Canon EOS 5DsR Quick Update

If you are a Canon-using photographer you are almost certainly aware that Canon has released two new DSLR cameras in the 5D series, the 5DS and the 5DS R models. Both provide approximately 50 megapixels (MP) of sensor resolution along with some other improvements. The cameras seem to be an excellent next evolutionary step for Canon photographers who can use the additional resolution.

I have the 5DS R model and I’ve had the chance to photograph with it twice as of this date. I have been asked to share my thoughts on the camera, but it is still a bit too early for me to write a full report — I want to make more photographs with it and I want to make some very large prints from the files first. Meanwhile I can share a few things: Continue reading Canon EOS 5DsR Quick Update

New Canon EOS 5Ds In Stock

Canon EOS 5Ds DSLR
Canon EOS 5Ds DSLR

As of this morning, the new Canon EOS 5Ds is in stock right now at various dealers, including site-sponsor B&H Photo.

The 5DS (including the 5DS R variant) is Canon’s new 50.6MP full frame DSLR. The camera provides the highest resolution sensor of any current full frame cameras, along with several other improved features.

(The 5DS R model cancels the anti-aliasing filter that has long been a standard feature of digital cameras. The “R” model is back-ordered, so those who want that version and don’t want to wait should consider putting in an order.)

(You may use the links in this paragraph to order/reserve either the 5DS or the 5DS R from site-sponsor B&H photo. I have reserved mine — I’m going with the “R” model.)

Looking at Canon 5Ds Raw Files: Noise and Dynamic Range

(Note: The images were not included in the original post, which instead included text links only. The images are now part of the post.)

I just took a break and had time to play with a Canon 5Ds raw file that I found on the web. (Anyone wanting to look at files from the 5Ds should head on over to that link right now — there are something like 90+ files to look at.) It was made with the 5Ds at ISO 100, f/8, 1/400 second. It isn’t clear what lens was used, but it appears that it could have been either the 50mm f/1.8 STM lens or the 24-70mm f/2.8 II.

I opened the file in ACR. I made no adjustments to curves, color, etc. I let ACR automatically correct for CA. Default ACR sharpening used at 15 with masking at 50.

I brought the converted file into Photoshop as a smart object to allow for non-destructive re-editing in Adobe Camera Raw (ACR). I confirmed that shadow areas along the waterline of the boats have luminosity values of 0 — I did this by checking the Lab color representation and watching the L value, which hits 0 in several spots. The general area is shown by the rectangle in the following image: Continue reading Looking at Canon 5Ds Raw Files: Noise and Dynamic Range

Canon EOS 5Ds and 5Ds R Release Near?

Several months ago Canon announced that it would release two new high-megapixel DSLR cameras in the 5D series, the 5Ds and the 5Ds R in June. June is now only a couple of days away. Although I don’t have any inside information, there are hints that the release could come as early as the first week of the month.

I think there will be a large pent-up demand for these cameras from Canon photographers, some of whom have watched from the sidelines as companies like Sony and Nikon have introduced higher MP camera bodies. Those who want to get early copies can preorder — here are links to site-sponsor B&H:

The primary value proposition of the new camera series is the 50.6 megapixel sensor. This is a higher sensor resolution than on any other current full-frame DSLR, and it more than doubles the number of photo sites on earlier Canon DSLRs. For photographers who make big prints from DSLR photographs, and especially for those who work with a great deal of care and focus on subjects in which image resolution may become critical, this will likely be significant advance.

Canon 50MP 5DS Body, 11-24mm Lens, and Updated Rebel DSLRs

I’ll start with a list, and I’ll add a few comments below.

You may feel differently, but the most interesting announcement to is that of the two versions of the EOS 5DS, a 50.6mp full frame DSLR that seems optimized for image quality. While not everyone will need 50MP in a full frame body, some of us will most certainly benefit from sensor resolution that more than doubles what was previously available from Canon. There are two models, the 5DS and the 5DS R — the 5DS R doesn’t apply anti-aliasing filtering. This has the potential to maximize image sharpness for certain kinds of photographers, and the potential risk of some moire artifacts in photographs of certain types of patterned subjects. The cameras are supposed to begin shipping in June, and I plan to get one — most likely the R model.

For those who like really wide angle zoom lenses, the EF 11-24mm f/4L lens is arguably going to be king of the hill. Early reports are that it is optically excellent, and 11mm is 1mm wider than the excellent 14-24mm Nikon f/2.8 zoom. This lens (as noted above) can apparently now be pre-ordered.

The Rebel T6i and T6s are the newest updated models in the family of consumer Rebel DSLRs. These are fine cameras at a good price, and Canon will no doubt sell tons of them. They use 24mm cropped format sensors, and they are available in body-only version and it kits that include a basic zoom lens. The T6s is said to have a few more “advanced” features added.

Canon EF 100-400mm f/4.5-5.6L IS II Lens — A First Look

(Note: Updated 12/24/14 to add thoughts about “who should buy” this lens.)

Canon 100-400mm f/4.5-5.6L IS IICanon EF 100-400mm f/4.5-5.6L IS II

Canon recently released the successor to their venerable 100-400mm telephoto zoom lens, the new EF 100-400mm f/4.5-5.6L IS II lens. I have relied on the older model for some time now… but my copy of the new lens arrived a few days ago. Now that I have used it for a day of wildlife and landscape photography I would like to share some first impressions

First, a few technical details. The new lens covers essentially the same range as the older model — a focal length range of 100mm to 400mm and a variable aperture range of f/4.5 (at 100mm) to f/5.6 (at 400mm). Both lenses use a zoom mechanism that extends at longer focal lengths. However, there are some technical differences:

Canon 100-400mm f/4.5-5.6L IS II Lens Announced

(Updated) Canon has announced the long-rumored replacement to the venerable 100-400mm L lens. It is the EF 100-400mm f/4.5-5.6L IS II.

The lens it replaces has been a very valuable “go to” lens for many photographers who wanted more reach, a reasonably small package, good optical quality, and the flexibility of a zoom. I’ve been an enthusiastic user of the older version for some time now.

Recently Canon has updated or augmented their lens line-up to improve the offerings in certain categories. For example, earlier this year they introduced their ultra wide angle zooms by adding a new EF 16-35mm f/4L IS lens. That lens has been a real success, not only adding image stabilization to lenses in this class for the first time, but also providing excellent resolution across the frame — more so than either of the lenses that many photographers used before it was introduced.

For some time, many have felt that there was a lot of potential for updating the 100-400. Although it is good performer in many ways, there has been room for improvement. More modern IS systems can provide up to 4 stops of stabilization, while the older lens only provides perhaps two. The older lens has good image quality, but it could be better in keeping with more recent lenses from Canon. In fact, rumors about the introduction of the updated 100-400mm zoom have been floating around for years.

We don’t know what the optical performance of the new lens will be yet. As I write this I have seen no real reviews. (I have seen some “reviews” that are mostly lists of specifications and speculation.) When we do see them, it will not surprise me at all if this lens provides valuable improvements in the same way that the 16-35mm f/4 has. Here is some of what we do know from Canon specifications:

  • Rather than the “push-pull” design of the earlier lens, this one has a more familiar rotation ring to change the focal length.
  • As was the case with the older model, the front of the lens extends as you zoom. This means that the lens is more compact when packed.
  • Image stabilization has been updated to provide up to four stops of stabilization — especially important with longer focal length lenses.
  • Other features include 9 blade diaphragm, the familiar 77mm filter thread diameter, and more.

The list price of the lens is $2,199. That may seem like a lot of money, but if it provides the sort of image quality we all expect it is actually a rather good deal for a lens with these capabilities.

Update: I have now had a chance to look at the MTF charts for the new lens (available at the Canon web site) and they suggest that the new zoom should be a very good performer in terms of image quality. The chart suggests better image quality than the existing 100-400 (which is quite decent) and the 400mm f/5.6 prime.

I expect that this lens will be in short supply at first — for the usual reasons related to any new product introduction, but also because of a pent-up interest in the update. The lens has been announced but is not yet available — though you may preorder it if you want to be first to get one.

As for me, there is a very good chance that I will get a copy of this lens before too long. In fact, I’m leaning more and more towards placing a pre-order — something that I rarely do.
