FF Nikon Z cameras automatically crop the image once DX lens is attached. There is a hack not to do that but you have to slightly detach lens. Not recommended.
I haven’t tested the 40 f2. But the only thing that one may miss is the MP. Focal length between 27 mm on full frame and 40 mm native Z lens in full frame is the same.
Even though 40/2 is a very average lens, I bet it will give you a better final resolution. The 1.5x crop is pretty hard to overcome even with an ideal lens.
Wir haben lange auf eine Vollformat / FX Retro Kamera gewartet. Endlich ist eine da. Und jetzt soll es eine gute Idee sein an dieser Kamera mit APS-C Objektiven zu fotografieren? Selten so einen Blödsinn gehört.
Hello,, it's a great review. I am a beginner and I have a Nikon Zf (24.5 Megapixel), so does that mean if I use this lens then the megapixel will drop to 12.25 Megapixel? Also I understand that the 27mm will become 40mm equivalent. But how about the aperture? Will it still be 1.2 or it will become 1.8? I already have a “NIKKOR Z 40MM F/2 (SE)”, I am just wondering thinking would it be similar to this Nikkor F/2 lens? I want to get a large Aperture lens so I can get a better low light photo and video and also better bokeh. So if it’s similar to 40mm F/2. Then there is no point for me to buy this lens if the aperture will become 1.8 when I put it on my Nikon Zf. I am just a little confuse could you please advise if that’s okay with you. Many thanks!
Here is my short answer to your question relative to aperture. By placing a crop sensor lens on a full frame body you only change the field of view not the focal length of a lens. An 85 mm lens on a full frame camera is still an 85 mm lens on a crop sensor camera just with a field of view of 85x1.5= 127.5 mm A 27 mm f1.2 crop sensor lens on a full frame body has a 40.5 mm field of view but aperture is still f1.2. Aperture is a a measurement inside of a lens, it does not change based on what body you put it on. F.1.2 lens on a crop sensor camera is an F1.2 lens on a full frame camera. Exposure settings don’t change just the field of view.
17:21 'On a full-frame body this is going to become about a 40mm lens'. It's always a 28mm lens, and on a FF body it's a 28mm equivalent lens also, since the crop factor is 1. On a DX body it's equivalent to a 42mm f/1.8 lens - that is it performs the same as a 42mm f/1.8 lens would on a FF body in terms of angle of view, depth of field, diffraction blur and light energy (thus noise) projected on the sensor.
incorrect, because on FF body it will be automatically cropped to APS-C size just like on DX body. This lens can not cover the FF image circle, it's always 40/1.8 FF equivalent.
@@USGrant21st It will only be automatically cropped if you choose that option - you don't have to. Who knows how big is the exact image circle, many APS-C lenses will cover most or all of an FF frame, maybe with some vignetting in the corners. But in the end the point is that it is always a 27mm lens. The FL doesn't change however you crop it.
@@BobN54 what are you talking about? - there are no APS-C lenses that cover full frame. There is absolutely no reason to expect this lens covering anything more than APS-C, there is already vignetting visible. So yeah, it's going to be cropped one way or another. Saying that "FL doesn't change however you crop it" indicates you don't understand what the issue is. FL means nothing if you don't know lens coverage. We are not talking about physical FL or aperture, we are talking about "equivalent" FL and aperture, i.e. which FF lens would produce the same image.
@@USGrant21st What am I talking about? I'm talking about the truth. The actual facts. There are plenty of APS-C lenses that will cover a full frame. For instance, watch ruclips.net/video/8r89uPvbEUc/видео.htmlsi=gDndSimk5chYwZb1 I understand fully what the issue is. First, FL is what it is. If you say it 'changes' due to a crop, then you're abusing the concept and the language. Certainly the angle of view that a lens of a given focal length gives depends on the frame size. We tend to use FL as a proxy for AoV, but it only works if you know the frame size. But the point I was making is that there is no way that a 27mm lens fitted on a FF body 'becomes' a 40mm lens - that's just wrong. If it's cropped to APS-C it will provide the same AoV as would a 40mm lens using the full FF frame. If it's not cropped, and you use the extent of whatever image circle it gives ( which is likely to be bigger than the minimum 29mm needed for APS-C it will offer the same AoV as a lens using the full FF frame somewhere between 27mm and 40mm, depending on how large the image circle actually is.
I see no point using a crop lens on FF body, you lose so much doing that. This lens becomes pretty unremarkable 41mm f/1.8 FF equivalent with a huge loss of resolution. It's large and heavy and it's priced at $545. Makes zero sense buying it, one can get Nikkor 50/1.8 - a lot better lens, which is frequently on sale for $526.
@@TouchLifeStudio whatever impresses you must be subjective, because objectively there isn't anything. Nikkor 50/1.8 is objectively the best 50(55)/1.8 available in any system.
@@USGrant21st I hear your point. Nikon markets the Zf as a retro camera, and the 27 mm 1.2 is the closest one to that retro style. I own both lenses. Image quality are great on both but for those who value look and feel of a lens, the Viltrox lens for this right now Image quality wise, the 50mm 1.8 is fantastic and I love it too.

Thank you!
Viltrox is killing it!
💯 agreed!
Yep!
depends on definition of "it"
the best review about this lens. You have a good pragmatic approach, and I like how you build perspective when talking about a particular detail.

I appreciate that!
Beautiful images 💐💐
Many thanks
Very good review. I will buy it for my Zfc and my Zf. THX 👍
Good choice!
This looks nice but I’m waiting for the 135.
It appears that the longest focal length that Viltrox makes is 85 mm 1.8. If you switch to a DX mode, it it 127 mm , close to 135.
don't be funny, there is PRO lens by Viltrox, it's 75mm f/1,2 (eq. 115 mm for FF) - very close to your great expectation 🤣
Can you use it in FX mode with vignettes and then crop in post?
FF Nikon Z cameras automatically crop the image once DX lens is attached. There is a hack not to do that but you have to slightly detach lens. Not recommended.
Go to the menu and switch to FX image area. Though I don't see the point doing that, it's not like the lens is covering more than APS-C circle.
Would this one be equal to the Nikon z 40mm f2??
I haven’t tested the 40 f2. But the only thing that one may miss is the MP. Focal length between 27 mm on full frame and 40 mm native Z lens in full frame is the same.

I would be curious to know why your thing it is a nonsense. Photography is much about experience as about image quality.
super review
Thank you 🙂

Why is this lens considered a beginners lens?
still waiting for their 16mm lens
F/1.2 version? 😉

To be honest, the 27mm f1.2 impresses me more than 50 mm 1.8. You have to actually use to see the comparison.
