Pen F Hi-res test

I had a chance to run a test on the Pen F high resolution feature. These images are from the raw version of this shift capture mode. We are talking 10.3k x 7.7k pixels which is close to 80 Mp....

With a file that big you can make a 35 inch wide print at 300 dpi without upsizing it (!)

These are taken with the camera resting on a solid surface with a 4 second silent shutter delay - though I used ISO 1600 due to the low light levels. This is with the 20mm f1.7 at f5.6.

I used small amounts of sharpening and noise reduction in Adobe DNG import/Elements. I prefer to see noise rather than too much smearing.



And a 100% sample.



And a second shot



Incredibly, you can almost read John Kimber's name on this monument...



Yes. It does work. Reach for your sharpest lens though, and hone your technique. Everything matters at this resolution..

This is where I regret selling my old 4/3 50mm macro. Even now this is still rated as a monumentally sharp lens :-)

Pete

Re: Pen F Hi-res test

Pete,
Excellent examples of HR mode.

Any idea who installed the church lighting - so that we will know who not to use in future?

Eh? What? We paid good money for that. And we were lucky they had it in the back of their white van, all ready to fit and all...

Messrs Heath and Robinson I suspect .

Impressive results though - would certainly show up a less than brilliant lens!

Re: Pen F Hi-res test

All in all its very impressive. The first shot looks even better cropped into portrait as it focusses your eyes on the run of pews going forward rather than side to side. You picked a very good angle for the second shot but yes the grandeur of the place is brought down by those electric lights that should have stayed on the van.

Re: Pen F Hi-res test

Yes, not intended as an arty shot really, just something with lots of detail to test the camera HR mode. It turns out that the 20mm is not too shabby at all. I should do this all again with the 12mm and the 45mm.

We are about half way through replacing the old Halogen downlighters with modern LED stuff.

I absolutely stopped going up The Big Ladder to replace bulbs quite a few years ago. That was when I found all three wires (L, N, E) would light a neon tester even though the circuit breaker was off. (Mineral insulated cable cable plus some damp)...

Re: Pen F Hi-res test

Surely you would have got a much better result sticking with ISO 200.

My hires shots are always at ISO 200. You need the completely stable surface anyway, so why not have a longer shutter speed?

Yes, that is quite right, and to do it properly I would take my big manfrotto .. but on this occasion I was surrounded by electricians so I opted for a click and try approach. When they are finished I will go back and do it all again

Re: Pen F Hi-res test

I only recently got a Pen F. I did a quick test of high res and it works very well.
