Wherever We Are Headed, We Certainly Are Not There Yet

Contrary to those who feel that with the introduction of multiple reasonably-priced 20+MP full frame DSLR camera there isn’t much room left for advancement and change, I think that the camera market is still truly dynamic.

One assumption that many make is that the high photosite density full-frame DSLR cameras will “take over” the part of the photographic world previously occupied by medium format (MF) film cameras. Several observations seem to support this notion. The resolution available from carefully used high end DSLRs with the best lenses certainly can compete with that of medium format film, and the arguable advantages of the larger format in terms of image quality would not be enough to convince many to give up the conveniences and lens choices of the best DSLR systems. Even those who might prefer to shoot medium format digital back systems – and I count myself as among those who are interested – are often not in a position to be able to afford the stratospheric cost of the best medium format systems, despite the fact that they compete with large format for image quality.

Some have argued that the costs of the high end systems cannot possibly come down. Some argue (falsely, I believe) that the high costs can not drop because, unlike the costs of computer memory, they are determined by factors that are not subject to scaling. Some argue that the market will never be big enough. However, these folks made the same arguments about the very types of cameras that are now becoming available in the DSLR market – the 20MP and higher full frame sensor camera. Not long ago these cameras cost roughly $8000 and were available from only one manufacturer. They now cost a third of this and are available from at least three vendors.

If you think this cannot happen in the medium format market, perhaps you need to watch a bit more closely. Recently Mamiya introduced a basic medium format digital system (admittedly not one defining the high end of this market segment) at a cost of around $14,000 if memory serves. This week Phase One announced 40 MP medium format backs at cost in roughly the upper teens ($15,000 or thereabouts) range. There are certainly higher priced backs available, but it was only a year or two ago that the 35MP MF backs were the high end – and cost perhaps two or three times this much.

It seems to me that these developments are moving toward bringing MF digital systems to a price point where some who might now get a high-end DSLR system may be able to instead think about going MF.

(Note added later: I just want to acknowledge that I do understand that there are reasons besides pixel dimensions – e.g. number of photosites/MP – to choose MF, and that I also understand that there are reasons other than cost to choose a DSLR. :-)

Welcome to Visitors from the 5dmk2 Blog

I noticed a spike in visits this morning that I’ve traced back to a reference in a post at the 5DMk2 blog at 1001 Noisy Cameras to yesterday’s post here about Live View on the 5DII. Thanks for the link, and welcome to visitors entering my blog world through the 1001 Noisy Cameras doorway. (And for those who arrived via a different route, if you are interested in the 5D2 and related topics, you should wander on over to the 5DMK2 blog once you finish up here.)

The two points I wrote about yesterday (the benefits of live view for depth of field preview and for shooting with very dark ND filters) are not the only benefits of the live view feature. For example, I earlier wrote about its value when doing night photography, and quite a few of my recent wildflower photos took advantage of it. Before long I hope to write up a more complete article outlining the range of uses for live view.

If this is your first visit to my blog, take a look around. I post a daily photograph (recent work has come from Death Valley and a number of central California locations) and the occasional opinion or news piece. You can subscribe via RSS (link near the top of the page) and members are welcome to post discussion messages.

(Shortly after posting this I got a message from B&H photo saying that they again have the Canon EOS 5D Mark II in stock, and unlike some other dealers they sell it with no markups at the list price of $2669.95.)

Canon EOS 5D Mark II: Two More Reasons to Love Live View

Yesterday I was at Point Lobos shooting a variety of wildlife, nature, and landscape subject. As I worked I found myself using the live view feature of my Canon EOS 5D Mark II very frequently – partly for reasons I’ve written about before, but largely for two reasons that I’d like to briefly mention.

Much better depth of field preview – Everyone knows about the small depth of field preview button on the body near the lens. Since the lens is open to the widest aperture when you focus you cannot tell what your depth of field will be until you push this button to stop down to the aperture that you’ll use for your shot. There are two problems with this technique: you cannot judge sharpness critically enough across the frame in the viewfinder and the viewfinder becomes incredibly dim if you stop down to small apertures like f/16. Put those two problems together and the usefulness of the preview button is diminished. However, when you use live view the camera automatically adjusts when you press the preview button and the image is still plenty bright to see on the LCD. Even better, you can zoom in to 5x or 10x magnification to carefully check sharpness. All in all, this makes DOF preview a much more useful feature when live view is used.

You can compose a photograph when using neutral density filters to extend exposure
– At one point this weekend I was using a 9-stop neutral density filter to make exposures of the surf with durations in the 10-20 second range. My usual practice is to compose the shot and, if necessary, manually focus without the filter attached. Once the shot is set up I attach the filter. Unfortunately, the filter renders the scene virtually invisible through the viewfinder. Recomposing or manually focusing requires removing the filter, making adjustments, and then reattaching the filter. I discovered yesterday that live view mode can display the image in the LCD even with my 9-stop ND filter in place, allowing me to make changes to the composition/framing or adjust focus without removing the filter

Canon EOS 5D Mark II: Live View and Night Photography

I have shot a few thousand frames with my Canon EOS 5D Mark II now. I’ve photographed a variety of subjects including a few days of rainy professional bicycle stage racing, several landscape subjects, and a productive evening of night photography with The Nocturnes at Mare Island Naval Shipyard. I plan to eventually write up something resembling a comprehensive report on my experience, but so far there hasn’t been time. With that in mind, here is a short piece on one new feature in this camera and my experience with it.

Among the photographic subjects that interest me is night photography, often of urban and industrial subjects, but occasionally of wild landscapes also. There are a number challenges to shooting in very dark conditions, but one of the more interesting is getting good focus in conditions where auto-focus often can’t find a target to work with and where it is too dark to manually focus. (I wrote a bit about this in a recent piece: “Hints for Night Photography.”)

During my last Mare Island shoot I discovered that Live View provides a very useful option for focusing at night. On the 5D II, the Live View mode raises the mirror and lets you look at a “live view” of your scene on the rear LCD. In very dim light the trick is to find something that might provide a manual focus target, center the rectangular LCD indicator over that “something,” zoom in to 10x magnification on this object, and then focus manually on the LCD image. I was amazed at the low light levels at which this works quite well. A vertical line in a wall, the edge of a window, a bit of cyclone fence, or a small light – any of these become decent manual focus targets using Live View.

When I started my Mare Island evening shoot, using this camera for the first time at night, I mostly did things the old fashioned way. By the end of the evening, in any very dim situation I was successfully and much more quickly getting good focus using Live View. I’m confident that night photographers are going to find that this is a very powerful and useful feature.
