You're kidding me!!!  :o
Why not in the US?  :'(

Dunno... we're closer to Santa Claus?..

I'm thinking I get to test drive a 7d2 and 24-70/4 L lens then sell it off for a profit on eBay. :}

The 24-70 will be cheaper than their new standard zoom  :o
AND I get to keep the jacket!  ;)

@ JRista

Just updating a couple of your sensor rez data examples.

Present MFT is over 16MP.
E.g.  OMD EM10, 4640x3472 in 17.3x13.0mm sensor = 134.1 lp/mm
The more I use this camera, the more I'm impressed with it!  I can only imagine a FF with pixels like this. (~9650x6450)


A very good lens for the moment is the 75/1.8


that's at 60 and 20 lp/mm

or the Sigma 60mm Art for $210, fantastic, not even considering the price!




Nikon 1 v3/j4 is over 18MP
5248x3502 in 13.2x8.8mm sensor = 198.8 lp/mm

There's some very good glass available, one of them's the cheap 30-110mm kit lens, under $300. (80-270mm FF equiv)
MTF below:





and their 10-30 kit lens:






Oh, ya, and the Pentax Q7 is a mere
4000 x 3000 on a 7.4 x 5.6mm sensor = ~270 lp/mm
I've got one of these things too; can't say I've got a lens that can keep up to it tho, altho the 8.5mm f/1.8 prime is decent.
The only thing reducing the quality of the images from these little camera systems is the per-pixel noise as their full-well counts are so low that shot noise is an issue much sooner than with larger sensors.

Edit: tired fingers and brain. at least one type fixed

EOS Bodies / Re: How can we improve on 5D3 to 5D4?
« on: Today at 01:39:26 AM »
So... I'm just wondering how many here realize that the D810, D800, and D750 already have every single one of those features...
Perhaps just the few of us who've actually made the switch and learned what features our new toys, uhm, tools possess.
Frankly, many of those cool features I rarely have use for.  I merely moved to get much improved raw files for landscape work.
I do want to borrow a buddy's 150-600mm Tamron and try the D800's AF tracking for BiF shots.
I don't care if I don't have a high frame rate, just good focus.

And we all know Samsung has a huge selection of state of the art pro optics to mount on their Uber Camera....right?

Oh.......they don't?

uhmmm... give them a year or so.
They can move pretty quick when motivated and they'll likely want to put something out to attach to this new body.

Taking a hurried peak at a 7D2 RAW file, it seems like the gain vertical banding issue of the 7D may be entirely gone. Only took a very harried look though. It's hard to tell because the 7D2 has such a small black outer frame area in the RAW and I didn't have the program to check for the gain type in the mids and brights but it seems like it might be gone, none of the shots are close to lens cap shots, but there is a chance they got rid of all or nearly all of the offset banding at low ISO all together. So that is the very good and impressive news with possible both the 7D's weird vertical gain banding and the typical Canon offset dark shadow banding very low or gone, maybe.

The bad is that the random read noise still shows no improvements since 2007 whatsoever, as far as I can tell. It seems like it will be extremely close to the exact same DR as the 7D. The read noise might even be a touch higher than on the 7D. Not quite sure yet, didn't locate quite the proper 7D file or my old numbers. Without the banding, the effective usable DR should be higher though even though it seems like the engineering measured DR might be anywhere from a bit worse than the 7D to a trace better.

Holy cow, we're hoping!
at least we can deal with random-ish noise

This might be the first Canon crop body to break 70 on DxOmark score.

EDIT:  tho as a counterpoint, I've just been somewhat impressed with the tiny pixels in my Oly EM10 at iso 25600... score 72

Having seen the massive lenses produced for mirrorless cameras, I am beginning to question the whole point of trying to keep cameras small. This is particularly true when it comes to mirrorless cameras with crop sensors.

Olympus 40-150 f/2.8, Sony 70-200 f/4 OSS (for FE mount), Fujifilm 50-140 f/2.8, Samsung 50-150 f/2.8, Samsung 300 f/2.8 come to mind.

because if you want small lenses, they are available, and they're small.
Can't beat physics tho, bigger lenses do what only bigger lenses can do, with commensurate IQ results.

Listen to that shutter!  Wow!

Considering the very enticing pre-order deal on the 7d2, at least here in Canada, or Chinada since out PM just sold the place out from under us, I might order it, play with it, and still be able to sell it without losing anything but time if I don't like it.

EOS Bodies / Re: Official: Canon EOS 7D Mark II is not exciting enough
« on: September 15, 2014, 03:25:25 PM »
7d2 is pretty much as expected, AF and metering is skookum but no mention of any improvement in low ISO performance or any new tech to alleviate FPN issues which, more so with dual processors, can risk generating striped deep shadows as many 7d bodies did.
I'm not compelled to buy one at the intro price only to get some AF abilities my Nikon's already have an equivalent to and I seriously doubt it would satisfy my landscape requirements for the few shots I'd throw its way if I had it.  I don't do enough BiF or fast action shots for this to be a worthwhile buy.

Nope, sorry Canon, 7d2 isn't exciting me unless I see NO FPN when I test it.
I'll have to shoot some dark frames with it to see how noisy the output is but, for now, any cash I have is more likely to go to a new 44" Epson or HP printer (their inks seem to stick better) to help cash flow in.

Panasonic & Olympus have some exciting goodies coming out though, even Samsung's new mirrorless catches my attention.  Canon didn't innovate this year.

The Df with no Canon competitor?  Why should Canon bother competing with a camera that isn't selling?   ::)

HEHE.  Canon's retro look is hidden behind every one of their AA filters.

Third Party Manufacturers / Re: Nikon announced D750
« on: September 13, 2014, 02:14:28 AM »
..Let's think for a second: who will buy the D610 if they can pay a few hundred more for a D750?
I am more envious of the 20/1.8. I wish Canon made something like that...

I agree, there's currently not a lot of price difference from 610 to 750
with the 750's intro price that low, the don't have much room to lower it w-o first lowering the MSRP of the 610... That could be a good thing for someone considering the latter.

As for the 20/1.8... I'm salivating just thinking about it.
I use an old AIS MF 20/2.8 and an AI 20/3.5 and they're both very good, the 3.5 being very compact and light.
it there's slightly better corner sharpness with lower CA in this new lens, it will be very welcome

HAHA!  so a retailer messed up an important ad, that's gotta be a bit embarrassing
they did correct it quickly tho

www.adorama.com/alc/0014839/blogarticle/nikon-d750-full-frame-action-dslr-first-look

What about the real information on the D750 ?


$2300 intro price for the body
24MP
small light Carbon Fiber reinforced plastic body
Weather-sealing
wifi
D4s 51pt AF w 15x rated -3EV,
91k RGB meter sensor w 3d color matrix 3
6.5fps
3.2" RGBW tilt display
time lapse to 9999 frames
iso to 12800, exp to 51200
2x SD cards
pop-up flash w master
Dx (& other) crop modes,

1080 @60p to both SD or uncompressed to external recorder
stereo mic
headphone jack
zebra stripe
manual exp video changeable during shooting
flat mode for post grading


and the simple little SB-500 flash for only $250 w LED video light?

fast 20mm f/1.8G prime $800

These are all very appealing features/cost.

if they kit the 750 with the little 24-85mm they could likely list that around $2650, wicked kit!
happily, I still don't need one.

EOS Bodies / Re: Mirrorless vs DSLR Camera
« on: September 11, 2014, 02:54:59 AM »
I do not disagree.  In most types of challenging conditions I have more confidence in SLR AF for getting the shot too. In some others, the ML can actually do better.
A fast-paced and chaotic wedding is not the best place for a 'tog with slow gear.  Altho if you're old enough to have shot film and manual focus lenses, you might have to concede that today's ML can actually outperform most of those in most situations.  Last wedding I shot was a few years ago and slow enough of a pace that I didn't have to run very often and today's ML systems would have handled the whole day just fine.
So ML is not likely to be adopted en masse for wedding work just yet, not when SLRs are available and adequate and their users are more comfortable with them, but MLs are capable of delivering satisfactory results.  Some pro's are actually trying Fujis and other ML for weddings and doing OK with the change.
.
They're also a lot lighter, so could be easier to carry around all day as a few extra batteries they need don't weight all that much either. :>
I also don't have any need for the absolute biggest and brightest lenses as that super shallow DoF is not always desireable.
But BIGGER is usually more impressive to a north american audience. ;)

Lenses / Re: DXOMark Reviews Zeiss Otus 85mm f/1.4
« on: September 11, 2014, 12:03:17 AM »
I'd like to see Rodger Cicala run it thru his new test machine.  While I'm sure that the lens is absolutely a gem, there are always weak spots in a product due to tradeoffs involved in design and manufacturing.  Knowing what they are would be mostly out of my curiosity, since I won't buy one in any event.

Yes, altho this thing is PD sharp, I don't care for the swirly-circular bokeh in the background of some of those examples when it's wide open.  It does improve as it's stopped down.  This would not always be an issue but I don't like everything about how it renders OOF areas.
Give me the Samyang for $300 ! :)
