Hello everyone! I have been using the Nikkor 24/2.8D lens for the past seven or eight years (on a D80 since 2006, and an F80 before that). I just recently started noticing how bad it was performing compared to my other lenses (50/1.8D, 85/1.8, and recently a Voigtlander 40/2, all of which are optically very good performers). My technique may not be perfect, but with the same technique, I get much sharper pictures with all my other lenses than the 24/2.8D, so I am starting to like this lens less and less, and would like to replace it with something else, and possibly fill in the gap between 24 and 40mm. It needs to be FX. An upgrade to an FX camera is imminent for me. I have been using different film formats before I finally bought into digital in 2006, but somehow the DX format never grew on to me, and if the D700 successor is suitable for me, I'll buy that, if not, I'll go for a used D700. I think my only options are zoom lenses (I cannot afford the 24/1.4. I would prefer something more versatile and not necessarily so fast, and of course cheaper), which may not be a bad thing, as long as it performs better than my current lens. F/2.8 aperture is a plus, but I would mostly be using this lens on a tripod or in daylight, so not really a requirement. I have been considering the following lenses: AF-S 16-35/4, very good on my D80, but I'm not sure I need the wide end on an FX camera. A bit of a waste if I only use the longer end. AF-S 24-70/2.8, may be a bit too big for me, and frankly, still slightly on the expensive side, but if it is much better than anything else, I will consider it. AF-S 17-35/2.8, used to be very popular, but an old construction by today's standards. Not sure how much better it performs than my 24/2.8D. AF-S 24-120/4. I am very interested in this lens, I hear very little about it, and I feel like this may be very suitable for me as a walk-around lens, but again, I barely know anything about it, apart from the fact that it exists. Any third party lenses that I should be aware of? Thanks for any insights and suggestions.
