I photographed many times with the 645D hand held, and I enjoyed it a lot. Having said that, I do enjoy shooting the 645Z this way a little more, simply because it's more responsive, and the greater range of ISO provides more exposure options in available light. Either way, I wouldn't call it "last resort". If David Burnett could shoot the 2012 Olympics with a 4x5 Speed Graphic hand held, then I guess we can photograph hand held with a Pentax 645 digital rig. :)

Most of my photography is done on a tripod, but I grew tired of carrying multiple systems awhile ago. I'm slowly divesting everything outside of my Pentax 645 kit. So if I want to shoot indoor candids, street, events, wildlife or whatever else, the Pentax is what I reach for because it's the camera system I want to photograph with, and most often I don't have any other "large" system available. (I do have a Sony pocket camera, and a camera phone.) If you use anything enough, you tend to get good at using it to its maximum potential, within whatever relative strengths & weaknesses it has.

Depending on lens, available light, shooting technique, etc. the D (or Z) may or may not produce the highest resolution / lowest noise images of which the camera is capable. That might be perfectly fine; not all photographs need the highest level of technical quality to achieve the purpose.

Maximum ISO is whatever I need for the exposure I want. Noise tolerance is a personal choice. Though normally I preferred a lower ISO, I shot up to ISO 1600 on the D many times with results usable for what I needed. I try to do more or less the rule of thumb of keeping the shutter speed at or above the reciprocal of the focal length. With the caveat that this rule of thumb is from 35mm full frame equivalent focal lengths, and assumes no stabilization. And the further caveat that sometimes blur, very shallow depth-of-field, or other characteristics are creative choices rather than flaws...

Am in Pembrokeshire starting a photographic project for my own benefit. All went well right up to the end of the day when Friday 13th caught up with me. Have been on the edge of 200 feet cliffs with a bit of wind. Tripod nice and secure, until I had finished shooting. Put tripod down with camera on it so I could have hands free to pack things into my car. Then *CRASH* tripod falls to the floor and camera flies off it. Camera is fine, but 28 - 45 looks to be mangled. Gutted. My favourite lens which takes about 80%+ of my shots.

Here are some shots I took before it happened. All of course with 645Z and 28 - 45

the 67 105/2.4 I have does not have a very close minimum focus distance so I add my shortest extension tube for small objects that are close. Here are are examples using the extension tube, also wide open aperture as before

fwiw, a couple of test shots of the 67 SMC105/2.4 on the 645D. Sorry for the subject matter, it was Christmas. Both wide open. For closer focus, i use a short extension tube and have shots to share if anyone is interested.

SMC pentax 645 300mm - MF vs AF?
Posted By Thomas

I use a 400mm FA on a 645D and a 600mm A*; the AF is a substantial advantage for birds. Here's an example; no way for me to get this with the MF version.

Dear friends,

Long time no see! For those of you who are curious, here's a link to a "micro-review" I've done on the Dynamic Range offered by the 645Z. I wrote very little, choosing instead to provide interested users with my original DNG file for examination.

I hope everyone is doing well and taking lots of pictures!

What you are saying is that for a cheaper price you are prepared to accept some compromises.

I am saying that I don't want any compromises and are prepared to pay for it.

Two different requirements.

Everything as expected, so far. I am sure that an excellent lens in this range (with this I mean something better than the 33-55) will be heavy and large. I also think that such a lens is a much needed addition to the line-up and I'd be happy to shell out $8K for it. Folks need to get used to the concept that if Pentax/Ricoh are supposed to produce great lenses they will cost money. And I am not interested in second rate lenses for the system as it makes little sense.

Wow - what a creative (and somewhat dangerous sounding) shot! Love the sparks with the coke - very unique. Lovely shot and nominated.
