sigma 10-20 vs 15mm lmt and 21mm lmt

Ok, so here is my question. I currently have the sigma 10-20mm and the 21mm limited. I see that the 15mm is on sale on amazon, so would you suggest just selling the 10-20mm and get the 15mm instead? that way I have the 15mm and the 21mm (I know it won't cover the whole range, but is it really necessary? Thanks in advance

Only you can decide how important the 10-15 range is to you. If it were me, I'd sell the 21 before the 10-20. Take the 15 when size is the biggest issue, take just the 10-20 when you want as wide as possible. Either way, the 21 seems superfluous to me.

Look through your pictures and see what focal length you most often use with the 10-20mm. That may help with your decision. If you are often below 15mm then that 15mm won't be wide enough. I don't see the 21mm being very useful currently with you having a 10-20mm.

I would agree with birdoprey

I use exposure plot to evaluate my shooting style.

On average my sigma 10-20 makes up 20% of all shots, and 60% of all shots with the 10-20 are at 10mm, I think I would have a problem being restricted to 15mm.

I have multiple ways to cover 20mm so it would seem to be the least likely to keep IMO

Thanks so much, yes that's a great point, because i realized most of my 10-20mm shots are at 10mm

If you don't mind manual focus you could get an 8mm fisheye, and drop the 10-20, OR look at possibly getting the new sigma 8-16, use it for the really wide stuff, and get the 55mm to go with the 21. this way you get more range.

I noticed that I use everthing from 10 to 20mm I thought I used the 10mm more but after looking at my photos I see I'm all over the range.
Very handy lens, one of my favorites..

Sell both and get the Sigma 8-16mm.

Thank you
Russell
