Best Buy has incredible deals on occasion. I got a comparable deal on a 80-400 lens a couple of months ago. No one in the store would explain the reduced price, but there it was--for about a week, and then back to the normal price.
The 610 with a 28-300 is a great match. Congratulations.

That's about as good a deal as I got on my Canon 6D with 24-105 f/4L from Amazon almost 2 years ago. (I'm not going to get into the relative merits of the two brands. One brand will be a bit better for a bit and then the other will get ahead, ad infinitum.)

Ah, my cf tripod...still performs as new (bought in 2010).
For telescope tripods, there are things called 'Shake-Ender Pads' (made by Celestron). These are a set of three discs. Each disc is a set of nested molded rigid plastic cups with a molded energy-absorbing foam layer between them. They work by dissipating vibrational energy that would otherwise bounce back upward from the ground. The downside for routine photographic use is that one typically sets a telescope tripod up once and uses it all night without moving it, unlike the way a photo tripod is normally used.

Excellent description of the differences of the materials.
Thanks.

In general, stiff composite materials (like carbon fiber tubes) damp high frequency vibrations better than uniform materials (like metal tubes) because composites are made up of at least two different substances, the 'matrix'; which is usually some kind of resin, and one or more kinds of fibrous materials (commonly silica-- glass-- fibers and or carbon-- graphitic tubule-- fibers); each of which has a different 'speed of sound'. This nonuniformity smears out sound and other vibration waves and eventually attenuates them.
Carbon Fiber is enough less elastic than pretty much any metal that would be used for structural purposes that it, and enough stiffer relative to its weight that a given CF tube will tend to try to vibrate at higher frequencies than an equivalent-sized metal tube-- which get damped by the effect described in my first paragraph.
There's a reason that you see wind chimes made of lengths of metal tube all the time, but you won't see any made of CF any time soon.
BTW, the strongest materials used structurally by plants and animals-- wood, bone, tooth enamel, and the various materials used for shells, scales, and the like, and the tensile structures used by kelp are all composites.

UPDATE: Amazing what you can learn by reading your camera manual.
I reset the AE-L/AF-L button on my MB-MD11 vertical grip and have BBF there as well now.
Also set up other custom functions like reducing exposure as the D7000 seems to over expose normal and bright scenes and fine tuning AF with each lens. Experimenting with Auto ISO as well.

I'm surprised that you have to teach the buttons on your vertical grip what you want them to do separately from the corresponding buttons on the body itself. I suppose it gives greater flexibility, but who would want the flexibility there-- having to remember that both buttons marked the same way don't do the same thing would be a major pain in my butt.
Canon doesn't make one do that.

It's not a choice between cellphone (as camera) and non-cellphone camera for some people. That expensive smartphone is doing a lot of other things that don't involve photography-- and for some people the phone camera is good enough relative to a little p&s.
But what do I know? I'm not the target audience. I run around with a dumb flip-phone and a Canon 6D and some lenses in a backpack most places I go. . .

I still have 5 OM bodies mothballed, with a pile of lenses. No, I'm not planning to sell them. Got Photodiox 'chipped' adapters for a couple of the lenses to use with my Canon DSLRs.

i agree with this person's post. a sensor cleaner is the best and safest way to remove dust.
another thought, when changing lenses, hold the body in a downward position. that will help a lot.

Yes and yes.

I am not too sure we are talking about the same thing. The only issue I am having is the size limitation imposed by Ugle Hedgehog. This site will not allow you are me to upload files that exceed as certain size. This has nothing to do with my computer. Is this what you were referring too?
Oh, sorry. UHH does have pretty severe limitations. I'm guessing that the best way to distribute the files would be on DVD, by mail.

It would not be patentable. That sort of thing-- altering a lens design to accomodate a smaller film size at a smaller field of view-- has been done for decades.

Don't think it is a RAM thing...I have 16 gig. The file FIT file is 440mb and the TIF is 230. That seems to be the issue.
With 16GB RAM you shouldn't have problems with files of less than 1/2 GB unless you have a bunch of them open.

Square or rectangular, inside a circle whose radius is comfortably larger than its diagonal.
