I continue to be amazed that with a D30 I can see the difference
that primes make in my photos. Just yesterday I compared 13X19
enlargements of images shot with my beloved Canon 70-200 f4L zoom
(That I have demonstrated is slightly sharper that the 2.8 IS
version) at 85mm, with identical shots taken with a Canon 85 1.8,
and the prime’s images were crisper… So it should come
as no surprise that I’d recommend sticking with primes.
I'm a zoom kinda guy but after familarizing myself with MTF tests, graphs and charts.... I'm convienced that one needs both zooms and primes in their lens kit. Currently I'm running four zooms in my kit:
Sigma 24-135mm
Canon 28-70 f/2.8l
Canon 70-200 f/4.0l
Canon 75-300 F/4.0-5.6 IS
I was going to add the much vaunted Canon 70-200 and the 100-400mm to my zoom lens kit and then discovered MTF charts and graphs. Well after learning to understand what the charts were trying to tell me, I converted from the zoom school of it's the only way to an honoree of both camps. I have a primary loyalty to sharpness and the propensity to use the proper lens to get the image recorded.
So on my wish list that I'm currently starting to fill, I've added six primes and a zoom of "Must Have" lenses and decided that I don't need the 70-200mm f/2.8 or the 100-400mm IS zooms:-0
Zooms:
Sigma 15-30mm
Primes:
Sigma 14mm f/2.8
Canon 85mm f/1.8/f/1.2
Canon 135mm f/2.0L
Canon 200mm f/2.8L
Canon 300mm f/4.0L
Canon 400mm f/5.6L
Not sure which 85mm to get if either. Why? Because the performance characteristics are not up to my liking so I might go with a third party Tamron 90mm f/2.8 macro whose charts I'm much happier with as the lens for this situation/need.
To me, the purpose of primes is to shore up the weaknesses of the zooms I have aquired, much like bracing in a well designed bridge. The sum of the parts makes up the whole is the idea.
Right now, I'm deciding between many possible choices that are somewhat affordable, based upon the monies I have left. The following choices are the combo/individual packages I feel I can afford.
1. Sigma 14mm and the Canon 135mm.
2. Sigma 14 and the Sigma 15-30mm
3. Sigma 15-30 and the Canon 135mm
4. Canon 200mm and the Canon 135mm
5. Either the Canon 300mm or the Canon 400mm
I might add the EX 1.4X II to the mix of I wants but the EX 2.0X II is definitely out as I consider it a bad choice unless you're a desperate pup.
I made a linear chart/graph that listed all the lenses I had, their ranges, adjusted for 1.6X EOS D30 multiplier to see where I was at lens wise. I filled the weak points in with primes that shore up, bridge bracing style, the linear chart for the lengths of each of the lenses.
I'm leaning towards choices 1, 3 or 4 which seem to fit the current type of image capturing that I'll be doing with these lenses as 5 can wait for the start of Major Minor League for my teen son. Number 2 is too restrictive on one end of the mm chart. Let's see 1 will fill in the left and right end of the first third of the linear lens graph. Number 3 will fill in both the left and the middle nicely. Lens group 4 will help fill in the rightside of the lens chart nicely, also.
Suggestions as to what direction I should take?
Thanks
