EOS Bodies / Re: So I made the jump to FF - now what?
« on: July 08, 2013, 01:53:52 AM »
If you're used to the long reach of a crop, and you're certainly you'll make use of it, the 70-300L is a superb lens.

(truth be told, however, I would wait a bit and see if you don't find that cropping images from your 24-105 isn't just as suitable - when I upgraded to the 5D3 I bought the 70-300L since I was so used to the 320mm equivalent on my 50D, yet I use it very little - I can usually just crop the long end of my 24-105)

I would also recommend the shorty 40.  Very inexpensive, the IQ is amazing, and it's very convenient for those times you want to be subtle.

while people are pointing out that "why would he openly wear the strap of an unannounced camera", note that he is wearing the strap "upside down", with the lettering turned in. it is only because it is half twisted in this side on view that we can see it.

i.e the strap is being very deliberately worn in a non-traditional manner.

Perhaps a better question would be "why does anyone use the supplied strap anyway?"

They're awful (uncomfortable and too slippery), they advertise "steal me" to nere-do-wells, and they're difficult to install.

I recommend a nice neoprene strap (I like Optech but there are plenty of other options) and a C-Loop from Custom SLR.

Mine should be here on Monday.

I'm looking forward to 'hacking' this camera.  It seems to offer lots of possibilities given the availability of many different lens adapters (far more than the regular EF mount permits, since the M has a much shorter focal plane distance than most anything else).

But I wonder whether this means Canon plans a new model, or are they giving up on the M format?  This being Canon RUMORS, has anyone heard anything?

Do I need to panic and rush to get the EF adapter now (perhaps with them disappearing like the very rare FD-EF they made briefly for the pros), or can I wait a few weeks?  That sort of question.

Maybe this is the camera to perform the Bayer Filter removal and conversion to high resolution B+W only?

I'm thinking sell the 22mm lens, use the proceeds to (mostly) pay for an IR conversion.

I've got plenty of other lenses.

Software & Accessories / Re: Camera RAW

Allow me to second MrFotoFool's position.

From what you've written, I would recommend you stay away from RAW until you've really nailed composition, exposure, and white balance.

The purpose of RAW is to provide the best (raw) material for post processing (Photoshop, Lightroom, etc).  Which means you need an additional set of skills to achieve anything worthwhile.  On the other hand, if you have great composition, exposure, and white balance, there is little to no need for post processing.

Once you've really mastered the basics, you'll be able to get something out of post processing if you want to explore that route.  Until then, all it will do is frustrate you and distract you from the real goal, great images.

Maybe it is because I've been doing this for over 40 years, and still have a film based philosophy, but I find no enjoyment in post processing.  So I strive to get the best possible results out of the camera so I don't have to sit in front of the computer for hours.

EOS Bodies / Re: Is This the EOS 3D?

Perhaps that is an EOS-3eye strap, dating back to the film camera.

I just hope that when Canon finally comes out with the 3D, it really is 3-D (they can then sell you two L lenses at a time instead of one).

Software & Accessories / Re: Right Angle Finder
« on: June 22, 2013, 09:49:03 PM »
I have an Angle Finder B (which fits the 5D3 perfectly), and I have been very pleased with it for low (and high) angle shots.

The B can be had on eBay very cheaply (got mine NIB for $20), because most people apparently don't know that it fits the new cameras.

EOS Bodies / Re: Moire in the 1DX and 5D3
« on: June 19, 2013, 09:39:35 PM »
Its a side effect that appears as you get higher frequencies in the image.   Unfortunately, once its captured, it can be reduced but not eliminated.
 
The part the lens plays is in delivering high resolution that lets the fine detail be projected on the sensor.  Stopping way down filters out the moirĂ© by reducing resolution.

Thank you very much for pointing me to that explanation.  I get the picture now (sorry, couldn't resist).

The lens is oversampling the sensor.


I'm afraid I don't understand this statement.  A lens is an analog device; I don't see how it can "sample" anything.

Ideally, it provides a perfect image focused upon the sensor - that's the goal, is it not?  At worst, the image has lost some resolution, and perhaps has some aberrations introduced.  But moire isn't either of these two effects.  As the respondent below pointed out, you never see this sort of thing with film (an analog media).

So I would assume it is a byproduct of the way the system samples the sensor array and merges the four color pixels into one.  But the lens has nothing to do with that, unless you are suggesting that there is something inherent to the performance of the lens that causes this effect when the sensor samples.

Would you please explain this (or point me to a reference that does)?

Thank you.

And someone was speculating about 102k native ISO. Would be great! Waiting for that. Maybe in about 6 years from now via the 5DV? 102 k like my 25k on the 5D3...wow.   8)

That was me; high ISO was why I bought the 5D3 (the 1DX was out of scope both due to money and physical size), and I really look forward to the next improvement in the ISO department.  Rather like the jump from pushed Tri-X at 1600 to 2475 Recording Film pushed to 6400 and IR film with a filtered flash; there is no going back.

Having always been an 'available light' photographer, complete with the limitations that implied in the past, I am loving the stuff I get from the 5D3.  But of course I want 'more', and I know it's coming.

After all, that's how these suppliers of photographic crack stay in business.

Re: What would you do if you had $2000, a 5DII and no lenses?

Be both very sad and very excited?  After all, a body without a lens is like frying pan without a stove.  It may have some alternative use, but for its main purpose in life...

I would buy a 24-105L, put the remaining $1300 in the bank, and start taking pictures.  After say 6 months, you'll know if you need for your next lens to be a telephoto lens or a wide angle one.

If you need a wide one, buy the 17-40L, and you'll still have $600 for something else.  If you need a longer one, I'd recommend the 70-300L IS, which will be about it (you might even need a few dollars more).

As I've posted before, my order of priority was:

24-105L
70-300L
40 pancake
50 f1.4 Zeiss

and next on the agenda is either the 17-40L or the 16-35L MkII, then a 100 macro L

But that's just me  :)

Either 34.56mp (4800x7200) or 56.62mp (6144x9216; extra credit for seeing why I chose the latter numbers).

1920*3=5760

5760*1.6(crop)=9216

So it's the same pixel density as a 1.6 crop sensor with three horizontal pixels per output horizontal pixel in full HD video mode.

Fascinating.  That was not what I was looking at at all.

I was thinking 256 pixels per mm (vice 200 pixels per mm for the 7200).  I like your answer better.  Well done.

OK, if they really want to impress everyone:

Either 34.56mp (4800x7200) or 56.62mp (6144x9216; extra credit for seeing why I chose the latter numbers).

ISO native to 102K (H2 is 408K); 12fps (24fps with the optional pellical mirror); Dual or Triple DIGIC 6 as required; high speed video mode (640x480 at 4800 fps).

Modified 1D body with dual battery compartments and built in thermoelectric cooler.

Less than 1 million yen.

I'd save up for that.

If they build it as a mirrorless at 750K yen, I might think about it.  And make those Leica folks jealous.

My Impression was $$,$$$
Sounds impressive though.  The tube shape might be optimal for cooling.

No, just $,$$$ :-)

If they are consistent, it will be between $3,000 and $4,000.

I wonder if this is the first product that will be made in Foxconn's new Detroit factory?

Seems like this would be fairly straightforward.

With the 5D3, one can take a still while shooting video.  I don't believe the shutter curtains move during this (I just tried it, and while watching through the lens saw no movement), so it would seem the camera uses an electronic shutter in that mode of operation.

All that would be required would be to actuate the hot shoe.

And that would be very useful indeed.
