Lenses / Re: Another standard zoom advice topic
« on: August 28, 2014, 09:41:54 AM »
The Macro function is a gimic as you have to be so close to the subject your most likely to scare it away

I haven't managed to scare away a flower, coin, or textile yet...if they run from you, it's likely they're scared of you and not the lens!   ;)

IMO, the issue with the close working distance is the lens blocking the light, which is already effectively reduced at higher mag.

Wrong.  I went full-frame, and I kept my APS-c camera for its advantages in high pixel density and fast frame rates over the full-frame.

Of course, the latter is not a general 'crop factor advantage'.  You can get higher frame rates for lower cost, and as I've stated, lower cost is the main advantage of crop sensors.

EOS Bodies / Re: ISO 50
« on: August 28, 2014, 09:09:14 AM »
ISO 50 is a full stop less than ISO 100.  On the 5DIII set to ISO 50, the camera is exposing at ISO 100 then pulling the exposure a stop digitally, so you're really not gaining anything.

I have many, actually, it's just that they were controlled tests, rather than uncontrolled tests.  You see, to science folks like myself, uncontrolled tests are useless.

More detail, yes.  Just not as much extra detail as you'd expect from the difference in pixel density, even in controlled testing.

How do those touting Exmor advantages demonstrate them?  They underexpose by 4-5 stops then push the shadows back up.  While there are valid reasons to do that, it's an 'advantage' that's totally useless to the vast majority of dSLR buyers.

A lot of people do just that, yes. However, I have been showing examples where underexposing was a necessity. I'm an "afternoon landscaper"...I can never get up early enough in the morning (which is really early, like 3:30am), in order to be able to drive out to the kinds of beautiful landscapes I want to photograph, but get there in time to set up and be ready to go by the time the rising sun lights the clouds afire with color.

So, I'm stuck taking my photos in the afternoon, when the setting sun washes the clouds in color. Problem is, all the mountains are to my west, same direction as the sun.

As I stated, there are valid reasons, albeit very rare ones.  In your case, not strictly a necessity, since you could get up at 3:30a but don't want to.   :P

Consider the USA – what states are immediately to the east of large mountain ranges?  Yours, Nevada, etc.  Tiny fraction of the US population, so even if there are the same per capita number of landscape shooters, that's not many people. 

That's really the whole point here...the number of people who require (or believe they require) that kind of shadow lifting capability is minuscule relative to the dSLR market.

Most everything I shoot is moving - fast.  How would you suggest I shoot identical shots with two cameras of the same subject? 

Auto racing, standing at a turn with cars coming toward you.  500 chances to shoot the same car going around the track...   ;)

True. Most people buy iPads and iPhones to shoot with.  So I guess that makes them superior cameras to Canon DSLR's?

If it does, then Canon's dSLRs are superior among all other dSLRs.

I'm not really interested in who sells the most...

The topic of the thread is, "Do Sensors sell the Camera?"  The answer is, in general, no.

All of this Sensor Hype is probably meaningless to that crowd as well just the same as it is to 90% of those buying Sony and Nikon equipment.  If this were all that important, Nikon cameras would be selling a lot better than Canon and that is not what we really see.

The problem with that comparison is you use the sensor every single time you take a photo, and not "the system".

Which is exactly the point.  You use the sensor every time you take a shot, so if Canon sensors were so inferior, Canon would not have remained the market leader.

EOS Bodies / Re: MISSING Camera body feature

On the 1D X, if you're willing to give up the AE Lock button, you can assign that to back button Servo with AF-ON as back button One Shot, or vice versa.

41
This gives R for 7D/5DIII = 1.19.

So, the effective extra reach is 19%. (Based on the ratio of their pixel sizes, a value of 45% is expected).

That might be true in a testing scenario, but few of us shoot in those. Factor in AF, handholding, higher than base iso, less than ideal aperture or shutter speed etc etc etc and the differences become minimal, as so many people who have owned both have attested to.

As I've stated, the most significant advantage to APS-C is lower cost.

I'm pretty certain I'll never buy another DSLR.

I'm pretty certain I won't buy another dSLR until the 1D X Mark II comes out...   :)

Software & Accessories / Re: Canon brand UV and Circ. Polarizing filters
« on: August 27, 2014, 11:29:30 AM »
Clear = Neutral, exactly what you want from a protective filter (unlike UV, which can affect color balance adversely)

Can I ask… Do you have empirical evidence for that adverse effect, or are you basing the suggestion on the <5% loss of transmission in a ~25nm region of the spectrum where the sensor is at <20% of its maximum sensitivity?

Bullet dodged...maybe.  All water has mineral content, water + minerals + metal = corrosion.  Ever see a little spot of rust on metal?  A few week/months later, it's a much bigger spot.  Corrosion is like that.  Unfortunately, that often happens after internal water in electronics.  It dries out, the device works.  Corrosion slowly spreads unseen, and a few days/weeks/months later, it dies for good.  I suspect that's why Canon said not repairable – they can't stand by any repair short of complete internal replacement, costing more than new ones. 

>$4K loss is unfortunate.  That sort of possibility is why I have my gear insured, something you might want to consider.

I have a 1D X for quality and an EOS M for convenience.  No plans to compromise on both.
