Sony FE 40mm F2.5 G Full-Frame Ultra-Compact G Lens

I recently purchased the Sony FE 40mm F2.5 G lens and it has exceeded all my expectations. Its ultra-compact design, weighing just 173g, makes it incredibly convenient for both professional and recreational photography. The high-quality G Lens optical design with three aspherical elements ensures impeccable sharpness and corner-to-corner resolution, a true testament to Sony's craftsmanship.The F2.5 aperture is perfect for low-light conditions, providing excellent light gathering capabilities. The depth of field is shallow and artistic, with the 7-blade circular aperture contributing to a beautifully natural bokeh. This feature makes it an ideal lens for portrait photography.Image quality is astounding. The aspherical elements counter various aberrations, maintaining high-resolution performance even at wide apertures. The defocused light sources are perfectly round, adding an aesthetic quality to my shots.The autofocus, powered by two linear motors, is fast and precise, a crucial factor when tracking moving subjects. The Linear Response MF is particularly impressive, providing immediate and precise control, essential for both stills and video.Overall, the Sony FE 40mm F2.5 G lens is a stellar combination of portability, performance, and quality. It's a versatile lens that has become an indispensable part of my photography kit. Highly recommended for those who value quality and versatility in a compact form.

Great images quality and compact size. Images have a snap that even some larger, pricier options don’t have. The 40mm focal length is actually far more useful for travel than the classic 50mm “normal” lens. With the high resolution Sonys, you can crop to your heart’s content. if you want that slightly wider view. My A7CR wears this lens most of the time.

Pricey, but it is a perfect compliment to a compact camera

Nice lens and the 40mm gives a lot of flexibility for everyday use. Built quality is good too, but not as sharp as a G-Master lens. For the intended use and price, it's a good choice.

I really wanted this lens, mainly because I went with mirrorless for size, among other things. And this pairs so nicely with my a7c. I’ve owned a Samyang 35mm f2.8 for a few months now. It’s small and compact, but probably a tad too small and for some reason I can’t quite explain, I haven’t really loved the pictures. Maybe just not as much as I had hoped. So I decided to upgrade and naturally spend 3 times the money for something .23 times better. Let’s be honest for just a sec. isn’t that what photography is usually all about? Oh well. I just took it out the box, slapped it on my a7c and it looks beautiful. Yes the hood is a bit awkward but that’s expected, they wanted it to be compact so I’m ok with it. The aperture ring is solid. It’s not gonna move around accidentally. I was quite worried about that. It feels a lot like my 20mm f1.8 but half the size. And it’s not as small as I was imagining, but it’s still great. Prob the perfect size. I’ve taken just a few pictures so far and it’s stunning. I can def notice the difference from my samyang. Auto focus is superb. Man I love Sony mirrorless.I struggled for a month decided if I should move forward with this lens. I really wanted a 35mm (trying to sell my Samyang right now). But I do also own a 28mmf2 so I think between that lens and this one (40mm) I’m good.Im not a pro. Just a major hobby I’ve invested way too much money in. So take it with a grain a salt but I felt there should be a review on Amazon just in case you can’t find any of the 16 reviews online or 16 YouTube reviews on this lens.Overall it’s tough to justify if you have a 35mm you love. Like a sigma f2 (ugh. I ended up picking this one over that one and I hope I don’t regret it) or the Sony 1.8 or 1.4. I guess if you really want something slightly more compact than those. Or if you just don’t own a 35mm maybe this one is a good alternative for you. (Again if you truly like the idea of a solid compact lens).For reference I’m able to fit it with my camera in my 5L peak design bag along with my 28mmF2 and my tamron 70-180. I always appreciate people providing that type of info so I hope someone else can appreciate this. I’d also easily be able to include my 55mm zeiss and 20mm f1.8 if I remove the tamron. Just FYI. It’s quite convenient to have a compact package. Not saying all my packages are compact. But not denying it either.

The lens as a compact, full-frame “Perfect Normal” lens that is sharp and well-made. It’s moderately priced and performs very well, with the ability to focus much closer than other 40mm lenses

Honestly the BEST lens I own. Gives you that wide angle without being GoPro wide angle, tons of bokeh, and just makes shots pretty. Sold build, wish it was smaller, she’s not little little but she will travel with me.

I bought second hand from Amazon warehouse, and expected some scratches on the body. It came without the original packaging, but the condition is like new. No sign of usage. Lens quality is great. Sharp, focuses fast, silent, great build quality.
