comment How does a DX-format sensor support FX lenses?
A few DX bodies can auto-focus FX lenses that lack a focus motor - the body incorporates a focus motor and has a mechanical AF coupling in the lens mount. The early entry-level D50 can do that. Higher end DX cameras like the D7000 can too. Entry-level bodies like the D3200 can't. You can still use older AF lenses in manual-focus mode (obviously undesirable for many photographers).

comment What features should I be looking for a budget (under $300) camera for real estate?
It's worth mentioning that some descriptions of lenses on point & shoot cameras state the "35mm equivalent" focal length rather than the real focal length. So an actual 8mm lens on a P&S camera might be advertised as "28mm" (35mm / "full-frame" equivalent).

comment How to clean the focusing system?
+1 for rocket blower. In my experience, blowers with brushes are usually a menace, not a help.

comment Micro four thirds lens and camera compatibility
Isn't there a difference between MFT manufacturers in whether the image stabilisation is in the body or the lens? Some MFT lens/body combinations could have no IS?

Are you looking for an Arca-Swiss style clamp that works in a similar way to the Manfrotto RC2 clamp?

comment Why are 50mm Lenses Cheaper?
@mattdm, Oops yes, I guess you'd have to compare Nikon FX 50mm with Canon APS-C 35mm or something (given that Nikon-1 has no 18mm 1.8)

comment Why are 50mm Lenses Cheaper?
So called "full-frame" sensors are just cropped sensors from the perspective of medium format photography. AFAIK 35 mm on an APS-C sensor should have all the design adavantages of 50 mm on a 35mm sensor.

comment Do professionals use auto mode?
With the DSLR I use, in "program" mode, you can usually turn a control dial to adjust aperture and exposure on the fly. (In full auto mode, you can't)

comment Canon EOS 1000D gives Err 01, then phase-detection AF stops working
Live View disables phase-detection AF and uses contrast detection AF which probably doesn't need distance info from the lens.

Have you checked the gold electronic contacts in both the lens and the body are all clean and undamaged? Have you tried the lens on a different body or your body with a different lens?
