...unless it's a Nikon DX labeled lens, then the crop factor is already figured in, so a 50mm DX is a 50mm lens, not a 75mm.

Umm, that is incorrect, no lenses for DSLRs factor in the camera crop into their focal lengths.

For portraits I'd go with something longer than 50mm. 85 or 135 mm come to mind.

BTW, enjoy your new lens.

A very popular prime lens is the 35mm f1.8 that will auto focus on the D5000. That lens runs about 200, which is more expensive than the 50mm, but at least it autofocuses. The perspective is a little different, but it's definitely a worthwhile lens.

Also, like Argote said, you will always need to account for the crop factor no matter what kind of lens, DX or not. So a 50mm DX lens is 75mm, and not 50mm.

i got the this 50mm the other week for ?70 boxed (2nd hand)... before this i had the 35mm f/2. i needed some money though so sold the 35mm for ?200. first thing i thought though was that the 50mm isn't as sharp as the 35mm, but still a very nice lens.

all in all i'm happy with the small downgrade.

Stupid, if true. Can't see why they can't make a 50mm lens that's a 50mm lens. And no site out there seems to say definitively in either direction. Although the only 'proof' I have myself is owning both a 50mm DX an a non-DX 50mm and they don't produce the same image. The non-DX 50 mm is definitely a closer shot. So since almost every site out there conflicts information about DX lenses, all I can go with is my personal experience on the two lenses I have.

Ah well, as long as a lens does what you want it to, it's the right lens for the job.

That would be because it actually is a 50mm lens on a full frame camera, everything is measured in full frame units, otherwise it'd be a confusing cluster****.

LOL the thing is, they are all 50mm lenses... so really you should be complaining about how they can't make a camera body that sees 50mm as 50mm... because focal length is focal length it's just how your camera perceives it as being :p (I think).

This only applies to everything that is smaller than or equal to 135 film. Medium and large formats are in their own league. (please correct me if I am wrong)

What Argote already said. On full frame camera bodies 50mm IS 50mm.

You are correct as far as I know, as you said, modular cameras are a league of their own

I would rather have recommended the Nikon 35mm f2. It's a much sharper lens, even with the lens wide-open. Also, it's not a DX, which means you can use it on a FX camera too. I use it on a D300, which gives me almost a perfect 50mm.

    • IBM reveals sub-1nm chip technology, production expected in another 5 years

      By pradeepviswav · Posted

      IBM reveals sub-1nm chip technology, production expected in another 5 years by Pradeep Viswanathan TSMC is now leading the chip manufacturing industry with its 2nm-class process node called N2. Samsung Foundry also has a 2nm-class process node called SF2. TSMC says N2 entered volume production in Q4 2025. Samsung says SF2 started mass production in 2025. Today, IBM announced the world’s first sub-1-nanometer chip technology, marking another major semiconductor research milestone. The new technology is based on a 0.7nm, or 7-angstrom, node and uses a new transistor architecture called “nanostack.” The new design vertically stacks and staggers nanosheet-based transistors so that more components can fit into the same chip area while also improving performance and power efficiency. IBM claims that this new sub-1nm chip can pack nearly 100 billion transistors onto a chip the size of a fingernail. This offers almost twice the density, up to 50 percent higher performance, or 70 percent better energy efficiency when compared to IBM's 2nm node design announced back in 2021. Also, IBM mentioned that this new architecture can deliver 40 percent SRAM scaling. It is important to consider that this announcement from IBM is a research milestone rather than a near-term process node launch. Back in 2021, IBM unveiled the world’s first 2nm chip design, claiming 50 billion transistors on a fingernail-sized chip and major performance and efficiency gains. Five years later, IBM’s 2nm technology has still not entered mainstream commercial production. That is because IBM is no longer a major commercial chip manufacturer. It sold its chip manufacturing business to GlobalFoundries years ago and has since then focused only on semiconductor research, IP development, and partnerships. To productize its 2-nm chip technology, IBM partnered with Japan’s Rapidus, but it has not resulted in anything shipping at scale. IBM says that its new sub-1nm technology can reach production as early as within the next five years. If that happens, it will likely depend on manufacturing partners, advanced EUV tooling, and years of yield improvements.

      It's funny when thieves accuse other thieves of stealing. Ai companies just blatantly siphoned all the knowledge of the internet without consent and are now selling it with their service... so excuse me if I find this a bit ironic.
