Canon Lens Questions

I have a few questions and just wondering if anyone can help

Does anyone know if the kit lens from the 300d will fit the 400d?

Or would I be better off just getting the 400d with the kit lens?

Is this a good/okay lens Sigma 28-300mm f3.5-6.3 DG Macro Lens?

Or would I be better off getting a 75-300mm(or similar) and a 28-90mm(or similar)?

These are the three I am looking at just now, Good? Bad? Simga/Tamron alternative better?
Canon EF 28-90mm f4-5.6 III Lens
Canon EF 75-300mm f4-5.6 III Lens
Canon EF 75-300mm f4-5.6 USM III Lens

Also wanting to get the Canon EF 50mm f1.8 II

Or if anyone else wants to suggest some lenses then I have about £300 to £400 to spend on lenses (would rather keep it closer to £300)

Thanks

As far as I know, the 300d kit lens will fit the 400d

Even if it didn't I would suggest not getting the kit lens but a different/better lens (I'm not keen on the Canon kit lens tbh).

I'm not sure about the other lens, tbh, although lower F numbers usually means better quality

I'd say it all depends what you wanna shoot Megan, there are some wildly varying focal lengths there!!

Sigma and Tamaron are good alternatives, they are 80-90% the quality of the lenses made by the camera manufacturer's for generally around half the price. There is the odd problem with Sigma lenses, but if you get a good un you get a good un!

Apparently Sigma keep a stock of the good uns at the factory for the ones that they have to replace on quality grounds.

Have you thought about swapping over to Nikon . No problem with what lens fits what camera

Yes it will fit fine.

Getting a lens when you buy a camera is a good way of getting a lens for less though.

Remember there's 2 types of lens for EOS Canon's.

EF lenses will fit cropped sensor EOS models like the 300/400 as well as the full frame models.

EF-S lenses will only fit the cropped sensor EOS models like the 300/400.

The 50mm f1.8 (nifty fifty) is a great little lens and great value.

I'd also suggest the 17-85mm (in my sig below) as good image stabilized lens that has a good focal range for everyday shooting. It's a step up from the kit lenses and is often what people choose with Canon 40D and 50D models.
