AF 50mm/1.8d or AF-S 35mm/1.8G

50mm's bokeh is indeed nicer as compared to 35mm.. BUT in term of versatility, the 35mm is very much easier to use. If you can't decide which one to buy, I would recommend you getting the 35mm lens. I have seen people ditching their 50mm lenses becos they find it difficult to use, especially during indoor events like wedding dinners, birthday parties, etc.
Even if you get the more superior 50mm f1.4 lens, it is also made in China.. :think: I can only say the glue used in China is not as strong.. :bsmilie:

If you don't like it, you can give it to me... I'll make sure I'll put it to really good use! :bsmilie:
Sure, it is not my favourite focal length, but for f/1.8 I'll have plenty of fun and sharp images with it! :thumbsup:

It's not true and a common misconception that a FX camera will be forced into DX mode whenever a DX lens is attached. By default it will, but you can override that default, and mount any DX lens in FX mode.
The original 18-55 kit lens for example, can be used from 24mm onwards without significant vignetting. So can the Tokina 11-16 at 16mm, Nikon 12-24 f4 from about 22 mm onwards etc.
the 35 DX that kriegsketten was referring to is one of the best performing DX-on-FX examples
For a people photographer, that lens performs without vignetting at close to normal shooting distances. Vignetting only rears its head if you focus it to infinity.In fact, the 35 f1.8 DX is admittedly even a tiny bit sharper at f2 than my 35 f2D! It is certainly more contrasty wide open. (I am looking at samples now on my laptop that I shot side by side 2 weeks ago).

Yes, I totally understand the 1st part abt overide. But to me it would not make any sense to use a Dx lens on an FX body without the overide. I hv used the T17-50VC on my D700 and yes if not overide I see a circular image. I also use to hv this 351.8G for a mth b4 selling it away cos I hv a 50f1.4AFD already.
My reply is in response to the context of this reply...
...that the 35mm is still 35mm on a FX when actually the usable part of the image is within the circular size which, when cropped, will give an equivalent of 52.5mm, I believe?
Lol that's really funny haha.
Hi
if you crop, then yes, it's 52.5mm....
For the special case of the 35mm f1.8DX, if used on a D700 in FX mode, it will still give the proper 35mm field of view. There is no significant vignetting as long as you're not focusing to infinity. In other words, you do no see any dark circle around the edges at normal distances. No cropping is necessary!
The entire frame is usable if you're doing people shots. In fact, this usable frame is actually a bit sharper wide open than my 35 f2D. As I've said, I've shot and compared both.
Different DX lenses behave differently. Eg the NEW 18-55 kit lens will NEVER work well in FX mode because you will always see the dark circle at the edges at all focal lengths. However, the older 18-55 kit lens can be used from 24mm onwards to give the proper 24mm field of view if you use it in FF mode.
Btw personally I didn't go for the 35 f1.8 DX because the focus feels a little slower, and also because I will sometimes use a 35mm lens to focus to infinity, hence I prefer the 35 f2D
I had the same dilema, I ended up choosing 35mm, just taking crop factor into consideration. 50mm was way to tight, I am going to spend a semester in UK and want to take some nice group shots and landscapes in low light .. i think 35 mm would be better for that. Although 35mm does slightly lack in bokeh battlefield, but the images are extremely sharp, I just love it for movie mode.

Thanks for the clarification:thumbsup: I did not get to use the 35mm on my FX b4 I sell it but I did test a zoom DX lens on FX hence my understanding of the dark edges. My bad.:embrass:

Did you see the images posted up on another thread here regarding 35mm f/1.8 on D700? They are a lot better then expected! :thumbsup:
Not targetting at you, but that is why some of us would want proof of usage through the images.
Certain assumptions (and sweeping statements) can be very misleading... Imaging someone who has the 35mm f/1.8 already and has recently just upgraded to FF body. When she/he reads the thread, the posts convinced her/him to sell the f/1.8 and get the f/2.0 instead... Of course, the fault do lie on her/himself for not testing the lens out first, but maybe she/he has not fully grasp the FF body functions yet?Granted Red Dawn has mentioned that it is only good for Portraitures, whilst f/2.0 is generally better for all uses. :thumbsup: However, I trust a number of us get big aperture lenses solely for the purpose of better isolation of subjects from the backgrounds, so this is good news for a number of us. Really affordable, wide enough for FF for portraiture, yet still usable as 52.5mm on DX body... Those who have both DX and FX bodies will reap the most out of this lens...

Not all DX lens cause bad light fall-off when attached to FX.
Some lens still acceptable, such as AFS 35mm f/1.8G DX, which is a very good anomaly.
If you wanted to see the beautiful vignette, You might try to attach your AFS 18-200 DX VR to FX body in FX mode,
