FT to MFT?

I accidentally ordered a four thirds mount Olympus 40-150 f4-5.6, I don't have an adapter, and I wanted to use it on my new g7. Should I just return it, or is there some advantage to using the bigger lens? I do want to get the Panasonic 45-150 eventually, but this was my attempt to get a zoom on the cheap. I have some Nikon lenses, a 55-200 particularly, but it is very big on the g7 and the g compatable adapter itself is heavy. So, any advice will be appreciated. I'm freaking poor, this is probably not the best hobby considering my budget, but anyway, Thanks in advance.

My thought would be to return it. I believe that you would be much more pleased with the Oly MFT version of the lens (sometimes called the plastic fantastic) which can often be found at a quite low price.

Ah, well darn. Ok, I'll return it once it arrives. Incidentally, would anyone have suggestions on really low budget lens options for the G7? I think I will go with the Panasonic 45-150 since it has OIS. Like I said, I have the Nikon g adapter, using if with a 50mm 1.8 mostly though. I have a Fujian 35mm 1.7 cctv lens coming in the mail at some point, so I will have a c mount adapter FWIW. But most of my photos are of insects and spiders actually. I have a Raynox dcr-250 and some various other diopters, and mft macro tubes. The kit lens actually does an admirable job, all things considered, with the Raynox and a 10 diopter. I want to get much more magnification, but using my Nikon lenses with the Raynox just is unwieldy, and I'm afraid I'll damage something. Here's an example from today.

It seems Olympus sells that lens for $99 once or twice a year.  That's what I paid for mine.

you can get a cheap electric adapter for 4/3 mounts, it is mediocre.

want dummy adapter, now you have even more mounts to choose from.

I see lots of 80-200 lenses out there really cheep.

Yes i got one at that price a few years back and then misplaced it . And i got another new one at 59$ once

I do mostly shoot handheld, so I do think I better look for a Panasonic on the cheap. For macro, I'm actually considering getting a Raynox msn-202 that is higher magnification than the 250. I am thinking that may actually work good with the kit lens, it doesn't have a huge zoom but I'm getting pretty close now, and I could remove a layer of glass, get closer, but because of the limited zoom range, I will probably still have decent dof for that diopter. I would then have time I think to get the zoom at my leisure. I have a 1000mm effective zoo on my Fuji, it isn't great in low light, but it has more range than I'll ever get with the g7 handheld, I can mostly stick to that for birding. The kit lens actually isn't terrible with a Cano 1.6x screw on teleconverter I have, that with the ezoom is ok for just running about. So, getting my macro rig as light as possible is most important. Any thoughts on the msn-202 idea?
