‘From Film Holder to Memory Card’ at TOP

4 Comments

The Online Photographer (a.k.a. “TOP”) is one of the blogs I follow regularly – lots of great thought-provoking posts show up there on a regular basis, frequently written by folks who know what they are talking about. Take a look if you don’t already follow TOP.

I enjoyed a recent article (“From Film Holder to Memory Card”) by photographer Charles Cramer in which he describes his transition from large format film gear to using medium format digital systems. My favorite example of Charlie’s ironic humor in the post is his “apology” to those who haven’t made the switch: “Note to my large format friends: O.K., I sold out—but I get to use zoom lenses!!!”

In any case, this post is another data point to consider if you happen to be one of those folks who is certain that great photography must be created using traditional film gear and processes. While there is absolutely no question that great work can still be done that way, it is equally possible to do wonderful photography with newer technologies… and, as Charlie illustrates, there are some things that can simply be done more effectively, less expensively, and with better results.

More Thoughts About the Pentax 645D ‘mini MF’ Camera

4 Comments

I responded to a post today in an interesting forum discussion about the new Pentax 645D “medium format” (or, as I prefer to call it, “mini MF” format) digital camera. This is a potentially game-changing camera. I has a 33mm x 44mm 40MP sensor and a body-only price of under $10,000. Its cost is far below that of competing mini MF bodies and a fraction of the cost of recent larger MF systems – and the price isn’t much above that of the high end full frame DSLR systems. While larger is not always better, for some types of photographers this puts a level and type of digital camera performance within reach.

In the discussion forum thread I referred to above, a writer had suggested that the 1.7x size differential between the Pentax 645D and full frame DSLRs would not be significant. In a sense he is right – it will not be significant to most photographers, and I surely cannot imagine why anyone would get one in order to make family photos to post on the web. However, I thought I’d share what I wrote concerning why I think that this might be significant for at least some photographers. My response (slightly edited) follows:

Photosite density is rarely the limiting factor when it comes to maximum print size from DSLR originals. As [the other poster] points out, “technique” stuff tends to be much more critical. Enlargement limits are more likely the result of stuff like camera movement, slight mis-focus, lens issues, etc.

I disagree that the size difference between the 24mm x 36mm full frame DSLR sensor and the 33mm x 44mm “mini MF” sensor isn’t significant. There are several reasons I feel this is the case: Continue reading More Thoughts About the Pentax 645D ‘mini MF’ Camera →
