Newbie with some inherited equipment...

[SteveS Cup]

Hi all,

Long story short, my gf wants to get in to photography as her grandad was a fatastic photographer (traditional film and moved on to DSLR's later, we have some incredible photos of various scenes / close ups).

He unfortunately passed away over 2 years ago and my gf now has a few bits of his newer equipment. I'm sure there's more mixed in with the older stuff at her parents house but we currently have here the following...

Canon EOS350D camera (I don't think this was a particularly expensive camera as I know his preference was the old style film camera)
Canon Ultrasonic EF 75-300 lens
Tamron SP AF 90mm lens

Would someone be kind enough to explain the whys, what's and when's!?

For a beginner, are these lenses any good? I know he was in to taking very close shots of nature, so would these lenses be any good for landscapes / architecture?

Is there some sort of auto setting that would help to begin with?

I'd really appreciate any help!

Thank you very much!

She is using this to see if it's worth investing some money in to it as she has her eye on a Nikon.

So I doubt she wants to buy any lenses for this canon (unless it would fit the Nikon as well?) or was quite cheap.
