comment Does this Camera Lens to Mobile phone camera interface exist?
It seems to be real but it also seems to be a way to get the bulk of an entry-level DSLR or CSC camera while losing any auto-focus, metering or VR features of your old DSLR lenses.

comment Which Nikon DSLRs have an autofocus motor in camera body?
You have listed some older DSLRs there but missed out the D50 which has an AF motor in the body.

comment Use Nikon D3100 in snow
See Flickr search for a practical answer. Plenty of people have used a D3100 at the top of that mountain.

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 How do you choose among different 70-300mm lens for Nikon DSLRs?
Handheld, you'll need a VR lens.

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?

comment Arca Swiss compatible quick release plate with a lever
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.

comment Canon EOS 1000D gives Err 01, then phase-detection AF stops working
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?

comment What are the important criteria in selecting a DSLR camera for conference photography?
Have you considered buying a faster lens for the D80?

comment Nikon D80 shutter problem
Could it just be the shutter release switch failing? I'd get a repair estimate.

The FAQ prohibits questions such as 'Which camera or brand is the "best"?'

comment What is the average lifetime of lenses, specially L lenses
Lens mountings evolve much more than they change. I think Canon only had one really incompatible lens-mount change change since the invention of the SLR. I believe most Nikon lenses that fit the original Nikon F in 1959 can still be used, without adapters, on this years cameras (at least in fully manual mode, the main problem would be incompatible meter coupling). The reverse isn't true as most modern lenses lack an aperture ring and older bodies don't control aperture.

comment How can I prevent blurred images when using a tripod?
Use the timer (+ IR remote + exposure-bracketing) and step outside the room?
