Bigma or.....

It's tax time again and the CO of my current ship (read: wife) has allotted me the funds for a new lens. After much research and reading of reviews from from Pentax users as well as Nikon, Canon and Oly I have pretty much decided on the Sigma 50-500. It will suit me well for the wildlife photography that occupies my free time as well as replace my new to me, but old Lentar 400mm f6.3 manual prime.

As I said, I have pretty much made up my mind but if anyone could suggest an alternative to the Bigma I am very open to researching something that I may have overlooked. Spending over $1k does not happen that often for me so I want to make a wise and informed decision. I respect the opinions of the folks here and that is why I am soliciting input.

Thank you all for anything you might offer!!

This may not suite your needs, but I have 2 different options for getting reach.

Note this does not mean people have not taken great shots with the BIGMA, just I have a different approach.

I use both an SMC 300MMF4 plus SMC-F 1.7xAF TC and a Sigma APO 70-200F2.8 EX (non DG Non Macro) plus 1.4x and 2X TCs

the reason I like the sigma 70-200 F2.8 is that if I don;t need the lenght, I can take the lens on it's own and be 1-2 stops faster than the Bigma between 70-200mm. I have used the lens a lot on it's own for indoor sports and performances where all I needed was 70-200 and the speed was very important.

Ideally, I would like something like a 500mmF4.5 (i.e. just a little bigger and faster) or 300F2.8 plus TCs (and I thnk I would keep my sigma TCs for this) but that decision is a little ways off.

For me, given the lenses I already have, the bigma is just not enough of a difference to make it worthwhile.

As Lowell I have the older Sigma 70-200/2.8 with the two Sigma Apo tcs. While this a high qualitiy and versatile combo, the problem is, that the current HSM Sigma lens, will not AF with the tcs. So you need to find an older pre-HSM Sigma, which is not that easy. Also, you would not get a new lens with warranty etc.

Besides that combination I can really recommend the Bigma, using one myself, besides the 70-200. I use the Bigma much more than my primes, because it is so versatile. I do use the 300/2.8 with a 1.4x tc, but not as often as the Bigma. And my old K 500/4.5 is so much more cumbersome to use

Be prepared to always (well, almost always) use a monpod with the Bigma, as it is heavy and not a fast lens and even at higher ISO setting camera shake may ruin images (but that is the case with anything above 400mm). Also you need to practice focusing with the Bigma, because even a slightly off focus will degrade image contrast noticeably. This is probably the reason for the complaints about lack of contrast on the long end, you find sometimes on the web.

So, thumbs up from me for the Bigma - but its your money.

I have been OCD'n on a long reach'er too. I agree the Bigma is looking good but if you can let go of afew more bucks the Sigma 100-300 F4 with 1.4 APO tc might get better IQ. At least thats what I am getting from the reviews and such that I have been reading (for what seems like years now). Have ya looked in to the Sigma 100-300 ??? Good luck I know its tough to pick one.

What does "OCD'n" mean?

Whether a 100-300 + tc produces better results, than the Bigma on its own, I don't know. I have only used the Bigma and I do not trust "reviews" or "opinions" from sources I do not know well. In these sources you'll often find the complaint I mentioned, about the lack of contrast of the Bigma. But this is rubbish. It is a lack of focusing accuracy be the user, but who would want to confess that? (I have lots of images, where the focus is just off - and then I get this lack of contrast too.)

I have both the Bigma and the 100-300mm f4 (with 1.4x TC)

The Bigma has the advantage of a wider focal range but the 100-300mm and 1.4x combo is better IQ wise (not by a large amount but enough to notice). Infact I would say the 100-300 and 2x TC is just as good as the 50-500mm and you gain extra length.

Thanks for all of the info. Now I look at price and find that the 100-300 f4 is running $1200 and the 1.4 tc is $250 where the Bigma is about $1050. Is the extra $400 for the 100-300 and tc combo worth it....????

Once again, thanks for the info!!

I've viewed the Bigma vs the Sigma 100-300mm with tc photos. Much better overall results with the 100-300mm +tc. If you want versatility, Bigma. If you want IQ, Sigma 100-300 plus tc. If price is the problem, get the 100-300mm now and tc used, later on.

Very informative folks!

Thanks for the input. I think I'll do some more thinking and maybe look for the 100-300 used and think about getting the tc new. Decisions decisions.........


Once again, THANKS!!

Thanks for the compliment. I'm biased towards the f*300mm. it is so sharp and very compact. If you think you can live with a prime, I'd look at the F*, FA*, or DA*300mm lenses. The Sigma 100-300mm is next in line to those in iq.

Bigmas are quite useable hand held. I use mine mainly as a 500mm lens and hand held. As you are shooting wild life you already know of the need for reasonably fast shutter speeds on the off chance they decide to write their own script and move at inopportune moments.
