#1. You can get a combination of Kit lenses, usually its like 18-55mm and 55-200mm/55-250mm. Its okayish combination but i would rather suggest spending a bit more and getting Tamron 18-270mm as its a cracker of a lens and isnt that expensive.
If your going Nikon then no point getting 18-105mm, specially if you will be buying 200mm. Remember due to crop factor your 18-200mm lenses will give you 27-300mm FOV.
#2. Hoya are good as long as you get originals. Cokin and Lee are the best, they have the biggest range of filters and in the long run they turn out to be cheaper than circular filters
#3. Don't get a crap tripod to save money, even a lil bit of air will ruin your shots, worse it can knock off the DSLR+lens. Get a decent one from Manfrotto or get a Manfrotto copy, they are fairly cheap these days. I suggest checking out ebay for cheap knock offs.

Infact, I feel in 5 years every camera in the D-SLR range will have full frame as standard. |
Not going to happen. APS in digital has inherent benefit, sensor price. Sensors are harder to make as size inreases. Medium Format sensors are still in the range of 4 figures even when bought in thousands.
Similarily Full Frame has a draw back, higher price, higher error rate during manufacturing, lenses need bigger imaging circle which directly adds to the price of optical glass which is already too expensive and tidious to make. Just watching "Canon Lens making Technique" makes it clear why lenses are so expensive.
But all this is just BS and doesnt hold a "2cents" worth when it comes to consumer trends. At the moment trend is completely towards compact cameras. Consumers want compactness which cannot be achieved with Full Frame Sensors for obvious reasons.
m43 system is taking off like a rocket because people wanted compactness with powerful feature set and to be honest we have no idea what will consumers decide as the future.

1. Upgrade cost to a full frame DSL
2. Upgare cost to Dedicated lenses for full frame
3. reduced price for existing lenses in used market, which could delay upgrdation by about 2 years (Assumption) |
Dx lenses does not cause vignetting, they cause black space around the imaging circle.
This is what happens when Dx lenses are mounted on a Full Frame body (i cannot believe i am linking ken-lol-well). The only solution is to use Extension tubes which basically means, lens will be slower to use.

Like the teleconverter which enhances lens performance, can a concave-convex attachment be manufactured which first disperses and then converges light accurately to aviod vignetting on a full frame. Well there is certainly need for such a system.
Experts, what are your thoughts, are there unsurmountable technical challenges?
Best, |
Why will companies make a $50 adapter to adapt a lens when they can sell a $1500 lens.
Teleconverters don't enhance lens performance, if anything they decrease lens performance.
Vignetting is very easy to correct as long as RAW files are available.

Now i am baffled

, why will they implement LN2 when they can implement Phase Change system which is easier+cheaper+better for rapid cooling. Plus the biggest benefit of high grounds mean easier to implement and less maintenance. Also LN2 will cause Leidenfrost effect when used with running CCD's.
The biggest benefit being idiot proof and almost no work hazards.

i ask because i have been building my lenses (17-40, 100 mm. A 300mm is on the anvil) with a view to moving to a full frame towards the end of the year. |

Do you still want to take even a single comment from him seriously ???
