Will old 35mm lenses fit new DSLR cameras?

I'm sure this is a question that has been asked many many times, but I didn't see my specific camera/lenses and wanted to get some opinions.

I have an old 35 mm Minolta Maxxum 5000i with 2 lenses

Sigma DL zoom 35-80mm

Sigma 70-300mm

I'm still a camera novice but want to get a decent entry-level camera (Nikon?). I would like to know if these lenses would be compatible/be able to use them with a DSLR camera. Are there certain brands that are compatible and others that aren't? What options do I have if they aren't?

I understand that ideally I would like to get new lenses, but since I have these already, I would like to know their compatibility.

Also, if you have any recommendations for an entry level $500 - 600 camera, please let me know. My brain hurts from looking at all the options. If there's been a recent upgrade, and the older model is still a great option and maybe even a little cheaper, that would be great.

Thanks for any suggestions. Any help is appreciated.

You can use your old Minolta lenses with any Minolta or Sony (3-digit model) dSLR. They will not fit any other brand. When you buy a dSLR though, get one with the kit lens. First, the lens is very cheap when bought as a kit and second, your old lenses won't give you wide angle. You will notice a crop factor of 1.5X so the normal/standard focal length of 50mm before would now be at 35mm.

To add, if you also want doing video, you can also consider the Sony SLT (two-digit) models. Beware, Sony 4-digit models are mirrorless and the lenses they use are different.

The Minolta Maxxum lenses may fit a Sony Alpha mount camera. They will not fit a Nikon. The Nikon F is one of the narrowest among the digital SLR's. There's no adapter to fit the Minolta or Sony lenses to a Nikon body.

Without any adapters:
Nikon MF or AF lenses fit most (not all) DSLRs.
Canon changed their lens mount when they went AF in the 80s, so none of their MF lenses will fit without an adapter.
All Canon AF EF lenses will fit any body that they've ever made. All EF-S lenses are only usable on APS-C cameras.
Minolta/Sony - The mount is the same. All AF lenses can be used with any body. None of the old MF Minolta MD lenses will work without an adapter.
Pentax - All lenses work on all bodies without an adapter.

WITH AN ADAPTER:
You can put Nikon lenses onto Canon bodies, but not the other way around.
Sony's A7 series can accept just about any lens ever made with an adapter.

You can get adapter mounts, but you will not have any form of comm or connection between the lens and the body.

Try Novaflex for adapters.

The Sony a58, a77 II (crop sensor cameras) and a99 (full frame camera) all use the Minolta Maxxum "A" mount just like your old Minolta Maxxum 5000i. Your lenses are fully compatible with those bodies. On the a58 or a77 II there's a 1.5x crop factor so your 35-80mm zoom will have the equivalent angle of view of a 52.5-120mm zoom and your 70-300mm zoom will have the equivalent angle of view of a 105-450mm zoom. On the full frame a99 they will be the same as on your 5000i.

The Sony a3000, a5000, a5100 and a6000 mirror-less crop sensor cameras all use the newer Sony "E" lens mount. The Sony LA-EA3 allows use of your "A" mount lenses on these bodies.

The Sony a7, A7R and a7S are mirror-less full frame cameras that use the "E" lens mount as well. The Sony LA-EA4 allows use of your "A" mount lenses on these cameras.

Frank seems ti imply that all lenses (including Minolta) will work on Pentax without adapter.

Let it be made plain. Sony took over Minolta about 8 years ago, and most Minolta lenses (or Sigma etc made for Minolta) can be used on Sony DSLRs, with some restrictions in practicality. If Minolta lenses can be fitted to any other brand (Nikon, etc) using an adapter then there will be severe restrictions in practicality and/or image quality - in general it is a no no.

Let us now hope that someone who is very familiar will Minolta lenses of all dates, and all the latest Sony DSLRs, sees this question and can give good advice. My instinct would be to go into a good photo retailer with your lenses and actually see what they do on Sony bodies. Then you will be absolutely sure that everything works as you want it to.

I wouldn't recommend it.

Although it may work, you won't be satisfied with the result, unless what you have are old but high quality lenses. Digital cameras are far more demanding than film cameras. In the film era, it was rare for anyone to go beyond 8x10 enlargement. Most images were printed to 3.5x5 or 4x6, and occasionally 5x7. So flaws and lack of sharpness tended to show very little. Today, it isn't unusual for someone to crop heavily or zoom into 100% magnification and look at it at a pixel level. You will find, older lenses are quite lacking.

Also, older zoom lenses were not great in terms of performance anyway. That's why people prized having prime lenses. (non zooms) Today, even less expensive "kit" lenses are pretty good. I would strongly recommend getting a new lenses, and maybe use those old lenses to experiment around.

To my knowledge the only lenses that fit current Pentax DSLR cameras are lenses from Pentax SLR film cameras. This fact has made even used Pentax lenses on the scarce side. Your best bet is probably sell your old Minolta and move into a decent DSLR. There's such a thing as being cheap and there's such a thing as being cheap! If you can't afford a DSLR then go for a great "bridge" which has one zoom do it all lens that goes from wide angle to a telephoto you could not afford with out putting a second mortgage on your home. Add to that this lens will be capable of macro work also. I added a Pentax "bridge" camera as my "second camera to my DSLR, which I made a 16x20 print which floored me as it is sharp as a tack.
This big push towards owning a DSLR is fine. But EVERYBODY wants the cheapest one they can find. Then what are you guys going to do when it comes to adding, a 50-200mm lens for telephoto work, or a macro lens for close-ups of flowers and other small objects?

Yes it will 100% used it you just got to jam it on pretty hard and it stays try using a lot of force

Yes they will you may need a t mount remember older lenses on a digital slr will magnify 1.5x compared to the old lenses. Thats great for telephoto not so great for wide angle.
