Hi,
As I've recently converted to digital, I need to get a standard wide, as my existing 35mm has now become a 50 due to sensor sizes.
Can anyone recommend a CHEAP 28mm?
Many thanks in advance
It depends on what you mean by 'cheap' and where you tend to shoot.
If you mean by cheap under 600$, and you want a new lens, I would stick with the CV 28s.
Presuming this to be the case, if you want small, shoot mostly in daylight, not in lowlight, then I'd get the 28/3,5 from CV.
But if you want to be able to shoot in lowlight, the 28/1,9 or 28/2 CVs are your best options. Both are great performers, yet the 28/2 has the slightly smaller size. But because you write you want "CHEAP", I would recommend you buy the CV 28/1,9. It would save you a couple hundred. That said, I do prefer the 28/2's rendering...but look at the M-mount group on flickr to view image samples and decide which you prefer.
On film, from what I have read and seen, the 28/2 has shown no focus shifting; but on the M8 it has shown some, according to Reid's Reviews. FWIW, I think the 28/2 CV and Leica 28/2 both have wonderful rendering in the center, being very close in performance at the image edging. But don't get the 28/2 as it is not the cheapest, lowlight CV 28.
