Lenses / Re: Landscape Lens for Crop To Make Me Go Wow!
« on: Today at 08:05:56 AM »
Hi I used the EF-S 10-22 with my first digital camera, the 20D. It was a fantastic lens so I wonder why canon didn't put a red ring on it.

1. marketing
2. lack of weather sealing (which (afaik) all recent L lenses have)
3. probably general build quality, compare with the recent 16-35L.

That might be true in your case, but it doesn't mean it is universally true. Nailing every one of those 18 mp on your 60D with a 70-300 takes some doing. With really sound technique the only difference will be the amount of post shot magnification required.

I shot about 100k frames with my 70-300L on my 60d, so I guess some of them were in focus and without shake or motion blur, even if only by pure chance. And at least with my copy there's a distinct difference between f4 on crop vs. ff - that's why I mostly stepped down to f5.6 on the 60d. Here's exactly what I see:

Post Processing / Re: Assembling Portraits

Thanks for replying. It's always good to get an opinion of someone who has more knowledge.

Did I say that :-p ? Problem is that online, this is hard to verify if someone's talking off the top of his/her head.

In my case, I mostly do wildlife or pets+people, but I researched some into weddings and associated shooing situations - that's where I learned about the group portrait face exchange. But don't rely on that working, actually you want to have an assistant around watching out for drop shadows, occluded faces, bad hair, ... in case you're to busy with your gear to notice everything.

Lenses / Re: Landscape Lens for Crop To Make Me Go Wow!

ajfotofilmagem - 'Wow' as in image quality/sharpness. That's what I particularly noticed in using the 70-300L and the 50mm over the 18-135.

In that case, your personal "wow" is cheap to come by: The 70-300L is certainly a good lens and very sturdy, but on crop wide open it's noticeably less sharp than on full frame. So any half-decent midrange lenses should satisfy your needs.

I have to say that I am a little unsure about going the 10-22, 10-18 and 11-16 type focal lengths.

The problem with these uwa lenses on crop is that they're ef-s so you if you want to go ff in the future you either have to sell them or keep dual-using crop for ultra wide angle.

For ff upgrade safety, the new 16-35L with IS is a great choice as a wide-standard zoom on crop. Otherwise I'd personally have gon with the 11-16 lens if'd stayed with crop. Note that landscape doesn't necessarily mean uwa, and you can always panorama stitch if nothing is moving in the frame.

Technical Support / Re: 7D mark II battery drain
« on: Today at 06:54:44 AM »
Off should be OFF !

As I recently learned when my Yongnuo flash controller killed my batteries, off isn't off with most electronics.

It certainly isn't with your dslr. If you shot a lot of pictures and turn the camera "off", it continues to write the buffer to your memory card or you'd loose all these shots. With the 7d2/6d gps is another example that keeps on working and draining power even if your switch is set to "off".

I have no clue why the power to the lens isn't cut on "off" though, but let us know if you find out. Probably Tamron hasn't reverse-engineered the protocol and ignores the "camera is off" message from the camera to the lens.

If you feel that you need to hide the brand and quality of your equipment, then you are either doing photography in the wrong places, under the wrong conditions or using the wrong equipment.

There's a social component to it, too. A lot of rural people don't like rich saps coming from the big town, doing wildlife photography while walking all over the place. And yes, carrying €5000 camera gear qualifies as rich, no matter how objective that assessment is. The size of the gear is certainly noted, but making it look like working gear makes for a nicer conversation in my experience.

If Tamron wriggle about it saying the body must be at fault then my reply will be then why doesn't the 150-600 do it!

Last I remembered, Tamron service seems to be helpful exchanging a lens or updating the fw - and their repair time at least where I live is faster than Canon (w/o cps). It's just that they cannot test their lenses without access to camera bodies before official release.

I will submit these findings to both Canon and Tamron and see what they come up with.

Esp. the answer from Canon will be worth a snigger, if they reply at all to a 3rd party compatibility issue at all. Did you check you have a Tamron lens with the updated firmware? This information is around somewhere in the quoted threads, you can have a look at your serial number and compare.

No one has to read any thread, and it their choice to ignore the obvious, but sometimes you feel people should consult the topics list first before repeating the well covered topics.

With this kind of attitude, you'll get frantic around here :-p ... best practice is never to use the search box and start a "17-40L vs 16-35L" thread every full hour.

Most important, if you've got a question cross-post it to every photog forum on the internet, let lots of people try to give advice, and never get back to it ... which reminds me I didn't want to reply to 1st poster's posts anymore :-\ ... which doesn't mean this op won't respond, ymmv.

EOS Bodies - For Stills / Re: Is there any reason to shoot sRGB????

... for the real deal use Magic Lantern and the full raw histogram.
Gee, that's neat. Too bad the ML chaps stopped developing for the 30D.  :(

You're actually on a 30d as your only camera?! in that case, my "Mr. Budget" award passes from me to you.

I'm really not trying to offend you, and I'm sorry if some other thread mood spills over here.

1. the histogram is based on this setting, with adobe rgb you get a better representation
What histogram? Oh, you mean the one that the camera shows you AFTER you've taken the picture.
What histogram are you using?

2. in every cr2 there's a full jpeg thumbnail with the color space selected.
Of which the purpose is, beside for generating the utterly useless histogram?
It's extremely useful for quick sorting and browsing as a lot of software browsers use it - rendering the raw data takes a lot of time.

And in any case you should calibrate the monitor and use color management even with an srgb model.
So when will you pop over to calibrate my screen, before or after you calibrate every other computer and iPad screen on earth?
If you don't invest in a cheap monitor calibration tool, that's your bad, I waited too long until I finally discovered how essential this is.

A lot of browsers have built-in color management nowadays: IE, Firefox, Safari.
So what do these browsers do with an AdobeRGB photograph that is to be displayed on grandma's uncalibrated sRGB'ish monitor?
Obviously they display the photograph as srgb'sih if you set stock srgb in your browser and os color management. Are you sure you know how color management works :-o ?

Many better photo labs have printers that go beyond srgb
We don't have any of those around here ... just those KODAK self-service kiosks.
Ugh, time to move :-p ... where I live (Germany) most internet printing sites are wider gammut than srgb and also a lot of local print shops.

Ugh? How so?
Obviously, because the gamuts aren't the same.
To repeat your full statement: "AdobeRGB to sRGB conversion is never 100% successful because the gamuts aren't the same". When you read it, does that make sense to you?

In my experience colour management only works when you can control all the devices in the chain.

When you edit a shot and then print it, this includes two devices - your monitor (use a color calibration tool) and a printer (use a color calibration tool or the print shop's cms profile). Doesn't sound like rocket science, esp. with soft proofing in software like Lightroom.

In these case sRGB is the common language.

Under closer scrutiny, srgb is rather different between devices that claim to be srgb. Probably better than displaying adobergb or photopro, but still calibration and color management is essential unless you don't care about the accuracy.

very interesting, thank for info  :o

I only read about the histogram myself recently, but it's probably not that much of a difference - for the real deal use Magic Lantern and the full raw histogram.

he probably didn't mean conversion, but displaying Adobe RGB image in sRGB color space, to which some web pages are prone and then colors are shifted

Even so, I don't see why a properly set up color management (in your browser and/or os) wouldn't work - that's the very thing it's designed for. Sticking to srgb w/o color management might sound simple, but it isn't unless you're very careful to pick a monitor that happens to be 99,9% srgb.

If you photograph in RAW and obviously post-process, then the colour space setting in the camera is irrelevant.

Not quite:
1. the histogram is based on this setting, with adobe rgb you get a better representation
2. in every cr2 there's a full jpeg thumbnail with the color space selected.

However, if you photograph in JPEG (or RAW/JPEG) then sRGB is the more sound choice because your computer screen (and almost everyone else's screen) is set to sRGB.

Not quite: Wide gammut monitors have come down a lot in price recently. And in any case you should calibrate the monitor and use color management even with an srgb model.

The web runs on sRGB.

Not quite: A lot of browsers have built-in color management nowadays: IE, Firefox, Safari. But to be fair, this statement of yours was less wrong than the others :-p

Also your printer (and definitely the printer at the local photo-lab) prefers sRGB.

Not quite: Many better photo labs have printers that go beyond srgb

When an sRGB device encounters another colour space, it will usually convert said other colour space to sRGB. Conversion is never 100% successful.

Ugh? How so?

And now back to the normal yada yada "You're wrong, I'm right!"

Now, I don't think any female photogs would read a thread like this up to this point, probably it's easier for them to get a life - so I feel to make a visual comment of the proceedings :->

Lenses / Re: Lens as a gift. Non Photographer buying... :)
« on: November 25, 2014, 01:28:16 PM »
No offense to other posters but if you get a camera, avoid the 60D, get the 70D.  I own the 60D, 70D and 7D2 and the 60D sensor wasn't that great.  (Same sensor as the 7D.)  70D sensor is much better.  In fact, the entire camera works better including the handy touch screen, faster fps, better AF, etc.

The 60d sensor is a bit better than the 7d1 (less banding), but for the ergonomics alone it would be a great step up from an older Rebel if the budget is tight. But of course the 70d is a very good all-around choice as it's basically a downgraded 7d1. So when in doubt I'd rather go 60d+new lens like the bare 70d if the budget is maxed out for a while.

Yes, Sir, You are right on the target, Dear Teacher Mr. Mt Spokane.

Mr. Mt Spokane is indeed correct, and great shot Mr Surapon! I tried to do something like this with my 60d and the 100L (and 70-300L for comparison) lenses and failed miserably - you need at least a 7d-type af system for tracking insects in flight. With the 6d, obviously I wouldn't even try.
