OK, I didn’t get that across, let’s try again…
Landscape - as wide as possible, I found the 28-85 to be too long for a lot of what I wanted to shoot, and the 20mm is very good for landscape
Table-top/product photography - 85mm
Portrait 130-150 I can’t imagine having a relaxed subject if you’re in their face with an 85mm - the longer lens lets you be far enough away.
The 200mm for aircraft was assuming both
- General aviation subjects
- on the ground
If you want in-flight, it comes down to how large is it and how close you want to get?
“critters and landscape” are my usual subjects - the 28-85 was the walk-around I used for everyday shots, but it won’t even come close for critters
Critters need at least 100mm (at the zoo, with pets, and other close-up situations). Wild ones need 200-1000mm-10,00mm. This is how the 500mm was “justified”. I did get a nice shot of an eagle with the 500, but it’s a bit too heavy for me to even think about hand-held anymore.
I got a nicely-framed, full-frame shot of a resting butterfly with the 210mm.
or, expressed another way:
20mm - landscape
50mm - this is usually explained as “matching the angle of view of the average person”. Think point-and-shoot. This is the focal length most use.
Yep, just checked - the lens on the Argus C-3 is a 50mm.
85mm - 1 vote for portrait, one for table-top. I have one because it was the fastest lens (1.4) that Minolta made in the 50-100 range, and I wanted a shot of the aye-ayes (go find a pic - it will be worth the search). While they would come within 15 feet, the display is nocturnal, and I wasn’t going to use ISO 3200…
100mm - minimum for citters
130-150mm portrait
200mm - g/a grounded; critters in pens; general telephoto.
500mm - sporting events, wild critters
Or expressed another way:
Minimum kit; assumes you find zoom lenses acceptable:
28-80 (approx) great for walk-around
70-200 (approx.) when you need a longer lens. The 200mm is about as long as most people will need.
Not suprisingly, these are the first 2 real lenses I bought - I had a cheap Sigma originally because I didn’t want to sink the $ in glass if I was going to lose interest in photography.
The next 2 acquired
20mm prime. The 28mm on the zoom was just not wide enough, and the 28-85mm Maxxum lens is not that great ayway.
50mm Macro. Search ebay photo/lenses for “macro” in the title. They just are not cheap, even used. That’s because, once you point a macro at a flower, you want to keep the macro. Then comes the ring flash…
