I’m wondering if anyone out these hase much experience with third party tilt/shift lenses or adaptors. I’m hoping to use one for product photography (on Nikon Full Frame) rather than the arty miniturising effect. so I’m looking for something a bit more precise than a lensbaby. I found this Hartblei (link below) on google. Has anybody got any experience with these or can you perhaps recommend a (budget) alternative?
