I’m going to inflict some of my thinking about rationalising my lens collection, and would welcome any comments and experiences anyone might have.
Firstly, as I described in my welcome post, I have recently moved from a Minolta 600si to a Dynax 7D, which I purchased body-only. For most of my AF “career” I've relied on a 28mm f2.8, 50mm f1.7 and the 70-210 f4 beercan. More recently, with a growing interest in very wide angle work, I picked up a Tokina 19-35, which I found myself using more and more.
Now I have the 7D, I am considering my options mainly to get back some of the very wide angle capacity I have lost with the change, and, since I’m doing that to rationalise the number of lenses by at least one and possibly to fill in some of the gaps I currently have into the bargain. Needless to say, budget is very much a significant criterion!
I figure that I will keep the beercan as I see no reason to change that lens. With that in mind, as far as I can tell, there is really no way that I can cover the range from very wide to around 70mm in a single lens. However, I could do so if I was prepared to accept say 16mm or 17mm as my widest lens.
I seem to have two major choices:
1. sell all my shorter lenses and replace with either the Sony 16-80 or 16-105
2. sell all my shorter lenses and replace with something like the Sigma 18-50mm f2.8 or the Tamron 17-50 f2.8 XR Di and at a later date consider a very wide zoom.
At this stage I’m tending more to the second choice. I doubt I can justify the 16-80 and, although the eventual two lens option would get me close to the same price, I end up with faster lenses and a larger overall range of focal lengths available to me. Both the Sigma and the Tamron seem to have impressive quality on paper, although I have read about some suspected quality control issues with the Sigma.
In relation to Sony, I’m a bit concerned about the reported corner softness of the Sony 16-105, which in any event seems rather hard to find in Australia. It isn't even listed on the Sony site! Another possibility is the Sigma 17-70mm f/2.8-4.5 DC Macro which fills in the gaps better, although the reviews are a little guarded about how much quality you actually get for the price.
So here’s my thinking at the moment – sell all my existing shorter lenses and replace with either the Sigma or Tamron 17/18–50 lens for now, with a subsequent wider purchase later. The Tokina 16-50 looks an interesting lens too, but sadly it’s not available for the Sony mount. Yes, I know I have a gap between 50 and 70, but then I have got used to that anyway!
I guess I could also just keep everything I already have and get rid of the 28, and replace it with a very wide zoom at some stage. That is obviously the cheapest option but I’m not sure the 19-35 range of my existing Tokina is sufficient and I do like the idea of a faster lens.
So, how is my thinking? Does anyone have any suggestions or observations about where I might be heading in the wrong direction? One thing I don’t know of course from my reading is how these lenses compare with my existing set up. I’d appreciate any comments on that score too, although I assume that for all intents and purposes that won’t be the issue it may have been a decade ago.
Thanks in advance!
