EOS Bodies - For Stills / Medical joint overload by heavy dlsr?
« on: June 27, 2013, 04:59:41 AM »
Currently I seem to be getting into a chronical a medical condition because my equipment seems to be too heavy for the way I handle it: The whole 60d+70-300L+600rt-flashbracket package rests on the last joint of my ring finger, and my physician advises me strongly to change the way I shoot or stop doing it, at least for 8-10h straight every other day.

Problem is: I don't know how to even the load on my hand, esp. with the flash bracket because I cannot attach a hand strap at the same time. There are lots of people with expensvie (i.e. heavy) equipment on CR, and I'd like to ask you for your advice:

* Where does the whole camera load sit with you (with me it's the ring finger and a bit of the index finger of the right hand)? Do you carry the weight rather with the left hand that holds the lens?

* Does a battery grip help to even the load because you can grab the camera with the whole hand?

* Does a larger grip like 5d2/3 vs 60d/6d help because you need to cramp the hand less?

Edit: Using a monopod is not possible for what I'm doing...

One more reason to use Magic Lantern not only for video: With the new capability to read raw sensor data they've got two great new amazing features for still shooters.

* Raw histogram even in "normal" photo-mode (& of course live view): Unlike the Canon version you can see beyond the jpeg range, this should be a great even for people who never used ml before. Also it's amazing that Canon *didn't* add this feature in their fw, not even for 1d cameras...

* Automatic ETTR: Now you can auto-expose to the right to max. dynamic resolution & minimize noise with clipping prevention!

* Silent DNG burst pics (capture the live view image w/o flipping the mirror) - it's not full raw resolution and it might show the usual movie moire, but you can capture successive shots in 14bit raw as long as your cf/sd card can keep up :-) ... for example my 60d takes 53x 1737x1156 shots in <10sec, other more newer & better camera bodies have a larger lv resolution and deeper buffers für 100+ shots.

These features aren't yet available for all cameras, if you want to try you've currently got to use a nightly build: http://www.magiclantern.fm/forum/index.php?board=33.0

EOS Bodies - For Stills / Do you trust your camera?
« on: May 06, 2013, 06:07:02 PM »
When shooting scenes that I consider to be "keepers", with my 60d I am always taking multiple shots because I fear the af won't be spot on. The actual "real" af misses are maybe 5%, however more often the large af points miss slightly when trying to af on small points for example the eyes of a horse looking towards me.

Another issue is IS which only improves statistically so even with good IS systems like 100L and 70-300L I always take multiple shots because in my experience there are visible differences even with the same settings.

That's part of the reason why I'm now @120k shutter cycles, apart from running focus stacks and bracketing. Also sorting through very similar shots and deciding which is a little better than the other is annoying and time-consuming.

I'm wondering: Am I doing something wrong or different than other people? If you have a 60d or other cameras (what about 6d/5d3), do you trust your af and lenses so much that you  take just one shot even of important scenes?

Lighting / OC-E3 ettl-cord original vs 3rd party quality?
« on: April 25, 2013, 06:08:09 AM »
I recently ordered a Yongnu OC-E3 ettl cord from the other side of the world because it's so much cheaper than Canon. After some time having it on a flash bracket the metal base plate on top of the adapter where the real flash goes started to wobble, and recently it came completely off - the metal screws with the hotshoe were torn out of the plastic plate.

This doesn't come as a complete surprise since having a heavy 600rt flash mounted in an angle and walking around with this puts quite a torque on the base plate of the ettl cord...

... My question is: Is the Canon original any better, or are there sturdier 3rd party oc-e3 ettl cords? The Yongnu otherwise is fine, but the metal screws into plastic is just cheap and cannot take any strain at all (at least my copy).

Edit: Added pictures with torn off base plate

Third Party Manufacturers / "I am boycotting Nikon" campaign
« on: April 05, 2013, 01:32:36 PM »
For once, I'm really happy to be a Canon shooter - no matter what the dynamic range is :-)

Animal rights activists have targeted (doh) Nikon for a campaign because the evil empire is not only selling cameras for shooting (doh) baby pets but also rifle scopes so you're able to take not only the picture back home, but also the real thing... plus they sponsor trophy hunting in Africa for watermarked shots.

If this is over the top or a legit criticism of business practice is up to you to decide and I certainly don't want a political discussion or even a flame war, but I'm posting this as information because no Canonista should be ignorant about public relation events that for once hurt the main competitor:

Lighting / Does the flash pulse when <x-sync & hss on?
« on: March 31, 2013, 05:12:52 PM »
I always thought this was self-explanatory, but on the other hand there might be a reason for the Canon hss button and that the flash doesn't auto-enable hss when >x-sync:

If I shoot below the x-sync limit (1/250s on my 60d) and have hss on, does the flash do the usual short high-power x-sync flash or does it do a continuous hss pulse like when shooting with >x-sync?

Feel free to write "rtfm" as long as you give the answer at the same time :->

Software & Accessories / SD card min. write speed?
« on: March 07, 2013, 02:30:52 PM »
I'm currently using a 2010 32gb SankDisk Extreme with "30mb/s" on the sticker. Since the prices have dropped a lot since I'm wondering if getting a newer card would improve my raw+jpeg continuous burst rate significantly - currently I'm using a 60d but will get a 6d sooner or later.

* Does the *minimum* write speed depend on the size of the card, i.e. is a 32gb card better than a 16gb one except for the obvious storage difference?

* Does my older 60d still profit from the improved write speed of the current Sandisk "Extreme Pro" with 95mb/s on the sticker, or is the a newer uhs-1 sd controller like on the 6d required?

Thanks!

Lenses / 2x cpl as nd fader?
« on: February 27, 2013, 12:57:01 PM »
I recently bought a 10 stop nd filter and a cpl filter. Since the 10 stop is very nice for the usual people removal, water/sky blur as predicted by some it has to be accompanied by a brighter nd filter to complete the setup.

Question: I read that the nd faders are nothing more than two polarizers together, so if I add another b+w xs-pro mrc2 cpl to my existing b+w slim mrc that should do the trick?

This is my current research concerning the "stacked" solution, it even seems to have advantages...

(-) vignetting on ultrawide if stacking the same size
(-) more hassle to adjust, no scale
(-) iq loss due to more space between filters(?)
(-) uv leakage in addition to ir (like in non hot-mirror nd filters)

(+) another cpl is cheaper than a vari-nd
(+) cleanable since the two glass layers can be removed
(+) both filters usable independently
(+) it's possible to adjust the rear polarizer angle, important for the usual cpl shots with added nd effect

Lighting / POLL: When will Canon release the 430ex2 successor with rt?
« on: February 27, 2013, 07:17:25 AM »
It has been nearly a year after the 600ex-rt release, and not even a rumor has surfaced about the 430ex2 succesor - just the theory that Canon is bound to update the "little brother" sooner or later. Will they indeed? Vote here and let's see

EOS Bodies - For Stills / 6d w/ eos remote and tablet connection?
« on: February 26, 2013, 03:37:39 PM »
Since I'll buy a 6d sooner or later, I'll need/want a compatible Android device for eos remote. Trouble is: Canon states that *tablets* are not guaranteed to work - has anyone got something like the Nexus 7 and tried it or are there any other links with experiences on this?

Lenses / UV or clear protection filter?
« on: February 16, 2013, 08:41:42 AM »
In my recent unintentional trivia series "I'm clueless, please help me out" I've stumbled across another question: I thought using uv filters were just a rip-off for old school amateurs who didn't know that a digital sensor isn't sensitive to uv - or for people who find a uv filter that is cheaper than a comparable clear filter.

My web research supports this, but I was told that just because it's in the Internet it isn't necessarily correct... and I've recently come across one application that might still prove a need for an uv filter except for protection or lens sealing:

* Vari-nd filters or two stacked polarizers - in contrast to "real" dark glass nd filters, they let uv pass and though the sensor is not very sensitive to uv, it still might make a difference with long exposures.

Is this correct? Are there any other reasons to get an uv filter over clear glass?

Lighting / Weird ettl ec behavior - is this just me?
« on: February 14, 2013, 03:53:17 PM »
With daylight fill/bounce flash I'm mostly shooting Av mode with fixed iso 800-1250, min. shutter speed set (1/60s - 1/250s on my 60d) and a little negative flash ec to prevent overflashing the subject or positive flash ec because the diffuser eats too much light. I'm also often using camera ec to control the subject-background relation, so most of the time it's set between +1/3 and +1 to allow for a natural background.

The weird behavior I am experiencing: When changing *camera* ec a little from 0 to +-1/3 the background exposure changes a *lot*, while the following 1/3 steps are relatively minor - so on my 60d+600rt camera ec is not a constant, gradual scale. Is this just me, my camera or my flash? Is the flash exposure depending on the camera body used, or do all the ettl2 Canon cameras meter the same?

Lenses / Is your midrange gear insured?
« on: February 14, 2013, 02:12:16 PM »
I didn't quite know where to put this question, so it ended up in "lenses" since these are the most expensive items in the bag.

The motive for me thinking about insuring my gear is that I though someone has nicked my 70-300L out of my bag today - but back at home I gladly saw that I didn't take it with me in the first place as I usually do. So: My current gear (camera+lenses+flashes+filters+...) I'm carrying around is worth about €5000, and I'm going to add a 6d+24-70tc totaling about €8000. I bought this gear piece by piece, but somehow it's grown to (for my standard) considerable value, though it's far from the pro 1dx/5d3+f2.8-kits other people have.

Starting as of today I somehow feel that not insuring the stuff but carrying around the greater part of it most of the time is not exactly clever, on the other hand my budget is stretched as it is so I'm wondering if other people insure their "midrange" dslr gear against theft & damage or they consider the real world risk too low to pay for the insurance?

EOS Bodies / Why's there 20mp on the 6d?
« on: February 11, 2013, 02:40:03 PM »
I am wondering why Canon put this sensor into 6d - the 5d3 seems to have the 22mp count because it's a multiple of 1080p and produces less moiré when downsizing to video resolution.

Is there any reason for the the way the 6d sensor is *except* marketing, i.e. keeping the tech spec even below the 5d2's 21mp? Maybe Canon gains a significant production advantage like less sensor waste for 6d and such is able to lower the price? Or is there any video- or stills-shooting related reason except that a little larger pixels produce a little less noise?

Lenses / How to reduce the nd filter warm color cast?
« on: February 10, 2013, 03:22:20 PM »
I'm about to buy the Heliopan 2093 nd filter with 3.0 density. The manufacturer states (German: http://www.heliopan.de/produkte/graufilter.shtml) that this density produces a warm color cast that can be removed by "adding a Heliopan UV/IR filter in front of the ND filter".

Now I'm confused: a) all I find are UV *or* IR filters, what is the manufacturer talking about and b) does this work & is it necessary or is it trivial to remove the warm color cast in postprocessing?

Thanks!
