The older I get, the less I carry. The last trip saw me taking a Canon G12 for most of my picture taking, and a Nikon Coolpix 9100 for HD video and telephoto work. To this I added extra batteries, memory cards and a small table top tripod. Much easier on the back than a DSLR, flash, 4 lenses, full size tripod, etc.
If I were going to a national park or a once in a lifetime location, I would lug the weight, but for the other 95% of the pictures I take, light is the way to go for me. Although I must say, the new Sony Alpha 7 looks very promising. Small and light.
OK, Ladies & Gentlemen, herewith is my FAVORITE photographic Trivia Question:
What does the F in F-Stop mean?
The answer, is highly educational...
‘Still have an Olympus OM-2 with four lenses from 16mm Fish-eye to 200mm zoom Telephoto, plus adapters for an old 8” f/10 catadioptric telescope.
I used to shoot slide film including a lot of Astro when physically capable ... it’s probably been around 15 years since last use.
Canon 24-105
That's what I carry most of the time also. That 24-105 is a sweet carry lens.
This was taken with a Canon S2. It is a 5mp point and shoot. It just might be better for macro that some DSLRs with a macro lens.
Nice shot for a P&S.
It’s also called focal ratio.
Excellent. Where was it?
That is my back yard. He is sitting on a clothesline. The S2 will let you get so close that it is very nearly touching the subject.
I am hopefully going to eventually get a DSLR body with at least 24mp but as you can see, the number of pixels is not completely what makes a good pic.
This with a DSLR.
Taken with a Sony Alpha 200 or 230 using a Minolta Maxxum 70-210 lens. I was on my front porch when he came by.
Same Velvia. Ol Canon T90 with ton of lenses. And some assorted 35mm and mediumframe cams.
Squeeze the Velvia to 100, and you’ll see something interesting :).
AF-S NIKKOR 18-200mm 1:3.5-5.6GII ED
A little heavy to carry all day, but it will do everything your heart desires.
Do you have a shot of Half Dome from your back yard or front porch?
I have spent a lot of time in national and state parks but I am not much of a landscape photographer.

Same Nikon D200 with 18-105mm. Three shot HRD.
OK, the Trick-or-Treaters are gone...
The F in f-stop stands for fenestra, the Latin word for window.
Assigned in the late 1800’s with the development of adjustable diaphragm lenses, it was a designation meant to represent the amount of light required to make a perfect exposure on a film with an arbitrary speed, or sensitivity.
If you had a lens rated at f-1, the light from one window would be sufficient to make a perfect exposure.
The light from 16 windows would mean one would have to ‘stop’ down to the f-16 setting on the lens, reducing the amount of light through the lens, in order to make the correct exposure.
The confusion comes from the use of the word ‘focal’, which pertains to focus. An f-50 lens, has a focal distance of 50mm - the image is in ‘focus’, when the rear lens nodal of the lens is 50mm from the film plane. The closer the rear lens nodal (the high point of the rear lens element) is to the film plane, the wider the field-of-view - a 28mm lens is considered ‘wide-angle’, e.g.
