EOS Bodies - For Stills / Re: 5Ds or possible alternatives?
« on: Today at 03:17:09 PM »
Alternatives: Canon 5Ds (5DsR), Sony A7R (or mark II if it comes out), and Nikon 810.

Well, I can say that a friend of mine who broke his 5d2 due to the non-existent weather sealing just purchased a used d800 on my advice. I begin to regret this because....

... now I'm getting daily enthusiastic mails from him, wishing his Canon would have been broken earlier to force him to switch. Admittedly he's a landscape and high-dynamic range guy, but for that application the 36mp 14+ ev Nikon sensor blows Canon out of the water. I don't think the studio "crop upscaled" 5ds is a competition here.

DR: Expose correctly, capture in RAW/CR2. It is extremely rare that this does not do the job. If not, it's HDR time

*Snigger* oh my it's Canon enthusiast time, but really, try that on moving cloud with light beams shining through them and people walking about the scenery. Or anything that moves in high contrast like leaves or grass, actually.

Don't misunderstand me please, I'm happy you're happy with Canon and totally love my Canon gear, but as far as landscape as dr is concerned you cannot just compensate with bracketing even if you accept the usability hassle.

Lenses / Re: why isn't the 17-85mm gone ?
« on: Today at 03:09:11 PM »
That is odd.  The 15-85 blows away the 17-85, and isn't that much more, I'm blown away the 17-85 wasn't disco'd.  I was under the impression it had been.

Canon doesn't seem to actively discontinue lenses unless absolutely no one is buying them anymore and they have run out of stock worldwide. It is indeed odd, but it seems the way their production works it doesn't hurt them to have legacy lenses in the lineup that no one seems to be buying (50mm macro anyone?).

How do you know? Got any solid evidence the cross types of the 7D II is better than nikon non cross types when shooting anything other than bar codes?

Take it from me, after shooting with a non-cross single af point film camera for a decade and now being burdened with the 6d's af system I feel safe to say that the difference is *huge* unless you have the time and patience to select a pattern that happens to match the non-cross point you have selected :-\

But what would you be shooting when the light levels are at -3EV?

This isn't that dark if you use a slow lens or a tc and end up at f8 (if the d7200 can do af at f8, I didn't check). With the latest IS systems, you can still handhold these indoor shots.

Very Meh compared to the 7D2 but a relative competition to the 70D.

Sure, but I don't think it's meant to be a 7d2 killer. Nikon is probably quite content to leave the premium and niche market to Canon while grabbing the mass market with better value, i.e. more features for the same price or the same performance for less €€€.

I'm sure there'll be pages over pages on Nikon service, oil leaks and whatnot - but imho even Canon fanbois might have to ack that Nikon is damn competitive with these crop cameras ... esp. as the 70d doesn't even run Magic Lantern too extend features and boost dynamic range.

After all, we Canon shooters should be happy for a strong competition, or the 70d would still have 9 af points and the 7d2 would have a €3000 price tag :-)

Abstract / Re: 7D2 HDR - Mustard Yellow!

What was the thinking behind the selling the D750 for a 7D MkII?
The D750 was the last straw in a 45 year Nikon adventure.

Welcome. And .... remarkable! One soul freed from the clutches of the evil Sonikon empire will brighten the spirits of the dr-depressed crowd over here. Canon should have you stuffed and on display in their marketing department :->

I do hope the 7d2 works out for you, Canon has great usability, good lenses (if you happen to be able to afford their top realm gear) and reliable service (if you have premium cps membership). But of course the 7d2 is a crop that will have different sensor characteristics from a full frame Sonikon - though no doubt you knew about that.

If anyone offered me the choice of a D750 vs a 7D-II, I'd definitely go for the D750.

See, FFN? Here's proper Canon shooter :-p ... and personally, I'd make the same decision esp. as the 7d2 doesn't run Magic Lantern.

by hooking your little finger onto the stick.

I'd love to the a picture of *that* :->

I may try the string technique too - string attaches to the 1/4" tripod hole in the bottom of the camera, stand on string, pull upward.

This one is rather ingenious as the equipment needs zero packing space. I wonder how many stops this axes off the shutter on average vs controlled breathing alone?

Lenses / Re: Canon ef-s 17-55mm 2.8 is usm GONE
« on: Today at 12:32:42 PM »
Has anybody seen that the 17-55 is completely gone from the product page from canon usa? I noticed yesterday that the price was missing and if you clicked on it that you got redirected to the home page. Now it's completely missing from their product page.
These things happen from time to time.

Good thing that, what would be a rumor site w/o these "xyz has disappeared from abc" threads? :-p

In theory, it's quite possible to merge several raw files into another raw file, Magic Lantern does it for their dual_iso feature.
That's not how dual-iso works. Dual iso changes the iso line-by-line when reading out the sensor so it's a single exposure. You do need a post processing tool (cr2hdr) to extrapolate the values to smooth the transitions. Otherwise you end up with a picture that looks interlaced due to difference in exposure between the lines. People are using dual-iso because it's a single exposure and not a post bracketing merge or several photos. I use it for handheld 1:1 macro pictures to avoid blown highlights when using a flash and 1/400s shutter speed.

Right, I faintly remember someone else mentioning ML and dual_iso on CR before now and again :-)

My point is that dual_iso outputs a raw file, and not a demosaiced jpeg or whatever. It's true that dual_iso is based on interlacing rather than stacking exposures, but I don't see any reason why it shouldn't be possible to hdr-merge several raw files into another raw. It's not like the raw data is a black box as oss software raw converters exist. My guess it's that simply no one has found it worth the hassle - or there are problems I cannot think of right now.

look at ground glass

You're right, this is an alternative, I nearly forgot about it. I use it to shoot macros of frog eyes as the dof is so tiny the af will never work. Imho it really depends on the vf size, for example I find it easier with my 6d than 60d. And for anything with less magnification, arguably af works better the larger the distance gets.

Another drawback of the fixed focus approach that you have to move the camera back and forth, this can be a problem if you're lying in the ground or standing waist-high in water and would rather keep a stable position :-).

Didn't he use NIKON by the way....?!  :o

Logic dictates to use the camera system with the most features for a given price and the highest dynamic range (proudly being the first one to bring this up) :->

EOS Bodies / Re: EOS 6D Mark II to Move Upmarket? [CR1]
« on: March 01, 2015, 12:04:06 AM »
The recently announced 750D & 760D have 19 AF points 11

A crop rebel is hardly a competition for a ff camera ...

in the 6D is indefensible as is 100,000 shutter count when the 5DS and 5DS R have moved to 200,000.

... and this number has a lot of marketing to it, you only know how durable the shutter really is after years of usage by lots of people or getting inside knowledge from Canon r&d.

Double card slots is not a selling point for me, but then I am not earning my living through photography.

It's like an insurance, you only value it if you've lose one or several day's worth of great pictures, so imho it has its place in an "non-pro" camera, too, as the sd slot doesn't take a lot of space. But of course Canon did it to make the 6d more awkward to use for actual professionals having to explain to their customers why all shots went south.

I just ran into this problem with a two month old 6D and two different 32 GB Lexar cards (600 and 200 MB/s). I CANNOT repeat the following using an 80 MB/s Sandisk card.

Just a quick fyi all: The problem with my sd card obviously originated from a defective *reader*, the card works fine. It's quite easy to forget this possibility, esp. as it's awkward to diagnose if you've only got one reader like a built-in slot in a laptop available.

i have a 5d3 all it does it lets you keep the bracketed shots as raw and it saves a jpg of your HDR or am i missing something.

It does?! Sorry, in this case I have to stand corrected. I tried the 5d3 several times including the hdr function in shops, but obviously I go this wrong. In theory, it's quite possible to merge several raw files into another raw file, Magic Lantern does it for their dual_iso feature.

On my 6d, I never use in-camera hdr as it's crippled to force-delete the source files (raw or jpeg).

fast moving?

You youngsters :-) ... and I wan't only talking of the slide speed, but the average hipness of the media folk people in the video.

doesn't dng have a good compression?

Sure, I'm all in favor of dng and even the lossy flavor. It's just that dng is often confused with raw files - so I just wanted to make sure this slide doesn't mean LR6 can assemble raw files into another raw dng like the 5d3 in-camera hdr feature can.

Looks like it makes a .DNG

I couldn't spot it, way too fast moving and too stylish people for me :-) but do note that "dng" doesn't necessarily mean "raw dng", but there's also the demosaiced flavor which is essentially a tiff.

Leonard Nimoy passed away today.

Oh my, all I need to know about life I learned from Star Trek! I feel kind of old now that my childhood idols start passing away. But it's no surprise, in his recent short appearance on the new Star Trek movies he already looked very much past his prime. Thanks for letting us know.

Btw: Let's not forget Nimoy redeemed the Star Trek universe from Shatner as a singer!
