I would guess that parts of this would end up in the cinema side as part of the next generation of DPAF as well. Looks like some of this would apply anyway.

I'm having a hard time understanding how the camera could do Cinema video with focus stacking, and say 25 frames stacked for each frame of the video. It would mean 750 fps to get a 30 fps video, and a super computer.

All future DSLR's, except the bottom of the line units will be DPAF. that would have no impact on focus stacking that I could envision. The dual pixel output option of the 5D MK IV does not change focus enough to be useful for focus stacking from my experiments.

I might be thinking of something else...

Lee Filters and Filter Holder Protection

slclick said:
Well, actually I just saw that I use a Lowepro for my main pouch. https://store.lowepro.com/s-f-filter-pouch-100

It holds the holder and filters quite well. The Fotodiox was my previous smaller setup.

I had this pouch and used it for a while as it easily mounted to the outside of my lowepro protactic backpack and I didn't have to worry about making room for it inside the bag itself. All was fine for a while until one day trudgin through some brush and a twig or branch caught on it and all my filters dumped on to the ground! Damn thing does not shut securely and really needs to be closed with a zipper and not just a snap!

I tossed it in the garbage when I got home and replaced it with a Haida Pouch that zips shut.

I still sometimes use the Haida pouch when I go "filter shooting" but mostly I don't use many filters anymore except ND's occasionally and they are in my bag just in a tin all the time.

Patent: More Diffractive Optics Supertelephoto Formulas

Sorry for the hijack, just addressing the mirror issue..... With an "N" of 1. I used a Sony a6500 (mirror less APC) re: viewfinder. I turned off the screen and turned on the EVF to longest "on time" and then would occasionally do the 1/2 press to keep it turned o i.e. no start up lag, etc. (30 mins if memory serves me)

Shot over 6 hours on 1 little battery, chimping on the screen certainly kills battery.
-0- black out at 11 fps (tiny stutter but was able to keep all the birds in center frame all the time)
When I shot my 1dx EVERYONE within 50 meters knew I fired off a burst. When I shot the Sony NO ONE knew, even the guy 1 meter away. Virtually silent.

SOOOOOO. if you are into wildlife, the silence is golden. (though my otter shots came from my 1dx and his curiosity which was different than I expected)

I have both a 5d3 and a 1dx. 16-35 f4, 24 art, 50 art, 70-200 II, 150 -600 tammy, 90 T/S. All EF mounts. Rented Sony a6500, 5d4, 5dsR. (re-entered photo w/ a t3i which daughter now shoots occasionally) All told, quick file counts (don't delete anything, space is cheap) have the total frames at just below 250k

Skipping the 5d4/1dx2 generation. Looking forward to the 5dsR II (if it comes outs and wouldn't be so cool if it was mirror less).

All of this is to express - go rent one. Experience it. Yea the adapter kluge affected autofocus (cool Sony has peaking) but but but but but it is clear with a tech advancing (most places) as it is EVF will outperform the mirror - can't turn up the gain on a mirror like an EVF.

My experience leads me to pine for a Canon "pro" level mirror less. Wouldn't it be cool if they advance the SOA of the EVF and stick on the 5dSr replacement AND the 1Dx3.

...removal of cross-threaded uv filter stuck on Canon EF 17-40 f4 lens

I am going through many of my EF lenses to see how well they 'work' when connected to an M6 via an EF-EFM adapter.

A lens I only use occasionally (because the 'killer app' of the M-series--the 11-22 EF-M lens, yields great wide-angle images with the M) is the Canon EF 17-40 f4 lens; and before testing it with the M6 I attempted to remove the uv filter which has resided on the lens for at least a couple of years.

Sadly, the filter could not be removed; using Mr. Google's suggestions and trying jar top removal tools, rubber bands and leather shoelace,s and even a bit of cold weather did not enable the removal of the filter from the lens.

An individual at the bottom of this link (https://www.photo.net/discuss/threads/cross-threaded-lens-filter.438251/) described how he removed a filter that had been cross-threaded to a lens. His way worked for me, too...after I figured out that was my problem.

I took a look at the 17-40, at sure enough, the 77mm filter was on a bit crooked. With the aid of a kind of scalpel-like tool that has come in handy for taking (prying) apart watches, phones, toys and laptops, I was able to wedge the scalpel into the tiny crack between the filter and the lens...and then carefully slide it toward the other side of the lens, where there was virtually no space at all. Just a bit of wiggling...and a tiny snap (!) was heard...and easily removal of the uv filter was accomplished.

...this post is hopefully an unneeded tip for CR readers--you've helped me plenty.

Canon EF 70-200mm f/4L IS II Coming Very Soon

I think a f4-Lens is ok for some people, let's say hobbyists, but most want the 70-200, simply to get a better depth of field and especially to use teleconverters like 1.4x or 2.0x.

Let's not say "hobbyists", because the lens is used by landscape photographers, including one I know of who does actually earn his living from landscape photography. As has already been said, it's a lighter lens to carry than an f/2.8. Landscape photographers usually shoot stopped down, many or most of them all the time.

I'm with you as there are many folks whom act as if all lenses should be fast, never used at narrower apertures and all that jazz. It's not all portraits and shallow DoF guys.

It's not all about hiking for miles to shoot landscapes from tripods at narrow apertures, either. For many of us, it is about some combination of both.

The thing is, though, you can always stop down an f/2.8 lens to f/4, f/8, or f/11. You can't open up an f/4 lens to f/2.8 when you want/need to. That makes the f/2.8 lens more versatile.

The price you pay for that versatility is in size, weight, and cost.

It's up to each shooter to decide if the extra functionality of an f/2.8 lens versus an f/4 lens is worth those things.

It's up to each shooter to decide if adding a 70-200/4 for use when size/weight may be more important than maximum aperture to a kit that already contains a 70-200/2.8 is worth the cost.

Yes, a very obvious counterpoint to my post. I am aware you can do more with more, it's just some can do very wonderful things with less. Although contrary to the ever popular GAS, 'Less is More' is also a very common although outdated photography axiom. Furthermore, I would never suggest that an f/4 version for an f/2.8 owner would be have a place in very many shooters kits, only a select few.


Why can't we agree to agree? I had the f/4L IS and then picked up the f/2.8L IS ll with the intention of selling the f/4. I didn't and I'm not going to. The f/4 gets brought along 75% of the time, but when you need 2.8, you need 2.8. I have the 100-200mm focal length very well covered...

The TIPA and EISA Award Winners Have Been Announced

tallrob said:
I heard the same tripe from my fellow pro shooters back when I bought my 6D as an upgrade to my 5Dii. They were all happy to pay $1000 more, and laughed at my cheaper, lighter, wifi enabled, better IQ... HEY! Once they found out the absence of the moire filter resulted in better IQ, they stopped laughing. And they were jealous of the wifi as they fumbled over their cables for tethering. Try getting a remote shot on a boom 15 feet in the air without a trigger or usb cable attached. No chance. And I used the money I saved to get my first Sigma Art lens. Sweet little piece of glass.

"Professionals" love to carry around their white L lenses and latest body upgrades so people know they're "pro". I'm perfectly confident my work shows my level of professionalism, not my gear. I'm actually glad the 6Dii wasn't such an improvement over the 6D, because I almost got sucked into the mythical DR craze, even though I've never had a complaint with the 6D's shadow detail on a sunny day, where the scene matches exactly what my eye saw. (HDR is overrated, ladies and gents). So I saved another $2000 not upgrading, and I'm still perfectly happy with my 6D.

That said, I'm certain all the hating on the 6Dii is just as much b.s. as it was five years ago.

I don't keep up with these things that much, but hasn't the original 6D suddenly become wonderful in the eyes of the haters now that they have the 6D2 to hate?

BTW, I noticed the other day when looking at metadata that the autoexposure had finally, after seven months, shot a picture on my 6D2 at ISO 100. I didn't see anything wrong with it, though.

Using off camera Canon speedlights with Sony camera

daniela said:
Hi Guys!

My daughter ordered an Sony A7 III these days. One thing, she is interested in, is making portraits in the nature with three or four speedlightes. Normally she used my Canon equipment for it, but she wanted an Sony.

Do you know, if it is possible to use my Canon 600 RT flash and three Yongnuo clones with the A7?
Not mounted on the A7, but radio/... triggered as sattelites when she mounts an Sony/... flash unit or an radio trigger on the A7 body?
Is there an way to use my flashes, or has she to buy new one?

Thanks for your help
Daniela

What I learned today is that a YN-E3-RT on firmware 1.25 on Legacy Mode, on a Nikon D4, will trigger Canon 600EX-RTs on manual mode. It won't trigger Yongnuo YN600s, oddly enough.

I learned about Sony's new hotshoe as well - it sounds like the Yongnuo transmitter should fit directly.

Good luck!

Canon 5DM3 refurbished

docsmith said:
Did you run the shuttercount through something like www.eoscount.com? Or is the # count you mention just the picture number.

The refurbs I have bought have all started at 0000, but when running them through some sort of software, you see that they have had actuations.


When I first turned on the camera, it stated "O" shutter actuation on the screen. In the past, when I've bought refurbished cameras, when turned on they had XX number shutter actuation - so it seems to me, when it comes from Canon, it shows the number of times the shutter has been triggered. It's the only time that particular screen come up - once it's shut off, then it never comes up again. And, I don't think there is a place on a camera that documents it ... it takes a program to count it after that first time. I'm not very tech-trained, so this kind if info often eludes me ...

I'm not sure the "picture count" would matter, because when you change cards, the count changes as well, at least it appears that way -- and when it DPP, for the initial download, it sorts into "which camera" shot it too in the folders ...

I have never seen the camera, new or refurbished, display the shuttercount initially upon turning it on. But, I bought my 5DIII new, so maybe it is something specific to it.

I am a big fan of refurbished products from Canon and they make up a good portion of my kit. But, if you really want to confirm how many accuations have been made on your camera, I would pay ~$3 and have eoscount analyze a picture. Do not be surprised if the number is greater than you think. Or, you may have received a new camera and they are clearing out inventory.

Either way, I am sure you have a great camera.

It feels and acts like a new camera, if that makes sense ... and a few test shots look great. I'm running it thru some field test today and tomorrow. I've bought refurbished in the past, as well as new, and can't tell the difference just looking at it. I agree, Canon refurbished is excellent program.

MOF- I bought a 5DM3 new, and don't recall that window popping open, but bought a 7D and a 60D refurbished and it did give that count first time I turned it on ... 7D had eleven, and 60D had four ... as I recall it.

I tried to buy the 24-70 f4 IS refurbished at the same time, but Canon screwed up the order - twice ... then, when I saw the price after tax and shipping, and with NO case or hood, I went to B&H and for about $90 more, got a brand new one in two days. Happy camper here !! :)

Intervalometer with time-of-day control?

lion rock said:
This is what I have and used at 10 minutes interval for two days. Transmitter and receiver use 2 AAA batteries each. Can't say if the batteries were drained, but certainly can operate even longer. Maybe lithium cells may provide longer use per set.
BTW., the transmitter can be connected directly to the camera through a cable, bypassing the wireless function (thus the receiver). Without the transmitter activated, it might run even longer period.
You may have to order with the appropriate cable for Canon.
B&H should carry this.

(I am not involved either company, just a user.)
-r

I need to take multi-day picture sets and can't disturb the animals I'm photographing, so I need an intervalometer that can allow me to set what time of day it starts and stops. I have many of these devices, and none appear to give me that level of control while not being with in bluetooth range with a controller. This is about a mile in the woods at a site without power.

The cameras are powered with car batteries, and I have all that set pretty well. I just need the intervalometer. Would rather not have to make one myself by coding some arduino thing where I'd inevitably create many bugs and have to suffer through my own poor user interface.

Anyone know of anything out there? Thanks!

did you mean to give a link?

BenQ SW271 4K Photo Editing Monitor Review | Dustin

Jack Douglas said:
I wouldn't have it any other way as well. They don't have to reside in a single plane and the secondary one can be a cheaper model that's fine for most activities.

My little 20' BenQ has performed flawlessly for about 12 years and is sharper than my 24" newer Samsung - that's why I have started to consider a pro BenQ model. Hope they continue to manufacture dependable products. ;)

Jack

I used dual monitors for almost 20 years. From 2006 through most of 2014 I had my old LaCie CRT hooked up along with a 23" LCD. I used the latter for my main screen, and kept palettes and such on the CRT where color shifts and such didn't matter. Nor did difference in resolutions. I arranged them in software so that when I moved the mouse pointer between them, there was minimal vertical shift.

In late 2014 I got a 5K iMac, and figured I'd get an adaptor to add the 23" screen to it. But I have left the old Mac Pro hooked up to it, and still crank it up for an occasional project, mostly audio. Using both computers at the same time is a little confusing in that I will type something on the wrong keyboard or move the wrong mouse, but otherwise is easier than migrating everything to one computer just for doing something every few months. I've got used to having a blank screen to my right the rest of the time. Once I got my desk layouts to suit me in PS, Dreamweaver, and Illustrator, I find the 27" monitor is almost always plenty of screen real estate for what I do, and I can always preview video full screen at 5K. And even with the CRT and 23" LCD, it wasn't that handy to move the mouse pointer from one extreme edge to the other. That's likely a lot of why I like sticking with one fair-sized monitor. But back in Olden Times, dual monitors were really useful and handy.

Tony Northrup Predicts The Upcoming Full Frame Mirrorless Offerings From Both Canon and Nikon

I'm still hoping to rent a TS lens for a week as a kind of "staycation" of taking pictures most of the week, and playing with the characteristics of the lens. I'm hoping to decide on a week before hot weather and I get busy with a college reunion and other stuff going on in June, so maybe a week in May or in the fall if I can't work that out.

I'm thinking in terms of the 24mm TS, but could be swayed toward the 17. The former might be easier to tame for someone completely inexperienced with TS like me. I have read the articles from links people on this board have shared with me, and will review before the rental. Thanks to those who answered my general questions a while back.

And there's nothing to preclude my renting a different one at a later date. Just coming up with a week that I would have enough time to make it worthwhile is more of a factor than the $125 or so. (That's cheaper than one hotel night on a non-stay-cation.) I'm retired, but rarely run out of things to do. I live in a college town, so things slow down after the students get busy with papers and exams in May.

Patent: Canon Continues Stacked BSI Sensor Development

Isn't the stacked BSI sensor technology what Nikon is using in their awesome D850? I'm hoping that the reason we're not seeing a 5DSR II this year is that they're trying to get their sh*t together on a BSI sensor to compete in this market of which they're behind.

If you're impressed with the d850 sensor, you're impressed with Sony. Nikon has basically become the DSLR arm of Sony. When Nikon releases a FF-mirrorless, it will act as a "satellite team" for Sony, meaning they will not get the latest or best sensors to keep them in their place. So it's really a two-horse sensor race between Sony and Canon, and although I agree that Canon is behind, it is not that far back as DPR has one believe (in fact, Canon sensors have advantages over Sony, including dual-pixel and color science).

Nikon doesn’t use a Sony sensor in D850.

Officially, they don't. Unofficially: https://www.sonyrumors.co/dpreview-nikon-d850-sensor-is-from-sony

Even if you don't believe that reference, for Nikon to pull out their first BSI FF sensor from scratch and then underprice the 5d4, just makes one wonder. The MP count is also close to the a7r's, another interesting coincidence. Oh, and it has the same green-cast issue as Sony sensors: https://www.dpreview.com/news/7999477966/nikon-d850-firmware-1-01-fixes-long-exposure-green-cast-and-other-minor-bugs

I don’t believe that reference, and I certainly don’t believe Nikon made them. I also don’t believe Sony has production lines for two full frame BSI. Option 3: there are plenty of CMOS fabs out there who are hungry for customers. It may as some rumors suggest be TPSCo.

Indeed it may be fabbed at the sony-owned Toshiba plant. As far as I know no one has torn one apart far enough to know definatively.

Either way, it’s almost certainly not an off the shelf Sony design.

Introducing the Canon EF 100-400 f/4.5-5.6L IS II

stevelee said:
I received my 100-400 II yesterday and had a few moments free to try it out to make sure it got here OK. I shot handheld with all settings on auto. I shot birds at the feeders next door and the remaining blooms on the dogwoods in the woods behind the house. I was standing on my deck, which is about 20 feet off the ground at the edge. I used image stabilization mode 1 and all camera settings on automatic, shooting RAW on a 6D2.

It is my first L series lens. It is also the biggest and heaviest and most expensive lens I own. From these quick shots, I've decided it is definitely worth the price, and I'm glad I chose this particular lens for my current purchase. The IS does an amazing job.

Here are a few 100% crops for you pixel peepers. The software of this board shows them enlarged a bit, so they appear noisier than in reality. Birds were shot at f/5.6 1/320 sec. I did the dogwoods in AV mode at f/16, so the camera used 1/400 and raised the ISO a bit.

Congratulations on the lens! The "L" virus grows and you'll find it spreading, especially if you are shooting full frame. That is my experience. Full frame and "L" together makes the angels sing.

Interview with Venus Optic's Laowa lens designer

At the recent UK photography show I had a chat with the people from Venus Optics about their Laowa lenses - and followed up with their chief lens designer.

I've tested all EF mount Laowa lenses over the last few years and have written up a short interview with some of their comments at:

http://www.northlight-images.co.uk/interview-with-venus-lens/

Perhaps not as detailed an interview as I might have liked, but translation does make it a bit tricky

It seems that they are going to be showing some new cine lenses too, in the near future
