Lenses / 200 f/2.0 vs 70-200 f/2.8 II
« on: August 23, 2014, 02:55:12 PM »
Hello everyone,

I own the 70-200 II and I am mostly doing portraiture.
Does someone here own both and can upload some sample shots (wide open)? The question is if the bokeh and sharpness really is that much better (of course it is, but is it worth the serious amount of cash? How much is the difference really in IQ and bokeh?)

I also thought of getting the 300 2.8 (which would then be my longest lens), but it might really be a bit long for portraits.

Thanks to all of you helpful people  :)

Lighting / Elinchrom - turn off single flash
« on: June 26, 2014, 01:17:49 PM »
Hello everyone,

Is it possible to turn off one (or more) flash groups with the Elinchrom Skyport system while all other groups still fire?

Long version:
I do have multiple Canon 600 EX-RTs and the ST-E3-RT. Sometimes they just do not give me enough power when I want to light up a whole room (i shoot events every now and then).
My plan is to buy some Elinchrom flashes, place multiple lights in the room and to assign different groups to the flashes.
When I walk around during the event I'd like to turn off / on the flashes just as needed.

Is the Skyport system capable of doing this?

I'd also like to know if I can connect a Skyport universal trigger to the ST-E3-RT? I imagine carrying around the ST and adjusting the Speedlites  while adjusting the Elinchrom flashes with the Skyport.

Thanks everyone for your feedback!

Lighting / Lastolite Hotrod Octa / Striplight softboxes - are they good?
« on: January 16, 2014, 12:10:59 PM »
Hello CR users,

I'm looking for new softboxes to get more flexibility with my setup (4x 600EX-RT, already have some umbrellas and cheaper softboxes)

Did anyone try the Lastolite Hotrod Octa 36" (90cm) softbox or maybe owns it?
Did you like it? What were your experiences?

Same for their Hotrod Strip Softbox - is it any good?

Thanks for sharing your opinion / thoughts!

Software & Accessories / 32 bit HDR Panorama script / automation
« on: August 31, 2013, 04:58:29 PM »
tl;dr? Here is a short version:

I am looking for a way to automate the creation of 32 bit tiff HDRs so I can stitch them afterwards. I have Lightroom 5.2 and Photoshop CS6. It could be a command line tool as well (Linux-based would be ok as well). Any advice regarding LR and / or PS scripting would be much appreciated.

Long version:

Hello CR,

I hope to find good advice here - there are so many skilled people on this forum.

While I rather don't like the typical HDR look, I really like the natural look of 32 bit tiff HDRs. Basically these HDRs look like a regular image but you can push/pull the shadows/lights almost to infinity. This really helps me when I am in the mountains and the contrasts are just too intense.

I do shoot panoramas when I am at the mountain's summit. I know the regular way (create the HDRs and then stitch them) but this really takes a long time. Sometimes I have to create a HDR pano out of 150+ images. You can imagine that this really takes ages.

So my question is if somebody knows how I could automate the creation of the 32bit HDR tiffs? My current workflow is:
- mark the images in Lightroom 5.2 RC, right-click them and select 'create HDR Pro in Photoshop'
- files will then be opened in Photoshop CS6 and processed using 32 bit instead of the regular 8/16 bits
- save the file.

Instead, I'd like to see a button which would just create a 'default' 32 bit HDR.
PS should automatically open, process the image and save it without any popups or questions. I know PS has some scripting abilities, but a command-line tool or similar would be fine as well. The perfect setup would be
- specifying how much images per HDR in a popup (2,3,5,7, etc) so that the script can automatically create all HDRs (file names contain ascending numbers so it should be possible with a good script)
- use PS to stitch them automatically afterwards, as most of the time the stitching from PS is okay if you used a nodal slide etc.

Thanks for reading all this, I'd be glad if you had some advice how to speed up my workflow here. If you have a better idea than my current workflow or if you can point me to a PS or LR scripting tutorial, please let me know.

Software & Accessories / Smartphone with IR-Diode - Remote trigger?
« on: May 10, 2013, 08:40:30 PM »

I recently got the new Galaxy S4 which features an infrared diode. As other new smartphones come along with IR diodes I was wondering if somebody knows an application which would turn these IR diodes into a remote trigger for our beloved cameras?
I tried 'DSLR Remote' which makes use of external diodes, but it did not work with my 5D3. I mean, I can control my whole TV and Bluray player setup using just the phone, so it must be possible somehow?

Btw, I can recommend the application 'DSLR Controller' made by Chainfire - it requires an USB cable but has some nice functionality like automatic focus stacking, time lapse and so on.

I'd be glad to hear about your opinions regarding the IR diode - maybe there is an Android developer among us?

Third Party Manufacturers / [advice] My last tripod
« on: May 08, 2013, 11:46:35 AM »
Hello CR,

I am quite satisfied with my current gear (5D3, several L's) but I am lacking a good tripod.
I used my father's old tripod for a long time because of sentimental reasons (I mean, it's my father's tripod!).

However, I have a feeling it is about time to upgrade.
Budget is not really an issue - I prefer buying once over buying something cheap(er) and being not satisfied afterwards. Eventually you'll end up buying two times.

Main use will be landscapes (85%) and cars or other static objects.
Heaviest gear combination will be my 5D3+70-200 2.8 II or 5D3+100-400 (although the 16-35 and 24-70 will certainly be used much more often). I am 196 cm tall (I guess that is 6.43 feet? Quite tall). Stability is more important for me than transportability. I do use Arca-style RRS plates on all my gear (I use my Gitzo monopod very much, hence the plates)

What do you think of the RRS BH-55 as a head and the Gitzo GT3542LOS or GT3532LS as a tripod? Is it way too much for my needs? I'd prefer a 3-section tripod over the 4-section series, but there unfortunately is no 3-section ocean series from Gitzo.

I highly value your opinions and would appreciate if you share your thoughts. Thanks in advance!

tl;dr? Here is a short summary:

Tripod + head in need,
- stability > transportability
- budget: not a real issue
- main use: landscape and other stills
- I am 196cm tall (6.43 feet)
- Arca plates
- Heaviest combination: 5D3+70-200 2.8 II or 5D3+100-400 (although the 16-35 and 24-70 will certainly be used much more often)
- I am a bit RRS / Gitzo focused, but other opinions are still very welcome

Lenses / USB Dock of Sigma 35mm F1.4 DG HSM
« on: March 28, 2013, 08:43:42 AM »

I read that the new Sigma Art-Line 35mm F1.4 DG HSM is delivered with a software which would allow to setup the AF similar to AFMA - how does this exactly work?
Is it better / worse compared to just using the camera's AFMA?
Does that USB dock software for the Sigma work with softwares like Reikan FoCal?

I'd be glad to hear your experiences and knowledge.

Lenses / 24-70 2.8 or 24-70 4.0 IS ?
« on: March 25, 2013, 06:13:15 AM »

I am intending to buy a new 24-70 so I was wondering if the EF 24-70mm f/2.8L II USM has a better IQ than the EF 24-70mm f/4L IS USM ? I would pair it with a 5D3.

I saw some very good reviews of the 2.8 II, but the 4 stop IS of the 4.0 sounds tempting...
I'd be glad to hear your opinions on what to buy.
Thanks in advance!

Software & Accessories / Help on interpreting FoCal results
« on: March 13, 2013, 07:43:22 PM »

I just tried Reikan FoCal with some of my lenses and I am unsure on how to interpret the results.
To me it seems like my 5D3 has issues in general (meaning if I focus on a matchstick it is OOF as it focusses a little bit in direction of the camera, if I get it right?). The last column shows the average adjustment. Would you set it to the average or shall I take the distance in which I use the lenses most?
Shall I send the camera and lenses in and if I do so, will they charge me? The camera and lenses should still be covered by warranty. Does the warranty cover adjustments?

Your thoughts and help are much appreciated!

EOS Bodies - For Stills / 5D3 AF Guide - slightly wrong information
« on: February 28, 2013, 04:40:12 PM »

this is my first post so please forgive me if I posted in the wrong section or if I did anything else wrong.

I just googled "5d mark iii instantly recalled af point" and google came up with http://cpn.canon-europe.com/files/education/technical/inside_canon_eos_5d_mark_iii/EOS_5D_Mark_III_AF_setting_guidebook.pdf which reminded me of the 1DX AF guide.

In the 1DX guide they write "Press the 'AF-point-selection-button-symbol' button while pressing the ISO button until you hear a beep" - this never worked for me and I was really disappointed as I thought the 5D3 and 1DX AF systems were the same. The functionality would be soooo cool!

In the 5D3 guide they write the same, but the picture is showing the light bulb for the top LCD. I did what they wrote, but it did not work. Disappointed again. But after some experiments I finally got it to work!
The solution is: Press the AF-point-selection-button and hold it, then just press the top LCD light bulb button just once. Done!

Now I finally can switch instantly between my most used AF points.

I hope you find this useful and sorry if this had been mentioned earlier. I really like this forum and already learned a lot from you all so I thought it is about time to give you something back.
