I hope I'm not high jacking this thread ... It's gone way too scientific for me to comprehend fully despite trawling tHrough the posts.

Would it be a reasonable conclusion to draw that at low ISO (100-400), the difference between the APS-C and the FF is negligible, thereby meaning that the reach benefit could be satisfactorily obtained at the low ISOs?

There is always a difference. It may only be negligible for those who don't care.

Thanks. What differences would be obvious and what would be the ones you would look for? Again, I'm talking only of low ISO.

Good to hear a sane voice. I'm tired of people telling me how bad my gear is. 

EOS Bodies / Re: 7D2 and EF 24 - 105 F4 L IS USM

Why not get the 17-55? Used, if possible. This lens retains substantial value and is excellent for shooting on the APS-C.

The 24-105 on an APS-C is an oddball focal length and it is f/4 as well. The one stop ISO penalty is pretty heavy - I'm thinking of the difference between ISO 3200 and 1600 and then between 1600 and 800.

I'm excited about the 7DII for the AF and the 10fps. if Canon has taken care of the banding, I'm getting one.

Oh, and here's yet another wedding image I was processing from my 5D3 that I decided to throw out b/c by the time I corrected the 3EV vignetting of my 24/1.4 and then added 1.5 stops (b/c I underexposed by 1.5 EV to save the sky/clouds above my subjects), I had this wonder junk overlaid over my image

Maybe you should learn to convert and process your files properly.

I always thought wedding photographers make use of reflectors to avoid such classic lighting problems? That was what my wedding photographer did to get a beautifully exposed shot with the sunburst and blue sky behind us. Oh, he was using the Canon 5D classic.

Oh, here is another example: Matt has mostly Nikon gear.  ;)

You are absolutely right, except that generally those here suggesting the Exmor tech can do a better job don't want to be bothered with fill, they want to be able to use every ounce of the extensive latitude in the Nikon file.

They will of course will be lifting data that has recorded virtually no light, so the photographer using 'old' tech such as a 5D or D200 and sound technique will produce a much higher quality image.

So what happens if you use sound technique with both Canon and Nikon ? You get pretty much the same image. A well lit and correctly exposed image will always triumph over the same one which has been poorly lit and under exposed.

Sensible post alert! You talk too much sense Sporgon and it's not likely to go down well with the ABC crowd.

Photography is all about light and handling thereof. Light is "lightly" tossed aside by the people giving examples of the benefits of an exxmor sensor.

I can understand someone complaining about DR for landscapes (not taking into account that DR in most landscapes will exceed even the what the exxmor provides). But why someone shooting in a controlled environment should complain about DR is beyond comprehension.

EOS Bodies - For Stills / Re: POLL: What's more important, gps or wifi?
« on: September 19, 2014, 08:27:34 AM »
Being a hobbyist, I've used WiFi considerably on the 6D instead of the GPS. Too many of my family and friends want their photos ASAP and the 6D with the EOS-Remote has been upto scratch for this purpose.

The GPS has come in handy a few times I was shooting out in the wild, but WiFi has been more useful to me.

Lenses / Re: Lens price drops around the world
« on: September 09, 2014, 10:55:21 PM »
From what i am hearing, it is US only...  but other countries have dropped a bit.  I just hope that it drops a bit here in India...  I've been saving a long time for my 500 f/4 and would be miffed to buy and then it loose value right away!

Canon India did drop prices a couple of months back. The lenses included in the recent drop were 180 macro, 70-200 II, both L TSEs, 85L and the 300 2.8 II L. The price drop was quite steep, approximately 14% or so.

The superteles. Including the 500 II are already reasonably priced in India. The 500 II can be got for INR 550K. This is slightly less than, or roughly equal to the US price which I believe, underwent a drop recently.

Photography Technique / Re: Focus problem with 100mm
« on: September 09, 2014, 10:47:15 PM »

I purchased Focal. I have Magic Lantern on my 5D3 but have not tried dot tune.

Hope this helps... Let me know if you have any questions.

Hi rpt,

I've tried dot-tune but the results were too variable and unreliable for me. Ever since purchasing Focal, I haven't looked back.

In the absence of Focal, manual empirical testing with different AFMA values is the best solution in my opinion. But it isn't easy to identify the sharp/sharper/sharpest photos using this method.

Lenses / Re: When will we see a replacement for the 100-400?
« on: September 09, 2014, 10:40:01 PM »
I doubt that the replacement is coming anytime soon.

The tammy 150-600 has upped the ante with better than reasonable IQ at a good price point. Sigma is hot on the heels with its own super zoom.

A Canon mark II with less than stellar IQ will be beaten by the super zooms on focal length and price. A Canon mark II with stellar IQ risks cannibalising Canon's own super telephotos. It is my opinion that Canon is caught in a bind and doing nothing makes most sense.

India / Indian subcontinent not mentioned.

Face it, India is a *sub*continent so you belong to Asia even if your very own tectonic plate crashed into it some time ago :-). But Asia is really missing, probably that's why our well-known Japanese contributor didn't participate?

Ouch! I meant to write Asia and Indian sub-continent (which has more countries than just India). Visiting these forums in a sleep deprived state last night wasn't such a good idea. I'm happy that good sense prevailed :)

That said, clubbing Everything to "Asia" is unwieldy because of the sheer amount of area involved and the demographics. China and India contribute to over 38% of world population.

India / Indian subcontinent not mentioned.

Boo! Hiss!

EOS Bodies / Re: Mirrorless vs DSLR Camera
« on: September 08, 2014, 09:22:55 PM »

I imagine that anyone who makes a living out of photography is going to have a few more than one camera body. So service time should not be a factor.

Good point. So when my 70-200 II took a jarring knock last month resulting in the elements going out of alignment, what should I have done? simply reach out for my back up 70-200 II :o

BTW, CPS returned my lens in perfect working condition within 24 hours.

Photography Technique / Re: Step Wedge?

The only use for a step wedge in digital is empirically testing the DR of your camera.

Ugh ... Us Canon shooters don't need one, we are well aware that the DR of our cameras suck!  :-X

Thanks for the replies. Having read about them, I'm not entirely sure where they figure in digital photography. In case anyone has found any use for them in digital photography, please share your experience.
