positive:Sharpness (especially wide open)
Neutral colour
Size and weight
Good close focus performance
AF performance
negative:Slow max aperture
comment:This is now my go-to lens for travel and street photography. The size and weight make it a great choice for situations where you want to capture natural moments or just don't want to attract too much attention.

The AF performance is outstanding - it's actually a tad faster than the 35mm f1.4 GM and is incredibly accurate. Sharpness is excellent in the centre wide open, with very good corners (improving to excellent around f2.8 on my copy). Colours are neutral, without feeling sterile.

It's huge upgrade from the Batis in terms of AF performance, but is also sharper, especially at the MFD. The GM just beats it in terms of sharpness across the frame wide open and has more pleasing rendering, which comes at the expense of size, weight and price. I found it sharper than the Sony 35mm f1.8 and Sigma 35mm f2, with more pleasing rendering than the Sony. It's fully weather-sealed, which is a big plus compared to the Sigma.

It's superficially similar to the 50mm f2.5 G, with similarly neutral colours, but is noticeably faster and more accurate on the AF front. I found my 40mm G sharper wide open, with the 50mm G having a slight edge in terms of rendering due to the longer focal length.

price paid:£430
positive:Very light, super sharp, great flare control and no distortion, fast AF, aperture ring.
negative:Price. Pity it's not F2 (but then it wouldn't be so small)
comment:I was fortunate to get this lens at a £200 discount from Sony by buying it with the camera (A7 IV) which makes the price fine. Full price in the UK of £630 may be a bit steep. The build quality is top notch and I have no idea why a previous review questions the build quality. It's all metal and weather sealed. It feels like a premium lens with it's metal construction and most on line reviews concur. It's very sharp and I can't get it to flare. No CA either. I really like the 40mm focal length. It matches what I see as I walk around. When buying the A7 IV I decided to forgo a standard range zoom and try primes for a lightweight kit and so far I am not missing the zoom.

price paid:$478 USD used
positive:Quick focusing
Low weight
Small size
Unobtrusive
Solid build
negative:Buttons and switches are crammed in.
comment:I enjoy the versatility of this lens. It is perfect for replacing my 35m and 50mm with a single lens. The images from my A7RIII look good to my eyes. This creates a great trio of the FE 20mm f/1.8 G, FE 40mm f/2.5 G and Sony FE 85mm f/1.8 as a flexible walkabout prime kit. While the buttons and switches are crammed in it is still impressive they exist on a lens this size.

comment:I made what I thought would be too low of an offer for this on Greentoe, but it was accepted. This lens has most of the tradeoffs typical of recent Sony budget lenses: very quiet, fast, reliable AF, decent sharpness/contrast, not the smoothest rendering, and questionable build quality. "Made in China"

It could be seen as a replacement for the old 35mm F2.8 ZA Sonnar that was recently reduced to the same $600 retail price. It is 50% larger and 44% heavier than that lens and adds several additional left-hand controls. This is also the same price as the mostly mechanical Pentax-FA 43 F1.9 Limited.

My previous favorite 40 mm lens is the inexpensive Canon EF STM pancake that has recently been discontinued (March 2021.) This lens has a noticeably less angle-of-view than the Canon, but it is slightly closer to the Canon than it is to the Pentax 43 (and Sigma 45). Maybe it is a 41 mm?

One of weaknesses of the ZA was close focusing. This lens focuses closer than the Canon with greater magnification, despite "MACRO" being written on the side of the Canon. The Sigma focuses even closer with even more magnification. The Sigma also has less focus breathing.

It has a similar amount of barrel distortion as the Pentax 43. The Canon 40 and Samyang 45 have less distortion. The Sigma has slightly more pincushion distortion. Sony forces the distortion correction making it impossible to compose shots using the optical barrel distortion. Sony, please enable this setting on your cameras for all lenses. It really makes no sense with this lens. It made me assume the lens was much worse.

The focus control sounds and feels worse than the ones on the 28-60 and 50 F1.8. The odd hood shape makes the focus control fall easily to the finger tips. The aperture control indents are better than those on the 20 G, but still don't match the precise feeling of those on the Sigma. The textured, thin rubber focus control on the Canon is nicer to use. The 1980's can have their MF switch back.

This lens has worse chromatic aberration control than the Sigma especially midfield, but it does have less CA than the Sony and Samyang 35mm F1.8 primes and the Samyang 45mm. It has well corrected spherical aberration. The background rendering a bit nicer than those F1.8 primes, but out-of-focus highlights have a lot of structure from the three aspherical elements. Generally the rendering is decent. It lacks the under corrected spherical aberration magic of the Sigma.

The stock hood is ugly but very functional. It is mostly plastic with a thin aluminum veneer on the outside. It uses a similar mount as the older 49mm filter lenses, but their hoods will not attach due to the overlap of the focus control over the hood bayonet. The shape of the hood makes it easy to adjust the focus control, unlike the Sigma's hood that interferes with the focus control. I prefer the little metal screw-in ES-52 hood for the Canon 40 STM. At least Sony avoided useless magnetic lens caps.

I was initially rather disappointed in this lens. It is cheaply made compared to the less expensive Sigma. It slots into a range with many nice affordable lenses. Sony may intend these high margin primes to go with reduced control camera bodies like the A7C. It is a poor bargain for photographers, but it may be marketable.

compared to:Sony Zeiss 2.8/35 mm ZA
Zeiss Batis 2.0/40 mm CF
price paid:695,00 €
positive:Small and lightweight, great look and feel of the build quality, short focusing distance,
weather sealing, aperture ring, focus hold button, AF/MF switch, internal focus design
negative:No OSS, therefore only a "4" in the build rating
comment:Sharp, extremely sharp from f/4. I can't see any difference at f/5.6 compared to the 40 mm Batis. However, the 40 mm Sony is much smaller and lighter. The sharpness comparison with the 35 mm Sony-Zeiss is clearly in favour of the 40 mm Sony. Despite the small form factor, the new 40 has all the controls you could wish for.
For me, the ideal lens for inconspicuous street photography. Highly recommended!
