MF SLR - 28mm MF SLR lenses from Mamiya and Hasselblad
- Advantages: Autofocus, Autoexposure, Through the lens composition. By far "easiest" option. Easy to hand hold.
- Disadvantages: lens quality is good, but not excellent (much better if using a sub-frame back like the IQ140 since you don't see the extreme corners). No movements (other than in post-processing).
TECH CAMERA - 23mm to 35mm lenses from Schneider and Rodenstock lenses on a tech camera
- Advantages: Best lens quality, bar none, including lenses which show nearly zero distortion (though some, like 23HR and 32HR do have notable distortion). Very durable/traditional/simple/tactile shooting experience. Great for stitching. Some are hand holdable.
- Disadvantages: requires most expertise/learning-curve to operate. Focusing/composition options are limited (some ground glass options, sliding back options - many users opt not to have any through-the-lens focus/composition option). Requires lens-cast correction.
VIEW CAMERA - 23mm to 35mm lenses from Schneider and Rodenstock lenses on view cameras
- Advantages: Largest range/selection/independence of movements. Most traditional and most compatible with film workflow (if you want to shoot both film and digital). Can be (relatively) inexpensive on pre-owned market.
- Disadvantages: Large/heavy. VERY hard (some would say impossible on a practical level) to get proper focus, even on a precise view camera. Requires steep learning curve. More or less limited to tripod. Requires lens-cast correction.
H-CAM - 35mm dSLR lenses using an H-Cam, but only those with a large enough IC like the 17TS and 24TS
- Advantages: Less Lens Cast than a tech camera, electronic control of aperture/shutter-speed, absolute widest available (17mm on a FF back).
- Disadvantages: movements limited to what's available in the lens. Ideal stitching requires tripod lens adapter (so lens stays stationary). More or less limited to tripod. Larger/heavier than smaller tech cameras.
Obviously this list of advantages and disadvantages is a quick summary. Like any summary there are many exceptions and points that could be intelligently disputed and there are many other factors to consider. So please don't take anything above as "absolutes" just meant to help you introduce you to the range of options and generally why people opt for one or the other.
A good dealer is your best bet (in my highly biased and self-interested opinion - see signature) to get into more of the nitty gritty advantage/disadvantages and see/test/explore these options and decide which one best fits your needs/wants/tastes/budget.
