+1 At least, they define it in their own minds. Some people have difficulty understanding (or accepting) basic facts...

Bangkok

As someone who just ended a photo trip in some rural and urban places where my gear was between 1 and 5 years of salary and the reputation sometimes very bad (Chongqing central station slums), I have to say I'm still a "member of the smile greet and act local" club.

My partner for the trip took the other way, he had a lomo for "hot spots" :D

motorsport photos

Thanks for the info. We have a local drag strip near me in Cincinnati, Ohio, USA. Oh how I wish it had a "bridge" overlooking the drag strip like the one in your photo. Very unique perspective, especially for drag racing.

This is in Puerto Rico, where there is plenty of rum and not much regard for safety. Not complaining, I pick up my photographers pass, and can kind of go where I want. My safety is up to me... I tried panning the cars at the finish line, and then realized 100-250mph hour cars are not the best panning subjects from 10 feet away. It is quite a rush when hey go by though.

One weird thing about the bridge is the cars move and there is no sound. The sound takes so long to arrive the cars have moved 10 feet, you have to watch the tree.

I do run a movie through my head of a guy getting taken out by an engine block in a drag race in the states, early 80s I think.

Choosing the right tripod

I am 5' 10" and a tiny bit, when my camera is mounted on a ballhead on the 055CXPRO3 with no column extension the viewfinder is 5' 4.5", it lines up perfectly with my eye when standing straight, no bending or stooping, obviously it depends entirely on how tall you are, how tall you camera and ballhead are etc. In the field I normally find myself not extending to max leg length anyway, I find it is a touch too tall to do fast panning and for landscapes and scenics it is generally much too tall.

As a good tripod recommendation, not too expensive, not throwaway, not likely to be outgrown quickly, hold its value well, the 055CXPRO3 is very difficult to not recommend. If mine got stolen tomorrow I'd buy another without question.

BlackMagic makes fun of Canon

In addition to the comparative images forged using different lighting (sunbeam in wooden furniture), the funniest part was professional connections: :P a micro HDMI, mini microphone jack, and mini-jack headphone. I laughed a lot. ;D ;D ;D Why so small as a toy? If I had a body like C100, and professional connections of fact, it could be taken seriously by many people with low budget. ;)

My new 600ex-rt seems to be 300K higher in color temperature (bluer)

Jim Saunders said:
Those numbers are for each of my three lights fired in ETTL at a piece of paper on the wall, with white balance drawn from the white panel on my WhiBal card using the tool in LR5; I should have specified. If you want I can try each of them at different power settings.

Jim

oic... thanks Jim for all the help! I think I have a bigger problem than that now...
My 600 is vy voltage sensitive with regard to recycling time.
Freshly charged Eneloop AA batteries give a recycling time of 2.4S when an eneloop
charged just 2 days ago gives > 3.2S! I think this is unacceptable and I am going to exchange my 600ex-rt.
Probably the color temp thing is related.

Thanks all for helping out! John

Horizontal Lines On Photos Taken Using Liveview on Canon 6D

Ok, didn't mean to upset anyone.
There's no need to be aggresive Lichtgestalt. I was simply excited to use the camera and after RTFM I confused that silly video/liveview option. No one forces you to answer a question you consider dumb. Just move along.
Thanks for the patience to the other forists though.
I got it now, thanks Dkocher for the advice! Everything's fixed and working great.
Appreciate your answers!!

focus-- 5diii

I have a 5D3 and I select an AF point closest to where I want to focus, back-button AF to lock and move to recompose then shoot.
This minimises the chance that re-composing would change the AF plane of focus.

Works well for me.

Also, I try and shoot portraits in the studio at f8 or f11 - nice sharp aperture for my lens and decent depth of field to work with too.

WEDDING PHOTOGRAPHERS 50mm 1.4 with close up filters vs dedicated macro???

Chris Geiger said:
To start with I don't like the 50mm 1.4 at all. When you are wide open it is very soft. No sharpness anywhere in the images. I had one for a time but sold it. I get much sharper results from my Sigma 85 1.4.

I think for closeup shots, the need to use it wide open would be very minimal, unless going for a really arty shot, where ultimate sharpness probably isn't important anyway.

Chris Geiger said:
As to macro lens or spacers I see opinions posted here with nothing to back it up. If your going to say that a macro is better, you need to say why it is better. Frankly I don't think it is better. Are your you going to get better depth of field with a macro lens? No, are you going to get a sharper image with a macro lens? No.

Actually, although I was suggesting extension tubes, logically, a macro lens should be sharper for closeups, as it the design is optimised for that short of work, while other primes have different compromises in thir designs. However, at teh size of images generally reproduced for weddings, the differences wouldn't really be noticeable, particularly as your average bride and groom won't be doing much pixel peeping. The question is more, "is the lens sharp enough?", not "which one is sharper?". I do have examples with my extension tubes, but not with the 50 f/1.4, so they wouldn't be of much use and for the small cost of a set of extensions tubes that could have other uses...

Chris Geiger said:
Are you really going to carry a macro lens around all day just to get a few ring shots? It takes me 30 seconds to set up a ring shot with an extension tube. I install the tube, crank up the ISO to 6400, turn the lens to F11, set manual focus and zoom my 24-70 to 70mm. Now I am ready to shoot macro and I did not have to go get a different lens.

I make use of my macro lens, but for occasional use, I would agree.

24mm TS-E II purple cast

GrgK said:
Thanks guys for sharing your experience. Today I had the opportunity to try the lens in a camera shop on a 600D and got the same results. The guy there also said this must be a factory defect. :'( I'll return this lens asap and try to put my hands on another one which does't have this issue.
Good luck! This is one of the most fun lenses I know, and the results can be stunning.

135L + 1.4x extender IQ question

I think you did the right thing, the 135mmL is wonderful, but not so much with extenders. I just checked, and of 5049 images with the 135mmL, I only have 3 with the 1.4X that I kept. I stopped using that combination when I did not get as good of results as I had hoped for. They are sharp in the center, but would not match the 70-200L MK II.

EF-M 18-55 closeup

ajfotofilmagem said:
Is possible, but... :-\ Buy multiple rings "step up" and use this huge hulk a small camera does not seem a good idea. Even as closeup filter robs image quality. :( See if you can find an extension tube for macro EOS M. ;)

A single step up ring can be had, but a 77mm closeup lens might be a bit heavy -

better choice is -

EOS-M extension tubes are available from at least a couple of vendors - for example

50mm 1.2

To all of those having difficulties focusing either the 50mm f1.2 or 85mm f1.2:
The prime reason for your issues with focusing is likely your camera body.

Use a 5D Mark III or 1-series body and you will be focusing just fine.

Using something like a 7D will make focusing at f1.2 somewhat of a challenge, even though its autofocus is generally quite good. I've been in that situation and after upgrading to my 1D-X + 5D Mark III combo focusing a wide open f1.2 lens is not an issue to me any longer. If you can focus reliably on f1.2 or f1.4 those prime lenses really do come into their own.

Best Super Telephoto Prime at reasonable price.. Any brand..

The latest (but discontinued) version of the Sigma 400mm f5.6 (must be the HSM APO version) works on some EOS bodies, and is very cheap, and well reviewed.

http://www.photozone.de/canon-eos/306-sigma-af-400mm-f56-hsm-apo-macro-test-report--review

I found one at ffordes.com and was able to try it on my 600D and 7D, the particular example wouldn't play nice with the 600D so it was a non-starter, try before you buy, but potentially a good buy.

Potentially a crap buy also of course, so check on both bodies.
