. Please go see d4s. ;) It outperforms the 1dx period in sensor tech.

The performance of the two is nearly identical above ISO 800, and the D4s has a DR advantage below ISO 800.  Plus, I can't hand-hold Nikon's 600/4.

Also…

Sony sensors do perform better at all ISO ranges.

AFAIK, Sony doesn't make the sensor in the D4s.  Ignorance must be bliss for you… 


Gee, Neuro.  Would you write up the drug test studies with cherry-picked data too?
In the crop sensor and smaller world, the results are notably different.

Would you believe the results of testing a drug for Alzheimer's disease in a population of 20 year olds with asthma?  Note that I said my Canon sensor in the use case I described.  The point was, people make assumptions about their own, personal definition of 'better' without regard for the fact that their needs don't define the needs of everyone else.

Come back when m4/3 is outperforming FF sensors, we'll talk.

I wouldn't bother anymore. Clearly the Nikon/Sony match-made-in-heaven is superior. You and your 1DX will have to just continue taking sub-par photos with poor dynamic range. Even if you think you've got a great picture that you've just taken, Dilbert and the crew here will assure you that your photo is lacking in sufficient DR for it to be worthwhile.

See the light. Spend more time on the internet researching this, and take less photos with what you have. C'mon

Technical Support / Re: Multi-controller joystick 5D MKIII jumped off
« on: June 01, 2014, 01:08:46 PM »
It's quite common. You can probably just push the joystick back into place and it will work.

The only problem is the rubber bladder/seal is now broken. If you send it to Canon they will replace it; the catch is that the joystick's rubber is attached to the whole rubber bladder surrounding the body, which they will have to replace.


If you don't need the complete weather seal I'd just push the little thing back on and be done with it. I doubt even in rain if it will affect it. After all, the 5D2 never had a rubberized joystick.

Nikon has completely given in to the whims of customers in protecting shadows (because we all know the importance of exposing shadows to the point that they are no longer shadows) but that sacrifices highlights at the other end of the spectrum.
Canon focuses on just the opposite, but according to the masses they do not capture as much shadow detail in giving you that greater range in highlights.

Technically, in the scope of capturing light, once the upper end of the spectrum is blown - it is gone - and therefore should be the end protected the most. However the average photographer (aptitude or numerical demographic) has been made to believe that broad dynamic range in the areas of a photo that you were not intended to see (shadows) is the most important part of photography.

85
So what is the consensus on this lens: do you all think it's a safe bet, or should I maybe check back later after these initial production runs?

86
All of this has me quite worried and I am thinking about cancelling my order. I don't mind spending a bit of time with FoCal calibrating a lens, but I don't want to be bothered with having to spend even more money buying Sigma's dock just to calibrate it at every conceivable focal distance. If Sigma can't design a lens that has decent focusing without the ridiculous tinkering they should bloody well just include the dock with their lenses.

I haven't even received my copy yet and I am scared stiff.

Got my new, second copy, 50 Art today. I seemed really great at 0, at least farther away than 3-5 meters. I ran it through FoCal, first once where it said predicted afma +50! I decided to realign my setup as something had to be wrong. Did it again and it switched between +21 and +15. And it kept giving me the old "focal has tried focusing 5 times, but quality of focus varies a lot.. etc" but i continued the test and ended up with +11, I had dialed in +5 in camera. All this done at 50x focal length.

I went outside and +11 at infinity was seriously off, put it back to 0, and it works pretty well. I went through the values for the three other distances between 0 and +11.

I ended up with 0 in camera and the lens via docking set to, +8 at mfd, +6 at 0,7m, +5 at 1,5m and 0 at infinity. For now it seems really nice and consistent and not like the other one I had. BIG pinch of salt if this stays this way, I am not saying it's perfect now, but today it's perfect, we'll see over the next week how it evolves. I hope nothing happens...

One of the posters (I forgot to record the name, damn it) at dpreview.com said this on Nikon sensors. I saved the quote to ask Neuro about, but since it seems relevant to this thread I'll just post it.

Just ordered mine. Fingers crossed that it's a good copy unlike the debacle I had with my Canon 24-70 II.

I'm watching with interest how everyone's repairs come through.

Lenses / Re: Stacked TCs - 1.4x III + 12mm Extension Tube + 2x III
« on: May 09, 2014, 12:45:02 AM »
Sorry if this is a bit off topic, but since we're talking about extenders and extension tubes already I don't see the need to start another thread.


If I use a 2x extender and then a 12mm extension tube...is it possible to use the 100 f/2.8L with this combination?

Yeah, I think I've done that. The 12mm extension tube should make the 2x extender fit any lens (although I'd be careful with ones like the 85L which has a very exposed rear element). With a macro lens like the 100L you'll get a pretty good setup for smaller insect subjects, although I'd stop down and you'll lose infinity focus as always with the extension tubes.

Thanks! I just tried it... Man, unless the camera is on a tripod it's next to impossible to hold it steady. Sharpness really suffers, even when stopped down to f/8.

The lens retained it's f/2.8 aperture, however, which was cool!


Thanks again for the information.

Well remember, the reported aperture won't take account of the extender, since the camera body won't know it's there. So "f/2.8" is actually f/5.6. Also, at that magnification (up to 2x), use of a flash is almost essential. Add a flash, set it to the sync speed (e.g. 1/200), and you can hand hold easily. I was hand holding to 10x magnification today, albeit half resting on a surface (MP-E at max + 2x).


Interesting about the aperture. I was using a flash -- 580 EX II -- at exactly 1/200. Still, at extreme close-ups of subjects...I did not have much luck keeping it steady.

I also found manual focusing was an absolute must. Normally with Macro I like to manual focus anyways, but I sometimes use autofocus to get an approximate...but this lens combo did not want to focus at all. It just kept hunting and hunting.

Anyways, it's cool that this can be done. Gotta love tinkering with all the equipment. Thanks for the help.
