Yashinon 50mm which one to keep?

[bluedxca93]

I have a dx in perfect condition i bought for 25 euros and a ds i bought forbthe same amount.

The ds has traces of cleaned fungus. It is sharp but lacks contrast.

DX looks a bit used on the outside but lenses are clean and it shots nice photos too.
Ds is sharper at infinity dx much more contrast nicer color rendering.

My current plan is to sell the ds. Reason: i want to buy a wideangle (ml line) and dont increase my number of lenses.
However im not 100% sure if ill miss the sharpness near infinity of the ds lens in future.
Do you thing the ds would be still on the market to buy if i change my opinion later? It is the standard lens bundled with the tl super.

And which adapter is good for the dx on canon ef-s? Need one with better ininity setting. Get the feeling another adapter may produce vetter results.

Do you really need the money? Otherwise I would keep them both.

On your camera, which I think is APS-c, the 50mm is a good portrait length lens.
I have a Yashinon- DX and have found it to be very good in this mode and for closer objects and scenes.
I don't think I have ever used it for infinity focus.
I don't have a DS lens so cannot comment on it, but the -DX is quite splendid for my use

Maybe the DX doesn't reach infinity or overshoots it. These lenses should be quite similar optically, so any differences are likely due to copy variation or maybe one has improved coatings over the other. If you digitally zoom in in live view you could check if the DX overshoots infinity.

@caspert79
Its just that i don't want to thave two 50mm. But at the same time it hurts a bit to sell it, even if the lens is very used.

@Oldhand i have used the DX for buoldings too and it seemed to be ok. Just really far away pbjects are not as sharp as the ds.

@D1N0 this would mean to ise an extra adapter for the dx. Yes after thinning it a bit results in 135mm and 50mm dx where sigmificantly better. Coatings are not exactly the samre. Post pictures if the two lenses itself later..

Ds



DX



Coatings look similar. Im keeping th dx for sure

It should be pretty easy to clean the fungus. If you can screw out the inner ring with a rubber block the front element should come out.

Bluedxca93, I admire your Spartan spirit! I am having difficulty to part with any of the many lenses aquired out of pure curiosity, while you are ready to sell one of the two lenses you like.

Back to your question, I agree with those fellows who suggest you to check the adapter. My copy of Yashinon-DX 1.7/50 is pretty painfully sharp at distances close to infinity.
