Hi Jools,
Experiences of an LF noob and self confessed gear junky.
Which movements?
I had an advantage here as my favourite and most used lens with the DLSR is the 24mm Tilt Shift where I'd use tilt to rotate the plane of focus for getting those extreme depth of fields we landscapers crave and vertical shift for bringing foreground elements into view while still keeping the camera level. I knew if I could do those two things with an LF camera I'd be happy, anything extra would be icing on the cake.
Horizontal shift I find useful if the composition isn't spot on and I don't want to have to reposition or rotate the camera but so far I've not found a great deal of need for it.
Which camera?
I guess I fall into the "Ebony Hugger" camp though I do treat it as a tool and not an ornament. I went MAD and got a used 45SU, there's no doubting that it's a nice camera but I'm very aware that I could get the same images with a camera costing maybe 1/5 the price.
Which lens?
My first priority was a 90mm as I knew its field of view (based on the short edge of the frame) roughly equated to the 24mm that I'm so fond of. If I could only have one lens then that's the one for me.
I've since added a 150mm, 210mm and 65mm. The 65 hasn't had much use yet due to heavy vignetting, I have a centre filter ordered which should hopefully cure this. The 150 and 210 also often stay in the bag due to my favouring the 90 but it's nice to know they are there if the need arises.
I'm sure you've thought of it but don't forget all the ancillary stuff, dark slides, changing tent, focus cloth, focusing loupe, shutter release cables, etc.
And then there's scanning, you might already be set up for this since I know you do MF film, but it's another cost and headache to be factored in.
For me personally, as indicated in another thread, metering has been a bit of a challenge but you have the advantage of already working with MF film so your all set in that respect.
When we meet at the end of March I'll have the LF camera with me, if you ask nicely I might let you stroke it
Paul.
