There has been a lot of talk/chatter/discussion/mentions of concern about the future and/or state of the line-up of APS-C E-mount lenses coming from Sony lately (and the lack of any such since late 2013). So I decided to do a little bit of research into what's out there and compare to several of the other systems. Additionally, some have noted that as Sony is one of only a few companies supporting both cropped and "full-frame" formats in their mass-market lens lineups, a comparison to what Nikon and Canon offer in their APS-C lines is perhaps the most indicative of the state of the market and what perhaps to expect from Sony going forward. I agree with this thought and believe that Sony has shown that it's goals are directed at competing with Canon and Nikon at the top of the interchangeable-lens camera market rather than compete against the other cropped-only lines of otherwise great brands like Fuji, Olympus, Panasonic, and Samsung (assuming Samsung stays in the ILC market much longer). While Pentax just (re)joined the cropped+full-frame club, I think it is fair to say that Pentax is not seeing the same level of market- and mind- share that Sony, Canon and Nikon do. Perhaps that will change, but for now, I think is fair to count Sony, Canon, and Nikon as the major multi-format ILC players (where ILC means either DSLR or mirrorless). I've also chosen to focus only on 1st Party offerings and not those from third parties like Zeiss, Sigma, Tamron, and the Rokinon/Samyang group, mostly in order to simplify matters and because the 1st party camera/lens makers cannot really be held accountable for the offerings by third parties. I am including the Sony-Zeiss lenses like the SEL24F18Z, as those are primarily Sony-branded and manufactured. That leaves out some great offerings, I know, but I'm trying to compare apples to apples here - bear with me. In order to do a comparison, I needed to find a good source of a list of actively produced and sold lenses for each manufacturer. And for that I have turned to B&H, as the largest camera specialty seller in North America (my apologies to my friends and fellow forum members in Europe, Africa, Australia/Oceana, Asia and South America). I think this is a relatively fair choice of a source as B&H is (a) a major dealer of all brands and sells essentially every lens model in production, and (b) this forum benefits from links to B&H So without further ado, I will provide four links to page listings of actively available APS-C lenses as of today (February 25, 2016): First, our own format, Sony's APS-C E-mount lineup (17 lenses, some duplication by color): Mirrorless System Lenses | B&H Photo Video Next, Sony's own A-mount APS-C lenses for its DSLR/T models (12 lenses, no duplication): SLR Lenses, DSLR Lenses | B&H Photo Video Third, Nikon's F-mount AF-S APS-C lenses (21 lenses, 1 bundle, not much duplication, but significant focal length overlap): SLR Lenses, DSLR Lenses | B&H Photo Video And finally, Canon's EF-S line of APS-C lenses (20 lenses, multiple duplicates - especially of 55-250): SLR Lenses, DSLR Lenses | B&H Photo Video Now, some thoughts on the lenses and how the line-ups compare. First, in general Sony's E-mount line-up actually stacks up fairly well against each of the other APS-C line-ups from Sony's own A-mount, Canon, and Nikon - our other dual-format players. There are clearly some areas that Sony is lacking coverage on, particularly long or fast zooms and macros, but Sony APS-C E-mount actually seems to have a broader line-up of primes. Second observation, Canon and Nikon both seem to focus mostly on zooms for their APS-C DSLRs. Canon appears to offer only 2 primes - a pancake 24/2.8 and a 60/2.8 Macro. Nikon offers a 10.5/2.8 Fisheye , 35/1.8, 40/2.8, and an 85/3.5. In A-mount, Sony offers a 30/2.8 Macro, 35/1.8, and a 50/1.8. Our E-mount system includes a 16/2.8, 20/2.8, 24/1.8, 30/3.5 Macro, 35/1.8 and 50/1.8. Not bad Sony (but maybe a longer macro, like a 50/3.5, would be nice to see; and that Nikon 85/2.8 is interesting). What I think both these observations suggest is that Sony, like Canon and Nikon, has attempted to provide coverage of most of the commonly-desired APS-C focal lengths in both primes and zooms, and then will fill in with full-frame lenses going forward, especially in the longer and faster primes and the long "action-oriented" zooms (like the 70-200s). I will try to update this with further observations and comparisons, but that's a good start. I will end now with one personal observation. When looking particularly at Sony's own A-mount APS-C line-up, it looks like most of the lenses offered have comparable counterparts in E-mount. Just three exceptions stand out as not having E-mount versions: the 16-50/2.8 constant aperture zoom, the 18-135/3.5-5.6 zoom, and the 55-300/4.5-5.6 telephoto zoom. If Sony is listening and is interested in making any of those three, I could be made to part with money for one or more.
