Canon General / Re: Opinion: The myth of the upgrade path
« on: January 10, 2015, 10:22:58 AM »
Rather, the 'myth' to which he refers is that upgrading to full frame is a path.  He contends that it is instead a leap.
Yep, and I'd agree. As someone with a 60D who wants a 6D, part of what holds me off from doing that is that any upgrade requires 2x the price of the actual camera, when you get lenses involved.

My 17-70 and 55-250 obviously become useless, and the cheap options for replacing them are all $500+. To get the matching focal range of the 55-250, most of the lenses are closer to $1000.

And I do mostly landscape work, so I can go the manual/legacy lens route. Still doesnt make it an easy "path"

EOS-M / Re: Why do I keep my Eos M?
« on: January 09, 2015, 08:32:39 PM »
Sounds like you might be a candidate to sell the M and and get an SL1. Its actually a very similar in height and width, though obviously its deeper (with the mirror and all). Combo that with the ef-s 24mm and you have a set-up that isnt that much larger than the M and 22mm (neither is truly pocketable, and both are reasonably small and light). And one delivers usable AF, a viewfinder, and compatibility with all the lenses you already own.

Animal Kingdom / Re: NatGeo 2014 Photo Contest Winners...
« on: January 07, 2015, 11:27:11 PM »
The light in photos #1, #3, and #4 are pretty amazing; and even as common as that wildebeest shot is in this contest, its still really impressive. And I love the negative space and colors in #16.

Which makes it weird to see photos #11 and #13. I guess I can see the playful irony in #11, but, it isnt capturing anything particularly interesting, and the composition isnt that strong. And #13...aside from being an interesting moment...has nothing going for it that I can see. The composition and light are boring, and I can't tell if its the lens or the aperture used, or maybe the focus is a little off, but the depth of field and sharpness isnt working. In comparison to #9, its night and day.

Reviews / Re: www.photozone.de reviewed EF-S 24/2.8 STM
« on: December 26, 2014, 07:16:38 PM »
Haven't people been whinging out Canon not making dedicated prime lenses for APS-c ? Now one has been produced they are claiming it should have been FF ?  ::)

If I was a crop shooter I'd be very pleased with this offering. 38 -40 mm FF equivalent is a great all purpose focal length.
Im ecstatic. Means I can ditch my 17-50 zoom and just stick with 11-16/24/55-20 when I want a light but fully functional travel kit. I wont really be missing 24-55 at f/2.8 or f/4, as those can easily be covered by moving my feet.

And for when im on long trips, just taking the 24 means I can have a really light combo with my 60D

Of all the answers he gave, I'm not sure the lack of innovation angle is the one I'd run with. It was one of his shortest answers to a question that came pretty late in the interview. His answers about electronic shutters and light field cameras were far more interesting and telling. Also, his answer about the continued viability of APS-C

Third Party Manufacturers / Re: FYI: D750 light leak issues
« on: December 24, 2014, 12:24:01 AM »
Seems that those cameras where the sensor is set deeper do not have these reflections which again points at a problem with quality control, not necessarily design.
Weird that Nikon would allow so many of their recent cameras to have such a similar set of problems over a multi-year period that seem to be QC issues. We basically only have the D610 and D810 for that reason, and the D760 seems next. That's a trend that makes it hard to pre-order a Nikon camera.

Looks like I'll be able to get a D750 for cheap.
Which, leads to an interesting aside. On one hand, it has to hurt Nikon's bottom-line to refund/repair so many warrantied cameras, and it also has to hurt them to issue a D610/D810 and see that market die to used sales of the D600/D800 (that they repair for free). But, in an odd way, it makes their entry level really cheap (D600 is <$1000 used), which could lead to them gaining customers.

Post Processing / Re: DNG vs. original RAW in the long term
« on: December 22, 2014, 12:04:46 PM »
In another thread it was recommended to always keep the original RAW files, because RAW converters improve over time, and converting old RAW files with new converters would potentially give significantly better results than what was possible a few years ago
This is definitely true, I've notice an improvement in ACR over time, and so I go back and re-convert my favorite photos every year or so to see if they turn out better. Highlight recovery and denoising have gotten a LOT better in the last 3-4 years.

Personally, I'm not worried about it, there are SO MANY images out there using Canon's RAW format I don't see any software "dropping" it any time soon.
And even if the major programs did drop it, two things would happen

1: It would be very publicly announced, probably with about 5000 posts on this forum and every other forum. And someone will make the tool that turns all your RAW format photos into whatever the new format is en masse.

2: Someone would create a legacy converter that works on every platform. I mean, Magic Lantern alone creates converters for the proprietary formats that create for RAW video and HDR video and Dual ISO shots...they'd easily be able to create a CR2 converter for everyone if they made that format obsolete.

So, my conclusion is to archive them in their native format. Because then you know they are lossless. And in the future, should that change, converting them will not be any more difficult than doing it now.

Third Party Manufacturers / Re: 40-50mm for a7r
« on: December 18, 2014, 10:51:46 AM »
since I will only be using it in manual focus with the appropriate adapter so any mount will be ok just want something that's not to expensive but reasonably sharp especially wide open, any suggestions?
Canon FD 50mm is pretty solid, but the SSC and FDn versions, I use it for my video work.

Dont have experience with the Nikon options, but I imagine the AI versions of their f/1.4 and f/1.2 are very good as well

Third Party Manufacturers / Tamron 15-30 f/2.8 VC
« on: December 18, 2014, 10:28:07 AM »
The leaked price is apparently $1499, which makes it a pretty interesting option if they've kept the lens sharp at 15mm f/2.8.

PowerShot Cameras / Re: Canon to Target The GH4 With New DSLR Type? [CR2]
« on: December 15, 2014, 09:31:54 AM »
Well, the 1" sensor also means they are also competing with the digital bolex, the BMCC and BMPCC, and a handful of other strong, cheap options. Find it hard to believe they'll drop ProRes or RAW support into their camera like the other manufacturers have...so, it'll be interesting to see what Canon does to not make the product dead on arrival.

I think others have given you better suggestions than I could, but I do use my Clik Elite pack for overnight trips. Rather than downsize my camera gear (which is a great suggestion), I downsized my camping gear. Just a hammock and a sleeping bag that packs small. A bivy/bag combo would also work. Basically, I make it that my food, clothing and  sleeping gear easily fit into like a 25L pouch in the top of my pack.

But, for a multi-month trip, I'd probably take the opposite approach and downsize my gear over roughing it with sleeping setup

EOS Bodies / Re: 4K Fixed Lens Camcorder Coming? [CR2]
« on: December 05, 2014, 09:18:39 PM »
Of course we're all speculating to some degree, but from reading the description given here, it sounds like it will be a relatively small sensor camera (1" or less) because it will have a fixed lens and will also possibly be announced at CES so more of a prosumer/consumer camera.  I took the statement "it will have similar ergonomics to the EOS C100" as meaning the body will look similar to the C100 along with a similar button layout and a top handle with XLRs.  I think it would be awesome if it has a sensor that's as large as the C100's and hopefully it will, but to me it sounds like it will have a similar shape to the C100 but not necessarily similar sensor.
To me the biggest giveaway is the name. XC10 sounds like its basically the in-between line of the XA series (XA10, 15, etc) and the C-line. So, maybe it'll have a slightly larger sensor (maybe 1" to the XA's 1/2.84") but a lesser zoom range. Which actually would make for a great event/interview camera for my work.

I love the XA line, so, anything they can do to improve that is a win in my book

Can someone please explain simple /me how it has more dr at higher iso?
The simple explanation is basically the same explanation for how actual film had ISOs (100, 400, 800, etc). Each was designed to have maximum performance at that base ISO. Digitally, sensors have a sort of "native" ISO where they perform best. Many stills cameras work best in the 100-200ISO range, while many cameras designed for video tend to be in the 400-2000 range as "native".

Red talks a bit about it midway into this post: http://www.red.com/learn/red-101/iso-speed-revisited

Ok, but sarcasm aside - from shooting with ML's dual_iso I have a vague idea how much dynamic range daylight high-contrast shots have. I'd say with 15-16 stops you should be really covered for most natural scenes, 14 is fine for most purposes unless the sun is in the frame. So what's 21ev for?
Flexibility. I can always add contrast and crush the ends of my levels to turn it back into 15-16 stops, but its much harder to turn 15 stops into 21. Could be especially useful if, for shutter speed reasons, you need to under or over-expose signficantly. I dont mind clipping highlights if I wasnt gonna use the top 3 stops anyway, if that's what I need to shoot at the right shutter angle.

It's mostly a question of "why not?". Do I really need to be able to shoot cleanly at ISO6400? No, but, I might be able to save a lot of money on my production using an A7s cause I need less light.

edit: Other thing that occurred to me...it could, combo'd with the Movi system, etc...completely change moving from indoor to outdoor for filming. If leaving a bright outdoor scene and moving indoors I change 7EV, with a 21 stop sensor, I might not even have to pull exposure as I change between those scenes. I can just adjust my color grade in post.

Of course, as Red Dragon showed, "21 stops" is never actually 21 stops...it'll be 17 or 18, which will be about perfect.
