Hi Victor I have a similar type of image taken at f7 I'll upload it later tonightYair,
Thanks for the upload.... You are at the outer edge of the f/stop range for my comfort. I usually try to stay under f11 but f11 may be the magic f/stop for the 55.
Victor
Victor,Jack,
What f/stop delivers acceptable results for you with the 45D? f11 (as an example) is stopping down almost too much for me...I would really like to shoot at 5.6 or f8.
Yay! Mine too! I used mine on a commercial job recently, photographing a church, and I'm VERY happy with it.Victor,
Well.... I just met up with Guy and Bob for the workshop and Guy asked us to test his copy of the 55LS.. We did and his copy is a freaking laser, so they are out there. Both Bob and I are rethinking it. To clarify, his copy is sharp corner to corner at f5.6 on the P65+, a laser at f8 and 11, and honestly quite usable wide open at f2.8. Pretty much parallels the 80...
Guy, wouldn't you be concerned that the 47 and 35 might have the same banding issues as the P65+ when shifting?If I actually bought the 80mpx IQ 180. I may just go with a Alpa with 47 and 35 or something like that for the wide end or see what is next in the Phase lineup.
I have the 55LS and mine is tack sharp edge to edge on both my P65+ and Leaf Apyus 12. Optimal apertures appear to be roughly f7 to f11. Smaller then f11 seems to show diffraction softness.Victor,

Ed, I use both 47 and 35mm's on my Alpa STC in my architectural photography practice. The banding you are talking about is a product of the angle at which light strikes the sensor when using symmetrical lenses.Guy, wouldn't you be concerned that the 47 and 35 might have the same banding issues as the P65+ when shifting?
I had one of those "I can't believe I got this" shot with the 24XL that had banding which I ended up cleaning manually. A royal pain in the backside for sure.

And FWIW LCC tools in both Capture One and Leaf Capture clean any of these artefacts nicelyEd, I use both 47 and 35mm's on my Alpa STC in my architectural photography practice.

I can't change the laws of optics and physics even when I use all my magical super-photographer powers, so I compromise - use some shift and (gasp!) tip my camera up or down a little, then use some correction in photoshop. With my P65+ and Aptus 12 there are so many pixels of data available that one does not see the artefacts of interpolation that one sees when using photoshop to correct convergence in DSLR files. This is one of the areas where having a good relationship with the Megapixel God is a huge blessing.
This is why the marriage of a huge sensor and a technical camera like the Alpa is the weapon of choice for pros.
Hope this helps...
Cheers,
The issue I've had is that , for example, with the 35mm on the Alpa with the Aptus 12, when I get beyond 8mm shift, the lenscast is more severe than LCC can correct. It is in situations where I need more shift than this that I resort to tipping the camera and correcting perspective in post, whilst still using modest shift.And FWIW LCC tools in both Capture One and Leaf Capture clean any of these artefacts nicely
