I used to shoot 500/4.5 for about 5 years with K-5 first and then K-3 before moving to the newest 500/4 and D500. It is very good lens indeed.
Good luck with your sale!

Sorry. Personally I shoot almost 100% handheld. However, FA*600 is a great tool. Congratulations!

Item for Sale
Sigma 500mm f/4.5 EX DG APO Lens for Pentax K

Asking Price
3,750.00 USD

Item Location
Los Angeles (United States)

Item Description
I purchased this lens new from B&H in December 2012. And it has been almost welded to my K-5 first and then to K-3 ever since.

The lens is in excellent condition always being protected by RealTree camo LensCoat since month one. I was unable to find any scratches, scuffs, etc. Even tripod mount is clean, because it was always covered with long arca-swiss plate. Please see some images of the lens below.

Image for the thread:




There is non processed 100% crop of straight out of camera f/5.6 shot of dollar bill. The shot was taken from 25FL distance (12.5 yards/meters, tripod, SR off, MLU, remote).





You can find wide open (f/4.5) 100% crop here:

Some shots. Please note: I shoot exclusively handheld













There are a few links to a few more images taken with this lens:

Note: Bald eagle portrait is shot with DA*60-250.

During this years I developed my own way of carrying and shooting the lens. You can see it here:

If someone is interested in authentic Sigma 1.4X AF TC, let me know please. I do have both: EX and EX DG versions.








Sorry front element appeared to be a bit dusty :hmm:

As I remember one bird attacked another perching on a tree branch. Finally the first one grabbed the second by the beak and pulled out. All action took about a second and became visible on computer only.

I have shot wildlife with K-x, K-5, K-5IIs, K-3, and K-1. And I can tell you that K-3 produces more details (unfortunately more initial noise too) than all 16MP alternatives. Regardless what your own experience with Bigma tells you AF accuracy and image details matter a lot in wildlife shooting. For example I always try to focus on the eye. I simply don't keep images with soft eye appearance.







Second of all. K-1 is the great camera. It looks to me that AF of K-1 is slightly better then all of preceeding APS-C models. However, K-1 provides a 4.4fps vs. 8.3fps of K-3 (10fps of 7D Mark II and D500). Once I shot a fight of two humming birds with K-5 and FA*300/4.5. Humming birds are very territorial and fight a lot over their common places. In total I got 8 frames which means that with 7fps shooting range of K-5 the whole fight duration was slightly over 1 sec. Below is frame #7. Please don't judge it harshly. The shot was taken in deep shadow against the sun and the image was cleaned up extensively at PP. Anyway, I doubt that I could get such lucky shot with 4.4fps.



Regarding TCs. Following your logic that average wildlife photographer should be happy with A4 or Internet size images, why not just crop from highly resolving sensor? But, I paid my dues here too. Long time ago I even did a short study evaluating five best TCs available in Pentax mount at that time. I purchased FA*300/4.5 over DA*300/4 to shoot it with AF 1.4x TC. Then I switched back to pure 300mm when 1.4x AF Pz Tamron equipped lens was unable to AF steady on simple slowly flying osprey. To make it short. TC robs one stop or more from your lens. it prompts you to shoot at slower shutter speeds. If someone have a beautiful (but heavy by default) 300-400/2.8 lens it is probably OK. If someone shoots DA 55-300 or Bigma with 1.4X TC it is there own choice. Regardless how people praise "perfectness" of TC, there is no magic. It is a simple physics. TC adds an extra glass elements in optical path, that always affect final output. I'm not a snob. I understand that people shoot what they can afford or at least justify money wise. However, pro glass is simply PRO GLASS.
There are a few excuses when shooting an action. Dynamics of the bodies and appearance of the scenery may compensate for not good lens or technique. The wings on the next image are a bit soft. But I like it as a whole.




However, if someone shoots, let say, bird portrait, cleanness of details matter.





And now regarding your statement: You don't have to shy away from getting a shot just because your current gear is not an ideal set of compromises.
I don't. Sometimes I simply unable to get a shot due to well known Pentax cameras limitations. It is that simple.

Have fun,

SG

Thanks. I definitely need it :)

Love it! Would crop it differently, though.

---------- Post added 06-09-17 at 08:19 PM ----------



Good point! I never used it actually since I purchased it together with DFA 150-450. For our SoCal bright weather it might work. Thank you.
BTW, Swallows are great. I observed similar activities a couple of times. They are not easy to shoot at all.

I prefer full 24MP of K-3 or at least 20-21MP of 7DII or D500. With K-1 crop I shoot only Sigma 8-16, because I don't have FF UW lens equivalent and do not crop much.

Pentax HD 1.4x AF TC is APS-C only. I haven't noticed that and just waisted $500.

It is FF. However, for the wildlife I do prefer extra reach advantage of APS-C.

---------- Post added 06-08-17 at 06:55 AM ----------



I'm going to keep K-1 and D FA 150-450. 1.4x HD TC is useless though.

Hi guys,
It's been a while... It is my swan song, I guess. After lot of thinking I finally decided to move on and sell all of my APS-C gear including my beloved and very trustworthy companion of almost five years Sigma 500/4.5. There are a few shots with K-3 and Sigma, probably the last ones...

Happy Osprey (Sepulveda Basin Wildlife Reserve):




Rare for SoCal Red Fox (San Pedro)




Red-tailed Hawk Grounded :-) (Sepulveda Basin Wildlife Reserve):




Endangered Clapper Rail (Bolsa Chica Ecological Reserve)




Another Happy Camper (Balboa Lake)



Happy shooting to you all,

SG
