20mm f2.8 FE, 20mm f/2.8 e-Mount Full Frame AF Lens for Sony e Mount, Prime Wide Angle Lens for Sony e Mount a7cr a7cii a7c a6700 zv-e100 a6600 a6400 a7iv a7iii

Very pleased with the sharpness. Small, good autofocus, seemingly well constructed, fast (big aperture). The clarity this lens is capable is excellent, all the way to the corners. Pretty unbeatable for the price.

I couldn't be happier with this lens. I'm using it in a dedicated setup on a streaming camera (Sony A6400), with a teleprompter, and the lens is performing flawlessly. The image is clear and focus is quick, colors render very realistically, the front of the lens doesn't move when focus changes, so it works perfectly with the teleprompter, and vignetting is a non-issue. Don't hesitate to buy this lens. The price/value/performance ratio is excellent.

The lens out of the box feels high quality, much more than the standard Sony EF lenses, not the G or GM. The lens has a nice “heavy” metal body and smooth focal ring that feels great. The packaging surprisingly was great. The lens itself creates quite stunning pictures for its price. The clarity of it is better than expected and performs well. Has a usbc input for updating the firmware/software as your camera updates. Over all so far the lens was a great purchase. The AF on my Sony A7iv works flawlessly out of the box and is fast focus speed. Overall a good buy for a intro level good lens for your professional camera.

Impressive in every way. VILTROX has been on a tear lately introducing several extremely good, and also very reasonably priced, lenses, usually for Sony E mount, but increasingly offering lenses for Nikon Z mount and other as well. This VILTROX 13mm f/1.4 has just phenomenal sharpness edge to edge and corner to corner. Whatever design and manufacturing secret sauce VILTROX has developed seems to have mostly tamed the types of shortcoming -- like fringing, soft corners and distortion -- that have always seemed to plague super wide lenses, especially affordable ones. This lens is super sharp all the way to the corners, even wide open. At maybe the extreme edges you may see some slight decline in quality but it doesn't matter for practical purposes. Totally perfect? What is? Stunningly good for the price? Absolutely! Build quality seems very good. The lens is somewhat heavy due not only its size but also to the metal mount and barrel components. But it is really impressive as a super wide and fast optic. I have also recently purchased VILTROX 9mm, 40mm and 85mm lenses and they have all had fantastic resolution at a budget price. This ones a keeper here.

Overall the body of the lens is lightweight as it is an almost complete plastic build, the only mental on the lens is the lens mount (which is the most important part). The lens hood is not the best but it does the job. The lens cap is very secure and have not had it fall off in my bag. The focus ring does feel a bit gritty, almost as if it is rubbing on the plastic beneath it. As for the image quality is falls right in line with the Sony 40mm f2.5. Center sharpness is great. Now there is some color fringing but you really need to zoom on to see it. There is a drastic price difference between the Sony and the Viltrox 40mm f2.5, and for the price you cannot beat the Viltrox. The autofocus performs well even in low light. It is able to switch distances quickly with very minimal focus hunting. I believe the Viltrox can do 85% of what the sony can, even though the build quality is not close.

Viltrox has come a long way with their "upscale/pro/lab" lenses. I bought this primarily for astrophotography (Milky Way) and landscapes, and have been pleasantly surprised and satisfied. Excellent feel and a quality build. Excellent results. Easy updates through a USB port on the lens. Unbeatable, especially considering the price! 99% of a Sony prime but a fraction of the cost.

This is a wonderful lens and an incredible value for money. I say this as an amateur photographer for fifty plus years with over 75 lenses and experience with many more. I use this lens on a Sony a7II. It is very sharp and has great color and contrast. For me 40mm is the most versatile focal length, and I have several, including the Voigtlander Ultron 40mm f2, the Konica 40mm f1.8, and the Carl Zeiss Jena 40mm f4.5. This Viltrox AF 40 is a great addition to the collection.

Update: After using this lens during low light and sunny day, I am going to lower my rating from 4 to 3 star. The Likes and Don't's remain unchanged, but the Don't's is getting more noticeable and getting in the way of the operation, and getting a bit annoying. I still like the quality of the pics, and if this lens would have been made to the specifications of the Pro Series, it would have made 5 stars, and I would gladly pay more for it. What I like: Good quality images in low light. Full metal body. Light weight. What I don't like: Lack of a "click" option for the aperture ring and it's too smooth for my liking. I just left it in the Auto locked position and use the camera to control the aperture. The manual focus ring is too prominent, making it impossible to avoid touching and thereby moving it. I mounted this lens on my Sony A6400 which I use for traveling. Overall, I like this lens but the design could be improved. At this price, it's a very good lens for serious amature.

Permet de se balader avec son APN dans une configuration très compacte. Les images sont très correctes. Il faut bien avoir en tête qu'on ne peut pas jouer sur l'ouverture ! Mais est-ce vraiment un problème à cette focale ?... Pas cher !

Ho comprato questa lente con aspettative normali, ma alla prova dei fatti si è rivelata un acquisto decisamente positivo. La uso con la mia Sony A6400 e la resa cromatica e la nitidezza che si riescono ad ottenere, soprattutto chiudendo il diaframma, sono decisamente notevoli, considerando il prezzo di acquisto. Ormai è la mia lente di riferimento, leggera e performante, sempre montata sulla A6400 che già pesa davvero poco. Consigliata per budget limitati, tanta resa e poca spesa...poi, se avete soldi da investire in ottiche più blasonate, probabilmente la qualità, anche costruttiva, sarà migliore.

parfait.

ソニーEマウントのフルサイズ対応レンズです。 純正品には選択肢が少ないパンケーキですが、この製品は小型で軽量、そして安価。 ボディキャップ代わりにつけっぱなしにしてもいいですし、日常使いにおいてもカバンの中にポンと放り込んで邪魔にならないサイズ感。 散歩するときに持ち出すメインの1本に加えて、思い立ったらすぐに使える28mmがあると思うと心強い。 このサイズ・価格でAF使えるのがとてもありがたい。 レンズフードは装着できず、F4.5で固定となりますが、1万円台で小型軽量でAF対応してて他に何を求めますか。

Pour son prix, le Viltrox 40mm peut convenir à ceux qui font des photos statiques, mais dès qu’on le pousse un peu, ses limites deviennent évidentes. ✅ Les points positifs : • Prix abordable • Construction solide en métal • Compact et léger • Piqué correct au centre (mais pas exceptionnel) • Vignettage modéré, facilement corrigeable en post-prod • Rendu des couleurs légèrement contrasté, ce qui peut plaire selon le style recherché ❌ Les points négatifs : • Autofocus lent et hésitant, surtout en mouvement • Déformation très marquée dès qu’on bouge un peu • Piqué décevant, surtout sur les bords de l’image • Bokeh un peu nerveux, pas des plus agréables Si tu cherches un objectif pas cher pour des plans fixes, il peut faire l’affaire. Mais pour de la photo dynamique ou de la vidéo, il est clairement en retrait face à des alternatives comme le Sony 40mm f/2.5 G.
