I have a question to those that own a 5ds or 5dsr. I took the early plunge and purchased a 5dsr and have a question to other lucky-? owners.

I recently took it on a photography trip around Colorado. During that time I attempted to utilize the dual card slots with simultaneous writing. In the past with my 7DII I always did a sequential setup that always worked well. However, I found that during this trip the cards would lock up and sometimes become unreadable. The first time it happened with a brand new SanDisk CF card and SD pair. The camera wouldn’t do anything until I ejected the CF Card, even though the camera initially reported Card 2 as having the problem.

This particular behavior didn’t occur again and I thought I might have just received a lemon of a CF card. However, when I got back to the hotel to download my images I found several cards had reading issues and many images were not able to be downloaded.

About 3 days into my trip I decided to turn to SD cards only and go with that. After that everything was fine.

Anyone having a similar experience?

Thank you.

Going to the Portland Hillsborough airshow Friday night. I am wondering what equipment I should bring from wide angle to telephoto lenses. I'm thinking one of each for weight concerns. The gates open at 6:00Pm and the show closes with fireworks at 10:00, so there may not be a lot of bright light.

I was thinking of a 300 f2.8ii with both 1.4 and 2x extenders, and a 24-70L on a 1DX with a backup SL1 and a gitzo tripod either a ball head or wimberly that mostly for the fireworks. There will be some walking but with seating at what is billed as an "umbrella table". The show web is here http://www.oregonairshow.com . I have access to a fairly wide variety of lenses but no sherpas. Here's the potential tools let me know what really works best...
taking now:
300L with extenders
24-70L
40 Pancake
tripod with ball (fireworks shots)

Could substitute:
70-200L
16-35L
8-15L Might be nice for walking around and interior shots if they are allowed.
14mm manual focus rokinon

I'm hoping there will be some walking around, I've never been to one of these shows before so don't know exactly what to expect.

Any quick technique ideas would be nice as well.

The Blue angels perform the next day, but I needed to travel so I'll miss the daylight show.

I've been playing around with the new 5D sr to see how it behaves in the macro area. I shot some small orchid flowers, total height 2 mm each, with MPE 65 mm at 1:1, 2:1, 3:1, 4:1, 5:1 and with TC 1.4xIII at 7:1. Each set at f/2.8 and f/4: all open for maximum resolution (here meant as the traditional separating two points in object), and 1 stop down for possible aberration correction and overall improved IQ. Between 60 and 175 frames were shot per set-up. Flashed manually with MT-24Ex at around 1/64-1/32 power, so very short exposure times. Flash heads mounted off lens to ensure consistent illumination angles. Stacking done on Cogynsis Stackshot with steps down to 19 µm. Stacking steps calculated as 70% of DoF with c = 0.03 mm in 8 x 10" print.

Processing on 6 core MacPro soup can with 32 GB RAM. Mac OS Yosemite does not reliably display thumbnails of CR2 file icons in finder. No idea why. RAW files were run through DxO (latest download). In previous DxO you could double click one image in directory, and all images in that directory would load, but this leads to many errors and hang-ups with 5Ds files and latest DxO version. Drag-drop images into the DxO interface is 100% reliable. It takes time to process >100 files, but can be done on MacPro. Activity monitor had all processors going full throttle for several minutes, with quite a bit of heat coming out of the vent. I would not advise doing that on a laptop.

In previous tests with 5D2 files, RAW file processing was quicker in DxO than in PS CS5.5 extended with batch processing.

Stacking in Zerene with 300 MB 16 bit .tif files was flawless. For me the P-max algorithm works best.

With the huge file sizes and small pixels, the question arises at what magnification is nothing gained anymore in terms of better information? This point is reached at 4:1, where f/2.8 becomes effective f-stop f/14. This is a bit higher than what diffraction limited calculations arrive at (f/6.7–11, in most discussions). f/4 resulted in slightly softer images.
Comparing 5D2 images of same plant to the 5D sr, 5D2 still gains information at 5:1 (did not try 7:1), but still on fewer pixels. With 5D sr you can take a larger field of view at 4:1, print larger, and crop heavier, and get same information, mostly as expected.

Attached is a 4:1 f/2.8 image, 111 image stack: full image height down sampled to 1000 pixels, cropped some of the black side areas out. Again, flowers are 2 mm high, the bubbles are individual cells, about 20–40 µm in diameter, resolution limit seems to be at around 10 µm, which is about right for anything short of epi objective lenses on compound microscope. On dedicated stereomicroscope you can get down to around 4–6 µm (1.22 lamda/NA).

Enjoy!

Just looking at the sales price trend of the 5D3, 7D2 and 6D, I have to wonder if the 6D or 7D2 should be considered relative disappointments to the 5D3.

For a host of reasons, Canon was pretty ruthless with the price of the 5D3 -- holding a very hard line with authorized resellers for nearly 3 years. But the 6D has seen a steady price drop since it's release, and the 7D2 just took a 15-20% price cut within it's first year.

Should we interpret that as Canon was too unreasonable with their initial pricing, or is there a competitive product that is outperforming it (sales-wise)? Or perhaps the market as a whole is down and Canon is chasing it by discounting those products?

Just curious.

Bryan at The-Digital-Picture has completed his review of the inexpensive and overachieving EF 50mm f/1.8 STM.</p>
<p>From The-Digital-Picture:</p>
<blockquote><p>It is easy to love a lens with perfect optical quality, best-available AF and first-class build quality. Start dropping any of those attributes and size, weight and price concessions are expected with the amount of the price concession being the all-important factor for many. In this case, the price concession is very substantial, easily making the 50 STM Canon’s lowest priced lens. This ultra-low price, combined with an extremely light weight (only Canon’s pancake lenses and the 50mm f/1.8 II are lighter), very small size (only Canon’s pancake lenses are shorter) and impressive stopped down image sharpness, immediately (and unsurprisingly) launched the Canon EF 50mm f/1.8 STM Lens to the pinnacle of Canon’s best seller list. <a href="http://www.the-digital-picture.com/Reviews/Canon-EF-50mm-f-1.8-STM-Lens.aspx" target="_blank">Read the full review</a></p></blockquote>

Hi All,
Used Canon 550ex is selling ~$125 on ebay which is roughly same for Yongnuo YN600EX-RT?

Can you please suggest which one should be better?

As 550ex is used the bulb life is reduced I think.

I use 600D with popup flash diffuser. Which is
1: Harsh for close range [better than no diffuser]
2: Very insufficient on outdoor
3: And 18-135 with hood casts shadow on ground at wider focal lengths.

My budget is ~$125.

FYI on LensTip's review of the 5- f/1.8, which dropped yesterday:
http://www.lenstip.com/index.php?test=obiektywu&test_ob=444

For the sharpness nuts, here you go:

Old: http://www.lenstip.com/424.4-Lens_review-Canon_EF_50_mm_f_1.8_II_Image_resolution.html

New: http://www.lenstip.com/444.4-Lens_review-Canon_EF_50_mm_f_1.8_STM_Image_resolution.html

I toyed with making an animated gif of the two charts for a quick reference, but just toggling back and forth between two browser tabs should do you.

Looks like center sharpness is unchanged through the aperture range, but corner sharpness gets a nice bump through most of the business end (f/1.8 - f/8) of this lens. Nice work, Canon.

A report over at Northlight mentions testing of the EOS 5D Mark IV.</p>
<blockquote><p>There is still a mix between 18 and 24MP. 24MP is the likely final outcome, with the lower MP sensor testing AF speed and buffer management issues (less than 8FPS is the likely shooting speed).</p></blockquote>
<p>We’ve heard recently that the camera is coming in 2016, with shipping of the C300 Mark II and EOS-1D X Mark II to happen before the EOS 5D Mark IV. There’s a lot of R&D dollars going into the 5D4 project, with the hopes of launching a product that is perceived to be a big jump in features and performance over the more-than-capable EOS 5D Mark III.</p>

"A report (thanks) of 5D4 testing, where there is still a mix between 18 and 24MP. 24MP is the likely final outcome, with the lower MP sensor testing AF speed and buffer management issues (less than 8FPS is the likely shooting speed)"
Keith's point to that: If this is so, then it suggest that the 5D4 launch is still some way off?

There hasn’t been a lot of chatter about the EOS-1D X Mark II, which tells us the camera probably isn’t what’s coming on the <a href="http://www.canonrumors.com/2015/07/canon-announcements-coming-august-14-2015/">rumored DSLR announcement on August 14, 2015</a>. If it is, I definitely expect to see some teasers from Canon in the coming week or so. For now, we’re betting on some kind of an SL1 replacement if the announcement date rumor is true.</p>
<p>We’re told that the all new autofocus system in the EOS-1D X Mark II will have considerably more AF points than the 61 in the current camera. Most of the points will be crosstype, though the exact AF point number wasn’t known. The viewfinder will also feature some new technology to “handle all the additional points”. It’s also likely we’ll see the return of the solid red AF point when in AI Servo mode.</p>
<p>We’re also told that there are test cameras with OLED displays, but whether or not that makes it to a production camera is unknown. We also don’t know if the OLED test screens are for the top display, or main LCD, or both.</p>
<p>Ergonomics aren’t going to change all that much, but there will be “further button customization options”.</p>

Move over, medium-format, there's a new back comin' to town!
Packin' 12 million big, fat, 75-micron pixels on a 9 x 11 INCH sensor and a base ISO of 2100.

I wasn't super-thrilled with my P1 test experience, altho very good gear, better bang/buck from the pentax kit, IMO. I've been thinking about REAL large format digital for a while, apparently someone else has been thinking about it hard enough to make it happen.

MF is not all that much bigger than typical 35mm format, kinda like comparing FF vs APSC crop body. There's a noticeable difference sometimes, but it's not huge.

These large sensor backs from http://largesense.com/ are in a completely different league.
The camera's still in the prototype stage, nearing production from what I've learned and a 5x5 inch version is also planned in various versions.

http://largesense.com/products/4x5-large-format-digital-back-ls55/

here's a direct link to the info page for the 9x11:

http://largesense.com/products/8x10-large-format-digital-back-ls911/

I won't disclose other technical info at this time as parameters are subject to change. Suffice it to say, this could be an extremely capable and impressive camera in many respects, providing a type of image you just can't do with present digital imaging systems.
It looks like it's going to be a lot of fun to work with.

Sabaki · Jul 11, 2015

Hi everyone

I'm definitely picking up a full frame body soon but I am struggling to work out which wide angle zoom to buy.

I was having a hard look at the 11-24mm but felt that the price, the f/4.0 aperture and my ability to use the 11mm range effectively puts it out of the running for me.

I am very interested in the 16-35mm mkii though as I am very impressed with the sharpness across the frame, as well as the punchy contrast.

I will be using this 99.9% of the time for landscapes and star trails on tripod but I do have a concern about the largest aperture of f/4.0. All my experience with star trails says 'go to f/2.8' and I'm unsure if f/4.0 will be unsuitable for star trails.

Canon Rumors made mention of a possible 16-35mm f/2.8 L mkiii and if this lens offers the same IQ as the f/4.0, I'll jump on it in a flash.

As you guys can see, I'm aiming for a lens that doesn't exist, worried about the aperture of the f/4.0 version and dismissive of the 11-24. Anybody willing to offer me some good advise or experiences of their own that may help me make up my mind please?

T.I.A.

I have been using the 24-105L lens for many years of pro photography. I decided to take the leap and buy a 24-70L mk2 recently so I could shoot more often at f2.8 for better bokeh. The lens I have is just not that sharp compared to my old one...also exhibits a lot more flare. Once in a while I get a really sharp image, but most often, just so-so. I also use the 70-200f4 L, which is just great and the the 35 f2 is and the 85 1.8...all on 6d bodies.

As always, a fascinating read from Uncle Rog and his pal Olaf:
http://www.lensrentals.com/blog/2015/07/variation-measurement-for-50mm-slr-lenses

A few fascinating bits:

The new Canon 50mm f/1.8 STM (with its old optical formula) is off the charts for high consistency / low copy-to-copy variation:

"The Canon 50mm f/1.8 STM was amazingly consistent, and I'm not sure why. It's a simple design, but so are several of the other 50mm lenses. I suspect there might be something different in the manufacturing process of this very new lens, but until I take one apart and look inside (we haven't yet) I'm only speculating."
He has already run this data on 24mm primes, and in comparison, the 50mm primes are more consistent in general.
We have a habit of believing that newer lenses are more consistent than older ones. Roger's data -- granted, taken in a limited cross-section across many manufacturers -- would imply that this is not such a clear trend. In fairness, there was a very wide spread of simple 50s (Canon and Nikon budget f/1.8 designs) and very complex 50s (Sigma Art, Zeiss Otus 55) in this mix.

Canadian bird photographer Glenn Bartley has completed his review of the Canon EOS 5DS. As a bird photographer, Glenn requires a select featureset to maximize his number of keepers, especially with small avian creatures. As far as I know, Glenn shoots a lot with APS-C cameras such as the EOS 7D Mark II.</p>
<p>From Glenn:</p>
<blockquote><p>The 5DS has raised the bar and become the new king of high megapixel cameras. It is an impressive camera to be sure! Photographers whose primary and ultimate concern is resolution need look no further than the 5DS. If your photography workflow includes the best glass that money can buy, a very sturdy tripod, good technique, a solid post processing workflow and a fast computer this just might be the camera for you!</p>
<p>The reality is that most of us simply do not need 50.6 megapixels. Aside from the resolution increase the 5DS doesn’t really bring enough to the table to “force” 5D Mark III users to upgrade. Those of us wildlife photographers focussed on fast moving and small subjects would be wise to look past the incredible resolution of this camera to the more practical capabilities that it lacks (such as frame rate and buffer size). <a href="http://www.glennbartley.com/Canon5DSSetupandReview.html" target="_blank">Read the full review</a></p></blockquote>

Just come across this review of the 1DX and 5DIII vs the Nikon and Sony opposition.

http://www.digitalcameraworld.com/2015/05/26/the-best-camera-money-can-buy-6-top-dslrs/2/

The graphs and images have the 1DX and 5DIII leading the field for S/N for most of the way with the Nikon 810 at the "bottom of the pile". Above iso 400 (my usual range) the 1DX has the best DR with the 5DIII next and the "810 lags behind". The handling of the Canons is best, of course.

I have owned a Tamron 70-200 VC for about 15 months and had no problems. I mainly take photos of family activities, friends and my kids sports teams which I share with the school, sports club and other parents.
I encountered a problem when I was taking photos of our two family dogs chasing a ball being thrown by my wife. I had positioned myself so that the dogs would be running towards me -( I was going for the ears flapping type of shot ) my 5D3 was set to AF expand (9pts) at center point. AF mode in case 5(erratic movement and speed). I shot at various apertures and shutter speeds ranging from 1/1250-2000 in burst mode. the resulting pictures the dogs were blurred and I'm not really sure what went wrong. At first I thought it was motion blur, it was too much blur to be the F-stop but I went down to F7.1 just in case.
Could it have been the VC-the minimum shutter was 1/1250 so I didn't think so. Could I have just completely missed?????
I am a bit embarrassed by the result but I'll post a typical example of what i'm talking about :-[

Zeidora · Jul 10, 2015

Just started to play around with my 5dsr, coming from a 5d2.

On the 5d2, when live view is enabled, the mirror stays up even over multiple exposures (z-stacking). No mirror slap, no vibrations.

On the 5dsr, when pressing the shutter (via cable release, of course) in live view, the mirror goes first down, then back up, then takes exposure, hence introduces vibrations. I try to minimize vibrations by setting it to single shot silent mode.

In video mode, I can take images without mirror movement, but flash does not fire.

I could also go to mirror-lock up and set for 1 s delay, and adjust timing on Cogynsis StackShot. I routinely shoot 50-100 frames, so adding 1 second, plus Stackshot adjustments for each frame, adds a couple of minutes to a series.

Is there an elegant solution?

Chuck Alaimo · Jul 10, 2015

ok, couldn't find anything on this with a google search so asking! I just snagged a set of YN-600's and the transmitter (e3-rt). Love that it's just like the canon transmitter and I do like the AF assist. But --- here's an odd one.

One of the reasons I snagged them was because I wanted 2nd curtain sync. But...for some odd reason the YN flashes won't fire if the SS is below 2 seconds. My canons synced up nicely and had no issue firing with any SS. But the YN's won't. Wondering if this is just the hard limit on the flash or if there may be a setting I am missing. The manual is of no help, and all i can find for info just states that they can do second curtain sync. LOL, if 2 seconds is the limit, then fine, if I need more than that I have my canon flashes. Just odd that the YN's won't...any help out there?
