I want to buy a gift for the beginning bird photographer. She currently uses and has experience with 70 - 250 mm lens (the camera accepts Canon EF S). She says the birds just fly away as she approaches, or otherwise appear too small in the pictures - not enough zoom.
For my somewhat $1000 budget, I found the two lenses I could afford.
- One of them zooms over various distances, with maximum of 600 mm, but the opening drops to 6.3 at the far end. I can buy it new.
- Another that contra-intuitively used to be much more expensive, offers F 4.5 at 500 mm. I would need to buy it used on E bay.
The old lens is no longer in production, but I found many old 2012-like year reviews where it is claimed to be "legendary", even if it has no optical stabilizer. The similar new version with OS is absolutely not affordable. It looks to me more interesting.
How good is the idea to buy that old lens? I think it could give better images over far distance, or in low light, and also very different experience from the 70 - 250 mm zoom we already have.
