D7000 - D7100: worth it?

Quote:I've put my D7000 up for sale with a 50 mm lens that I own on ebay. I've set the reserve in such a way that if the camera sells, I've re-couped the cost of a D7000 as it currently stands.

How many people are going to buy a secondhand camera on ebay for the same price they can get a new one. Dont forget you will have fees to pay to ebay and fees to paypal if it does sell.



It has a lens with it, so it would sell for higher than the price of a body alone (and it's a lens I'm willing to part with as I haven't used it a great deal lately). I've set the reserve high enough so that should it sell I won't be left significantly out of pocket.

I have thought about it. Smile

its worth a shot - it always amazes me how people get bid fever and pay more for a sh item than buying it new.

A sh item, is it? I see you're a Canon man. Grin Tongue

I do know what you mean, however, some people do get rather carried away with themselves.

On reflecting a little, I'm going to take some time to think on this. My D7000 has been a brilliant camera and I seem to have been lucky in that I got a model that doesn't suffer from any QC issues. I may be getting blinded by the lights a bit - I probably don't really need the D7100.

Need??? What has that got to do with it?
I am sure the 7100 has got some shiny new lights or something that you haven't seen before.

Quote:The crop factor change from 1.5 to 1.3 is interesting

It can be particularly useful for video. Video uses a lot less than 24MP for each frame, and cropping video after recording is a bit of a nightmare.

One snag with the 1.3 crop factor is that some wide-angle lenses will vignette.

Our old Kodak DCS760 bodies were 1.3 crop factor and the 17-55 Nikon lens gave distinctly dark corners at the shorter focal lengths. You'll need to check a DX lens before purchase.

I think you have a misunderstanding. The 1.3 crop factor is on top of the 1.5, giving an overall crop factor of 2. This additional 1.3 crop is an additional shooting option. At full resolution the D7100 is a standard 1.5 crop factor DX format.

Think of it as the camera having an almost m4/3 crop option. I know aspect ratios are different.

Save your money, Wait 5 years, 7400 would be awesome compared to nowdays model.

For those going to Focus, Nikon are holding two seminars most days about the D7100.
I will be having a close look at it teamed with the 70-200 f4 and a TC 14e for possible macro work to replace my 70-180 Nikon macro.

Do you know what magnication ratio and minimum focusing distance you'd get with the new 70-200 f4 and TC 14e? That could be very useful for flying dragonflys etc

Nikon quote 3 feet 3 inches minimum focus distance for the 70-200 f4.
The close up magnification of the 70-180 is .37.
This is about a 2 inch wide subject on FX, close enough for most dragonflies. The focus distance is about 15 inches but the front of lens hood to subject is only 4.5 inches which is too close for many insects.
The close up magnification of the 70-200 without a converter is quoted as .274.
I am expecting the magnification with a TC14e converter to improve to .38 at a focus distance of more than 3 feet, which will be much better for dragonflies.
The distance from the front of the lens hood to the subject should be about 2'3" (presuming this lens does not extend in close focus) which is good for dragonflies.
Filing in a gap the 200mm macro covers a 2 inch wide subject on FX at about 2 feet focus distance with an in-between lens hood to subject distance of 11 inches. The autofocus with this lens is some way from fast.
Like you I am interested in subjects such as dragonflies in flight. I am taking my 70-180, my TC 14e and a measuring tape to Focus for a comparison.
Autofocus extension tubes on a 300 primes would be even better for dragonflies in flight but as yet, unlike Canon, Nikon do not make autofocus tubes.

This detail is right but I miscalculated.
The 70-200 close focus ability is 5.5 inches wide on FX at a very useful 3 feet 3 inches. This reduces to 4 inches wide with a 1.4 converter.
The figures for DX are 4 inches without converter or just over 2.5 inches with converter.
These figures are very useful for some flying insects though the 70-200 does not have as great a potential magnification as the much closer focusing 70-180.
The 70-180 does 5.5 inches wide at a focus distance of 2 feet 3 inches and a lens hood to subject distance of 16 inches.
The autofocus of the 70-180 seemed slower as expected being f5.6 and screwdriver AF.
The 70-200 does not extend when zoomed and the build quality and finish looks similar to the 24-120 f4.
The 70-200 hood and tripod collar was not available.
Due to by far the biggest crowds I have encountered mid week at Focus handling time was restricted.

So I decided not to bother with the upgrade. My D7000 serves my needs wonderfully and whilst I'm sure the D7100 is an admirable piece of kit, upgrading for the sake of it is stupid.

Spent some of the money that would have otherwise gone towards the newer camera on a new 50 mm lens for my Mamiya, which is a great lens.
