I need help! I bought a Sigma 70-200 f2.8 at the recent big photo show in the UK. There was a deal and I thought "why not?" since as you all know, my Panasonic 70-200 f4 is dead. They didn't have it in stock at the show so it was shipped to me. It arrived last Weds and it's sitting here now in its box, unopened with a returns authorisation form stuck to it. So why is it unopened and awaiting return? I guess to a certain extent it's buyer's remorse syndrome, but there is also some rational analysis going on. Here is my dilemma:
- Looking at my shots in 2025, I see that the breakdown in lens usage is roughly this:
But I've now got the Sigma 20-200 so I do have 200mm covered, just that it's at f6.3, not f4, and there's no OIS/Sync IS.
But, if I examine the apertures used with my 70-200 f4, then I get this:
The f4 shots are mostly aircraft in flight (with a smattering of wildlife, but not much). As a result, they are all hand held and most at a high shutter speed. They are all at or very near 200mm and in fact, most of them have had a decent amount of cropping (i.e. I could do with a longer lens for aircraft!).
So, in truth the 20-200 will cover 75% of the things I used the 70-200 for. But it won't make a great lens for aircraft - it's a bit too slow and it lacks OIS (I know that OIS won't help a lot, it will help with viewfinder stabilisation and will deliver a little improvement in camera shake).
So I'm left with the decision:
- Is spending £1200 justified for the relatively little need I have for a fast lens in the 70-200 range?
- Would I be best using the 100-400 that I recently acquired for aircraft and accept the slower aperture?
All the logic tells me that the 70-200 f2.8 really isn't a priority, but OTOH a good fast 70-200 is a sort of invaluable lens in a general purpose kit, so my emotion tells me to keep it. I'm sure I'd find things to photograph for which it's suitable (a variant of "build it and they will come"!).
What are your collective thoughts?
- Looking at my shots in 2025, I see that the breakdown in lens usage is roughly this:
- 24-105 - 41%
- 70-200 f4 - 18%
- 35mm f2 - 15%
- 14-28 - %13%
- 20-60 - 9%
- 50mm f1.8 - 4%
So on the face of it, the 70-200 is my second most used lens so getting a replacement makes huge sense. I can also see that 45% of the shots are at 200mm.But I've now got the Sigma 20-200 so I do have 200mm covered, just that it's at f6.3, not f4, and there's no OIS/Sync IS.
But, if I examine the apertures used with my 70-200 f4, then I get this:
- f8 or f11 - 76%
- f4 - 23%
Not too surprisingly, the shots at f8 or f11 are all landscape shots. Some will likely be taken with a tripod (but not all). And whilst the IQ of the 20-200 at 200mm isn't quite as crisp as the 70-200, it's actually pretty good. So, there is really no point in a 1.3kg, £1200 lens for my landscape use.The f4 shots are mostly aircraft in flight (with a smattering of wildlife, but not much). As a result, they are all hand held and most at a high shutter speed. They are all at or very near 200mm and in fact, most of them have had a decent amount of cropping (i.e. I could do with a longer lens for aircraft!).
