Canon General / Re: Exif data, does it help, do you need it shown?
« on: July 23, 2014, 08:25:36 PM »
Just to add, some people strip out EXIF intentionally, some RAW converters have a tick box to remove it at export.  I store images in Aperture and add GPS data, which appears in the EXIF.  Time permitting, I remove it before export...but when I'm in a hurry, since I generally open the image in CS6 to reduce/sharpen, I just copy/paste the image into a new file.  That strips the GPS data (my intent), but also all the other metadata.

I usually post the EXIF for my images from Flickr, not usually for images attached to posts directly (hosted on CR). 

Note that for images with embedded EXIF metadata, you can copy the image URL (even for attached images), paste it into Jeffrey Friedl's EXIF viewer tool, and see the EXIF...it works on my iPhone, so it should work on your iPad...

85L II.  I have both that and the 135L, the 85 gets more use.  For use outdoors, consider a 3-stop ND – even 1/8000 s often isn't fast enough in bright light.

Build quality is inconsistent with the Rebel/xxxD line.

Because, there are survey results 4-5% of customers who bought the kit lens is that it does not use only kit lens.


Would indeed be interesting to see an accurate translation of this. Do 5% never buy another lens? If so that is an amazing stst

I could believe that easily 4-5% never buy another lens.  I know people with DSLRs that bought a kit and are just fine with their kit zoom.  They take pictures only once in a while such as on a trip or at some big event.  It just depends on how much they get into photography.

I sincerely doubt it means 4-5% don't buy lens(es) beyond the kit.  The lens + body sales milestones (100M lenses, 70M bodies) aren't consistent with that interpretation.

Unless those 4-5% are each buying multiple lenses. I mean, personally, I have purchased five different lenses than the 18-55mm lens that came with my original 450D kit. I know I'm not even remotely close to a "lens collector", as many people are.

Another thing I'd bet is, Canon only accounts for new lenses other than the kit bought. I am quite certain that more than 5% of DSLR buyers also buy other lenses, but I think there is a very significant market for used lenses. I'd be willing to bet that at least 30% of Canon DSLR owners buy another lens, and the majority of them buy one used.

Perhaps we're talking at cross purposes?  The statement that, "...easily 4-5% never buy another lens," is what I doubt.   The converse is that 95-96% do by additional lenses...that seems rather unlikely.

Anyone who's ever changed a litter box knows that cat litter is an excellent source of dust, and I'm not convinced that a few layers of paper towels will adequately seal in all that dust.  The silica or CaSO4 used in commercially available desiccant cartridges are crystalline and essentially dust free.

... Sunway Photo looooooooong plate running below the whole slider length (this is what made my choice, no other system has plates this long)

The longest plate/rail that I see from them is 300mm (~12").  If you need longer, RRS has 18" and 28" camera bars (CB-18 and -28).

Fine...but which lens was he talking about?  Perhaps the 'high resolution EOS' will be APS-C...

What are you trying to adapt/mount?

EOS Bodies / Re: 5d Mark III Misaligned Transmissive LCD
« on: July 22, 2014, 07:58:43 PM »
Liveview using live AF has no physical link to the AF points, it uses the sensor.  Liveview using Quick AF does use the AF sensor, but those points are electronically generated, and there is no physical connection or link to the AF sensor or the transmissive LCD.  Getting all three lined up does involve tolerances.

Presumably, the electronically generated AF point array shown on the main LCD during Live View Quick AF is 'ideal' – the center point is dead center on the image.  But the AF array on the transmissive LCD should be similarly centered, as should the actual AF sensor. 

That's three separate components, each of which must be properly aligned, and as you state they each have a manufacturing tolerance.  It would certainly be possible for two of the three to match and the third to be differently aligned.  Misalignment between the VF transmissive LCD and the 'ideal' display on the main LCD is easiest to detect (as in the OP's case), but if those two are aligned, the actual AF sensor could still be off...and that's more difficult to detect.  I have carefully tested my 1D X (specifically, I tested that the transmissive LCD was aligned with the actual AF points, in Live View I use contrast-detect AF – but the transmissive LCD also aligns with the 'ideal' main LCD).

I agree the AF array in the VF and on the main LCD for Quick View AF should be aligned, and your first image shows they aren't (on my 1D C they are perfectly aligned).  However, your test shots – particularly the graph paper – fail to convincingly demonstrate an issue.  Focusing on steeply-angled graph paper, like focusing on an angled ruler, is providing multiple appropriate focus targets at different depths...you may know which one you're trying to focus on, but the camera's AF system can't read your mind.  The girl's brow is a very low-contrast target.  Also, that may be an AFMA issue.

Check 3rd party focus screen options (although the screen on the 5DIII isn't considered user-replaceable by Canon).  Canon sells (sold?) screens with 4:5 and 5:7 aspect ratio masking.

EOS Bodies / Re: Eos7D mk2, How EXCITED will you be if . . .?

I'm sure mammals require more effort (staying downwind, etc), but I've never attempted to photograph them.

Mammals can be easy.  They let you get nice and close sometimes.  Just make sure any bunnies you try to take pictures aren't from Caerbannog...

It's just a rabbit!

Well, that's no ordinary rabbit!  That rabbit's got a vicious streak a mile wide!  It's a killer!
