Default Got inspired from Frogfish

so I bought a Soligor 1.7x TC, it was quite cheap and I thought I could atleast get to know if I need the 150-500 bigmos or not
This is the soligor:


So, I just had to try it, I will have to practice a little more, but it does focus quite fast with just a little hunting in harsh conditions....so here it comes, the pictures Btw, the pics are taken at the end of day, the sun was going down so to keep it steady i had to raise the iso to maintain the shutterspeed...

Taken with the DAL 55-300/f4-5.8 (which would equal: 93,5 - 510/f6.8-9.86) at shutterspeed mostly at 1/800 (which gets iso 800-1600)

Really love the cat chewing on the stick. I'm impressed with these pictures for your first go round. I couldn't have come close to achieving those results without a lot of experimentation.

Hi Michael,

Some very good results, IMO. The Soligor physically looks a lot like the Promasters I've seen, so I'm thinking that Promaster rebadged the Soligor-made TC (or they both rebadged someone else's TC). The Promaster 1.7x has gotten some good user reviews, and samples I've seen are very good.

All of the gear here performed well at while pushing some performance areas to pretty much the extreme. It's a testament to the Kx that it will AF with such a small max aperture, the DA-L 55-300 that the optics can stand up to 1.7x TC use, and the Soligor TC that it could give you the magnification without compromising IQ to a significant degree.

How's the DA 55-300 working out?

Hi Ed,

It's nice to have a more compact and lighter alternative to the FA*300/4.5 for carrying around. I'd been using a DA 18-250, and being a tele guy, I rarely used the wide end, and at the same time wanted a little more at the long end. The DA 55-300 gives me wide enough to get context shots and the long end is fast enough to allow for some TC use. I'm thinking that this is going to be my default BIF lens, but will have to use it more to make that determination.

Thanks again!

Scott

I'm surprised you got such good quality - I wouldn't have guessed you were using a TC from these. Does get me thinking again about getting one. But there's other things to get first.

Michael you got me thinking also, your images turned out very nice

I'm pleased you got something out of my little test Michael !

This Soligor looks to be performing wonderfully - those are very sharp shots and shows you what 510 can do !

Scott - having used this combination (55-300 + AFA x1.7) I can't imagine it being able to focus fast enough it find a lock for quick BIF (maybe GBH ?) - I may be wrong though as I've never tried it for that purpose !

I would seriously consider one, but I can't seem to find them. Any suggestions on where they are sold?

Hi Kevin,

I consider my "sweet spot" for BIF at between 300mm and 400mm, so I'd either be using the lens alone or with an AF 1.4x TC. I just can't acquire moving birds in the VF fast enough at 500mm, and both zooming and manual prefocusing with a two touch zoom is a bit too much for my brain to coordinate anyway.

I believe that you're correct that the DA 55-300 will not allow the AFA to focus fast enough to get a good BIF sequence, especially if the bird flies in front of trees or something else that might confuse the AF system. It's a matter of just asking too much from the AF sensor at f9.9 max.

I'm really not much of a BIF shooter. About the only interesting bird to shoot in flight in my area is the Caspian Tern, and they are pretty few and far between. I usually just shoot gulls as an exercise.
