Its amazing that people just don't grasp this issue. I was sitting with someone who was extolling the virtues of his micro 4/3rds system and telling me that his 300mm lens was much smaller and lighter than the 300mm lens on my full frame DSLR . It must be down to the marketing guys giving a false impression of what "effective field of view " means .

I didn't bother to try to explain and left the guy happy in his innocence.

A 300mm lens is just that, its focal length is not affected by the camera .

Hi

In clearing out some of my Parents older items, I came across a Canon EOS 40D, along with a 28-135 macro lens and a 70-300 IS lens. My guess is that these are at least 10 years old, maybe older, but appear to be in very good shape, and I would guess have been stored since at least 2008.

Are these worth even trying to sell, or possibly give to a friend getting into photography and wanting some equipment just to start with, or are they so old that the setup would just be frustrating?

Quick look online shows it was a good model a decade ago at 10MP, but not sure if it is worth bothering with at all now.

thanks in advance

Before I retired, my life centered around my work as a mechanical system designer and system forensic troubleshooter. When I retired last January, the cold grey winter weather in the midwest and the lack of feeling productive weighted on me heavily through the first few months thinking that perhaps retirement was not meant for me. Then came spring and I took the camera outdoors and I never stopped shooting since. Macro photography has become my passion along with learning about the insects, their life cycles, and their habitat.

Macro photography has become something that I can now do outdoors and indoors year round. My gear is centered around macro photography and the light modifiers I use are homemade and experimenting is a large part of the pleasure I get from it all.
