i'd buy almost their entire DN line as soon as it became available for the M

My 5D IV does have a looser fit, I could not initially find the flap on my SL2, it was nicely done.

You can't really use the same optical design for IS and non-IS because you need the IS group... Can't just take a non-IS lens and add IS to one of the groups. Not in general anyway.

Feature come to DSLR too?

the 7D2 can do it by setting up the ISO to auto and
for me I customize the "SET" button as Exposure Compensation functionality.

So in Manual mode, I would set the aperture and shutter values and compensate the exposure after chimping the 1st test shot

For this lens, 400 mm / 67 mm front element size yields f/6.3. This is irrespective of the imaging circle.
An f/5.6 lens will have a front element of 400 mm / 5.6 = 72 mm minimum front element size.
This is why telephoto lenses typically have the larger imaging circle covering 35 mm. There's no advantage to only cover APSC.

Do you have a good source where I can go read on these relationships? There's a non-intuitive thing going on if that's the whole answer. Is there a focal length range where lenses are f-stop limited, and a shorter focal range where they're coverage circle limited?

I see a lot on f-number ratio, but I don't see a lot on the actual aperture position. Is it a theoretical aperture size at the front element?

Most of the articles I find are piece-meal, with few or no illustrations to clarify what's happening.

Nikon exits Brazil as digital camera cutbacks continue

Japanese company misread prospect of growth in South American country

TOKYO -- Nikon is restructuring its sales networks for digital cameras in overseas markets, taking steps including withdrawing from Brazil and shifting focus to factory equipment in Indonesia.

The Japanese manufacturer expects to sell only 4.8 million digital cameras in the year to March 2018, down roughly a quarter from the previous year.

Nikon set up a sales company in the Brazilian city of Sao Paulo back in 2011 when the local economy was booming and the digital camera market seemed poised to grow. The opposite proved true, with a particularly sharp contraction in cheaper, compact models -- the kind most threatened by smartphones. Competition among traditional camera makers intensified, making it a struggle to go on in Brazil, given the high tariffs, once consumer spending cooled.

Nikon is expected to continue to provide repair services for existing customers, but it has decided to close its online sales site, effectively ending its direct sales activity in Brazil for digital cameras.

Nikon is also changing tack in Indonesia. When the company set up a sales company there in 2013, the main focus was on digital cameras. But it ended direct sales of cameras this past spring and now just provides support for sales agents. The emphasis is now on is industrial equipment like x-ray inspection systems and contactless 3D measurement systems to meet growing demand in the auto sector.

Cameras and other precision optical equipment represent one of the few industries where Japanese names -- Nikon's peers include Canon and Olympus -- retain a technical edge on international rivals.

But faced with a shrinking market for digital cameras and slumping sales of its core business of semiconductor manufacturing equipment, Nikon is retrenching. It scrapped its original medium-term plan last November and announced a sweeping overhaul of its global development, production, and sales operations.

The company has already begun consolidating production of optical components and closing factories in China. It is working to reduce fixed costs in its foreign operations and allocate resources to priority areas.

I have been with Canon since the original F1N. I have begun to defect a little at a time over the last few years because I am tired of waiting for them to catch up with consumer desires and current technology. It is my opinion that when and if this new screen technology is ever implemented it will have absolutely nothing to do with what the consumer wants. Their line of lenses keep us tied to their line of cameras and they know it. Advances in their camera technology seems to embrace the idea that we will take whatever they decide to give us and we will like it.

It's not solely their lenses/lens-lineup. It's their ergonomics, how they render colors, printing systems, Service, etc. etc.

However, it would be nice if they would come out with a FF and APS-C (or H) that has in-body stabilisation, more DR, etc. etc. Pixel shift tech...

The bottom line is this though, for any of us, can we take the pictures we need/want to take for our business/clientele and/or hobbies? What system will best enable us to capture our vision - in the most effective, efficient, easiest/enjoyable, and repeatable fashion? And a similar question - that we each must answer when deciding on equipment/gear - is what is the bulk of my shooting entail? What are those needs in particular? Because the outlier situations, one can rent equipment for...

Final thoughts -- well, at this moment, even if I really wanted one, after seeing the preproduction unit, I sure wouldn't buy one, until it came out and I was sure the bugs were all ironed out. Boy, were there a lot, for a unit that they were demonstrating to the general public. Maybe I'm being unfair, but it feels like it's rushed to make Christmas.

Those 3 sigma modes don't have a clear explanation of what they actually do or what they should be used for. I think canon lens "is" functionality is the best.

Click to expand...

Quite correct. When you are a using a telephoto to pinpoint a small bird in a tree you need the viewfinder to focus on the bird and not wander off onto a branch and ruin the AF.

What got me going about this thread was testing a used 100-400mm II. It was brilliant optically on a tripod in live view and had good IS handheld for overall blurring by shake. But, there was blurring at the pixel level handheld at 1/200 - 1/400s. The pixel level blurring was not random, always in the same direction, and didn't happen with another copy of the lens. Either the IS couldn't react quick enough to fast twitching or it was vibrating.

It is a call for 120MP APS-H, that’s the most logical format to use, but the sensor format is not the main focus of the petition, resolution and pixel density are mentioned more than twice as much as APS-H.
This just happens to be the only format Canon has demonstrated for this type of product, and given that it does have many advantages it only benefits the idea to keep the APS-H sensor in the concept.
The next best thing to ask for would probably be a 50MP APS-C “Mini 5DS” but that’s underperforming compared to what the APS-H concept accomplishes.

Click to expand...

Well, your call for APS-H may be why you had such a poor response. Either that or people are not clamouring for 180MP FF sensor (or equivalent).
My guess is the latter.

Note to self: When raising a petition, make sure the title and main thrust of the petition text actually describes what I am after.

As always, great review Dustin!!
6DII was really disappointing imo

As one can see from examples in this thread, sometimes the iPhone panorama feature produces some good results. Sometimes I need to open them in Photoshop and straighten out distortions and crop to get the effect I wanted.

If I am somewhere without a camera (but of course with the phone, as always), I will try the phone's panorama and take a series of shots to stitch together as well. Then later, I can choose between them. There have been a few occasions where I did the phone pano even when I had a camera along, and then I'd use the camera to take the individual frames for the alternate version. Sometimes the iPhone version has less distortion than the stitched versions. I've not perceived any consistent pattern.

I've long ago completed my University courses. Sadly, my last living professor died last year. He was new at the time I went to school, so he was a assistant prof.

The second link works. I like the video. Paragliding is one the things I want to try in my life. Thanks for sharing!

It's finally a real problem only now that they have a solution. In the past, they just ignored it OR when pressed on the issue, say that super high resolution eliminates it (for the most part), which we all know is completely false.

Click to expand...

Can you explain how it is 'completely false'? Any examples? Compared low resolution sensors vs modern sensors?
It is like many things - when one problem is solved, the critics move the goalposts so they have something to complain about.

Ouch! My now retired 5D MkIII which was on it's third shutter showed very similar shading as the images you've posted when the shutter was at end of life. And on two of those occasions, the fault was intermittent.

If it is the shutter, that's very unusual for any 1-Series body. I'd be contacting and emailing these examples to your local CPS for an opinion.

Click to expand...

NEVER, NEVER, NEVER understood this claim. Especially as you say you're a professional. Speaking from the point of view of a business owner, why would you ever replace a shutter 3 times? In my studio I have multiple camera bodies (more than one 5D3), some with over 3ook actuations and this type of failure (3 dead shutters on one camera) would be a dump in the trash and another camera or different model. Just doesn't add up if you are a professional photographer...

Click to expand...

The first was under warranty. The other two were at around 130k actuations which really is pretty poor. But 5D shutters are relatively inexpensive, plus my studio is just 10 minutes drive from our local CPS. It's a very simple matter. The heavy lifting here is usually done with ridiculously durable 1-Series bodies, currently a high mileage 1DX, now backed up with a 5D MkIV and an admittedly rarely used 7D MkII.

It's a "feature", unfortunately. Touch AF is tied to shutter half-press AF in a sense so BBF only means BBF only. IMO it's annoying but you can work around it a bit by assigning "touch AF mode" to one of the C modes.

Chase Jarvis reviews the iPhone X in usual upbeat style. He knows cameras inside and out, and while he is a Nikon user first and foremost, he never bashes other brands.

He is also able and willing to hire a helicoptor to play with the phone camera as well as a pro film crew to film him. I don't know if they used a iPhone 10 to film him, my hearing is not good enough to understand everything.

Nice

I'm so glad I don't have a dog in this fight, I just can't stand the 50 on FF perspective and if I do shoot it it's on my 24-70mk2
It's just too frustrating waiting for what should be a foregone conclusion that Canon would have a great 50 and lower variants like they do a 35. SMH

I managed to set UniWB on my 5Ds R and would like to see how big the exposure difference between jpg clipping and raw clipping is.

Strangely, images that seem to clip a lot on the camera (only green) show a histogram which hardly clips (both raw & the internal jpg extracted using QuickJpegFromCR2). The contast, sharpening and saturation are all set to lowest value in the picture style 'neutral' in my cameras menu.

I use ACR to check the histrograms, could that be the source of the difference in histogram appearance between ACR and the back of the camera? Any suggestions how to check/measure it approximately?
