I think the challenge with the off-center auto-focus points is that the light gets diverted with a sub-mirror and that mirror is quite small, so light can be dispersed only so much, thus the “outer” focus points get very little light and do not perform as well. Assuming that AF point spread of something like the Canon 1Ds3 is about as wide as it…[Read more]

Because they had to, and were better poised to do so.

The traditional moveable multi-point solution found in 35mm SLR/DSLRs is more manageable due to the smaller AF area needing coverage … but even then, it is grouped toward the center. The advantage is you can set a specific outer AF point and leave it for multiple shots … yet even with…[Read more]

I'd love to have a True Focus type mode on the S or any dSLR. It's one of those ideas that is so simple, that you wonder why it was Hasselblad to do it first.

I also use the Giottos bulb … but only after pumping it a couple of times to get rid of any dust it may have ingested. I turn the camera sensor down so any dust gets dislodged and falls away from the sensor.

However, the best tool to date, the one I use on all my cameras, including MFD sensors, is the Arctic Butterfly brush. You run the…[Read more]

Lets be fair here Josh … the True Focus on the Hasselblad H4 camera isn't “theoretical”, it is a working fact, and it works very well.

As I understand it, Hasselblad has further refined it in the H5 camera to account for any lens field curvature.

The TF feature promotes creative off-center composition with confidence even with fast…[Read more]

great examples of lenses. The grill and polishing man are massive camera shake for sure. I think ISO 640 is useable as you suggested, 320 is more than ok.

Really appreciate the examples i hope to give back also when i start shooting.

I will be testing from friday – sunday to see if it can be hand held. I know its not the best and tripod is better but I have to try based upon my requirements.

As I've spent more time…[Read more]

This function works great to check composition, expression, lighting, etc.

I'm curious what drew your attention to this post? I tried to make it attention getting but perhaps I could do better?

So now tell us your 35mm story please

Hahah yes the M is lovely if what you shoot can be captured by the manual focus or pre set focus.

I have access to an S2 at a no brainer price, not as no brainer as the D800E and that would certainly be a back up given I use Pentax lenses on the Nikon now. I was quite shocked at the lack of DR.

The Leaf and Phase seem to recover…[Read more]
