Great shots Amy! Very nice. We have had almost no small birds around this winter.

Got a few today. A bit of luck; went for a walk with the dog, saw the swans and were watching them. A heron flew in front and landed 40 feet away. Then an eagle landed in a tree. Light was dodgy, but the subjects were close enough. Sigma 150-500 K3.

Ken, that's a great series. You are one of the very best salesmen for the Sigma 500/4.5 on this forum. There are several of you.

Plus one.
Thanks Canada_Rockies and Travis for your kind comments, the Sigma 500/F4.5 is indeed a sharp lens, got a Nikon 500/F4 birder commented my Sigma 500mm sharper than his Nikon 500mm prime.

BTW- On behalf of Otis, I have tried numerous times to trade Ken a box of squirrels for just one of those gorgeous little Kingfisher birdies......with no luck.
So Otis asked me to post an open invitation to anyone willing to make the trade to send him one this Spring. He is expecting a multitude of baby squirrels, and will trade a box full, including one Nanny Squirrel to nurture them to adulthood for just one handsome Kingfisher.
lol

They are two different products... the 1.4 works seamlessly on your AF lenses , and believe it or not, that half stop makes a difference on AF. The 1.7 makes my A-400 into an AF lens (in really good light, it misses focus badly in low light). The 1.7 definitely gives you more magnification. Right now my feeling is I like the 1.4 for fast moving objects, BiFs etc. I like the 1.7 for the extra reach and resolution on more stationary objects, where I have time to focus and use the 2 second delay.

The 1.4 on the 60-250 is like having a whole new lens. The 1.7 on the 60-250 is the same as having an A-lens on it. You gain no advantage from the AF capability of the 60-250. In the end, I'm keeping both. For most of my shots, I'll use the 1.7 if I can and the 1.4 if I have to.

If I was going to have just one, I don't even know which I'd pick, you're giving up something important by not having either of them.
Do your tests indicate that the 1.7 offers greater resolution than the new 1.4? Thanks for all the pictures and analysis you have done.

There are lots of test pictures on this page... without getting totally anal about it.. it would appear that the longer the lens pointed at the test subject, the more resolution you have on the subject.... whether or not the TC is part of achieving that focal length doesn't seem to make a difference, on good lenses. I'll add that because on a not as good lens the CA and purple fringing gets amplified and can ruin your images.

If you look down on this page, you'll see most of what I've shot...

From today's trip to Algonquin Park.
When you arrive at the bird feeding parking lot, and there's no birds or squirrels to be seen, there might be a pine Martin somewhere nearby.

Just beautiful Norm. The first one is so clear that it looks like a stuffed specimen in a museum. The forth one is not what a mouse would want to see...! About how far away would you say you were when you took the pictures?

What's worn (wrong) with that darn spell checker thing-a ma-jig? I'm writing a nasty letter to Apple.

I'm guessing maybe 10 meters. The first one was taken at full reach 350mm, the rest were taken at 198mm, I really didn't need the 1.4, but I had great light so no need to take it off.

Another Kookaburra from my backyard, managed to get pretty close. I only shot the head since it was sitting on an ugly chain link fence (also because it wouldnt have fit in frame ).

500mm on the Sigma 150-500mm OS HSM & K5II, uncropped

I would say there is no clear difference between the two lenses in sunlight. I don't know what 500mm Nikon prime he has. The other day I was chatting with a Nikon shooter I know. He is one of the best wildlife photographers I know. The sun had just fallen under the tree line and we started photographing herons and egrets just to mess around. We zoomed right onto the eyes with our screens almost as much as the cameras would let us. He had more fine details than my camera. He was using a D800 and he already had aligned his combo with Lens Align. His FF camera captures lower light more efficiently than the K-3. In sunlight I don't think we could have seen any difference. Of course, his camera is almost twice the price of mine.

Cross-posted from the Q sub-forum. Taken with the Q classic and Minolta MC Tele Rokkor-HF 30cm (300mm) 1:4.5, which gives an equivalent FOV of about 1650mm. This is not a crop, but the full extent of the image. Not bad for such a tiny sensor.
