Well, I've actually tried the lenses now, at least a little bit.
Of the wides, I've shot most with the Phase One 45mm. Pretty happy with the quality, I stitched for the the first time tonight - a three photo stitch of a local island at sunset using the RRS pano head came together really well in PTGUI (after lens corrections in LR).
As for the 28mm, pretty unimpressed with the lateral parts of the image on my first few shots - very smeared detail - but I've only taken a couple of shots so far so I'm going to see what I can do with this.
The 35mm hasn't really had a run yet.
The 80mm LS is solid, but a boring focal length. I used it for a very basic editorial shoot last weekend because it was reasonably fast and not a bad length for environmental portraits. Arguably something in the shots that you don't get with 35mm, but that could just be me trying to justify my 30K+ purchase! Is it better than the 85mm 1.2L on my Canon? Well, it's slower - and the P65 isn't quite in 5DMk3 territory for low light. Early days.
I used the 75-150mm a bit when I first got the system running last week, seemed nice and sharp but haven't tried it much in the last few days.
I have the Mamiya non-D version of the 150mm prime, haven't really shot with it yet.
Tried some sunset shots of bulk carriers down at the harbour with the 120mm Macro (the non-D, manula focus version). Pretty unimpressed so far, the 75-150mm was sharper but this could just be user error (manual focus).
The suprise so far is the Mamiya 210mm prime. Although it's not a fancy D lens, it seems nice and sharp. Pretty happy with the performance there, as good as lenses that cost me 10x its price.
That's the first thoughts on the kit. I haven't really answered my own question about wides yet as I need to do a bit more testing and shooting.
I've done a bit of fairly serious landscape shooting in the past couple of days but not of particularly attractive locations (my excuse for not getting 'the shot' yet).
The Cambo Wide RS is waiting for me at the airport so I should be shooting with that by tomorrow (unless I've forgotten some critical part). Will be interesting to see how the Rodie 45mm compares with the Phase 45mm. I must say I'm really looking forward to pointing a tech camera at some beautiful landscapes.
So Friday I'm off to the not-very-often photographed Millstream-Chichester National Park in the Pilbara (in the northwest bit of Oz). Unfortuantely, won't be able to use my 'the landscape was ugly' excuse there. Plan is to shoot sunrise on Saturday morning with the Cambo after sleeping out at a spot in the Chichester ranges I've used a few times before ('Panorama Camp').
One thing I did notice tonight when using the Phase 45mm is that there was some ugly green flare when shooting directly into the sun. Anyone know how the Rodenstocks perform when used for these sort of shots?
