Panasonic Lumix S5 IIX: Ideal for hybrid shooters, DSLR, and system switchers
you've been shooting on an APS-C or DSLR camera before, the Panasonic Lumix S5 IIX is a fantastic upgrade. It's notably smaller and lighter than many DSLRs. So while the handling might feel a bit different at first, you'll quickly appreciate the more compact, less bulky design. There are not as many native lenses for the S5 IIX available as it is the case within the Sony and Nikon lineup, but there are third-party options like Sigma available. And if you want to keep using your older glass, Canon EF to L-mount adapters, for example, are available.
Sony A7 IV: Best for DSLR and system switchers, as well as content creators
Switching to Sony means unlocking incredible mirrorless flexibility. The Sony E-mount system is the most mature on the market, with an extensive range of native lenses and strong third-party support from trusted brands like Tamron and Sigma. The A7 IV shines with its real-time Eye AF, detection, and tracking options – features that make focusing faster and more accurate than many DSLR systems. So, if you're coming from a DSLR, this camera feels like a serious step up in autofocus and creative control.
Nikon Z5: Budget-conscious DSLR option, best for stills-focused shooters
If you are on a budget, the Nikon Z5 offers one of the most affordable ways into full-frame mirrorless with great image quality. The body design will feel very familiar if you're upgrading from a Nikon DSLR, and thanks to the FTX adapter, you can continue using your trusted F-mount lenses seamlessly. The only downside is that the Z5 doesn't have IBIS, which is usual at this price point. That means handheld shooting with longer lenses or video might require a steady hand or a tripod.
And if the bundled lens doesn't suit your photography style, there are plenty of alternative lens bundles available on Wex – many of which offer great savings too.

Personally, I would lean toward the Sony A7 IV. Its autofocus performance is unmatched, as well as its lens options. The flexibility makes it a standout choice, especially if you're open to switching systems entirely. That said, if you want to stick with your current brand and already own a lot of DSLR lenses, staying within the same ecosystem is a smart and budget-friendly way to jump into mirrorless photography.
