There is an old rule: Save
on the body and spend on lenses.
This
rule was from the old film times where you could put the best film
into any camera. Today a digital camera is body and film in one.
This means you have to watch that your DSLR is good in terms of digital
imaging.
The reality is different: Oh, this camera
was so expensive and now I have hardly any money for a lens. Let's
start with a cheap do-everything
lens. Of course your dealer has many great bundles
in stock.
For some people this maybe just fine and they never find out the difference.
But many will find out that you cannot replace a good lens by a lower
quality one. At that point all your old photos had been degraded by
your too simple lens.
We checked out some of the Nikon options.
- AF-S 28-70mm f/2.8 (mounted)
- AF-S 18-70mm f/3.5-4.5G DX, D70 kit lens (right)
- AF-S 18-55 f/3.5-5.6 G DX, D50 kit lens (left)
Rule of thumb for zooms: More weight means better quality and higher
price :-) We photographed a very inspiring :-) brick wall to show the differences.
Be aware that this is not a scientific lens test.
All photos were taken from the same position, at about
55mm focal length, processed with RSE and EasyS Sharpening Toolkit
in exactly the same
way.

There is no real surprise here: The most expensive lens wins. This
does not really mean that we now want you to buy an AF-S
28-70mm f/2.8 lens as a companion for your D50.
Here are some more reasonable suggestions:
- Do not buy the kit lens AF-S 18-55 f/3.5-5.6
G DX and degrade
this fine camera
- Buying the AF-S 18-70mm
f/3.5-4.5G DX maybe ok
- Check out the Tamron SP AF 28-75mm f/2.8
XR Di lens (we use one
on the Canon 1DS Mk. II) for a ok lens and great value for the
money, all these lenses vary in quality from one sample to the
other).
- Get some good prime lenses and a good 55mm Macro. Prime lenses
most of the time beat even the top zooms hands down.
- Zooms with a ratio above 3-4x are rarely very good and/or get
heavy/bulky. A zoom is always a compromize and the larger the
range the harder to
get
right.
We took also some real photos today
We love to take test shots in Alviso (joined today by our friend
Jim Collum). Not only for the nice brick walls but for other photo
opportunities. Here are some shots from today (nice overcast):

Also in round two we had quite a bit of fun using
the D50.
Some Glitch: At some
point we got a bad exposure and the camera did not show a proper
f-stop but "--" instead. We have no idea what happened but a quick
on/off operation fixed the problem. We had issues like this with
other cameras (different manufacturers).
