Advice requested re Canon 1.4 extender

Wandalynn

I already had a Canon 1.4x mark I extender when I recently bought a Canon 100-400 L II lens. The mark I extender seems to work fine with it but should I spring for a mark III extender for this lens? I had been using the mark 1 extender with the similar-vintage Canon 300mm f4 L. Cameras are EOS R and 90D and I shoot mostly butterflies, bees, and smaller nature--not many birds. Thanks.

Great stuff.  The depth of focus of the cat is very nice. 

 

I really could have used that EF 800 f5.6 to photograph some skydivers leaving the plane ast October.  Shooting from the ground looking up produces some interesting perspectives.

Downy woodpecker is very nice.  You better stick with the photography.  Smiley Happy

Thanks for your replies.  I shot the image below this past July with a 5D MK3, EF 100-400mm f/4.5-5.6 L IS II USM, EF 1.4x.  It was a hand held shot, possibly at shutter speed a bit low for the focal length (540mm).  Given the location of the single focal point on the deer, I'm thinking the focal area shown in the focus mask is shifted past a little bit.  I was thinking the flowers in front of the deers nose should be more in focus than presented.  Interested in comments.

Thank you very much Ernie, my stalking of Woody Woodpecker has been most frustrating.  And I am sticking with photography although I am very happy that my replacement of a $19 transmission part and 90 minutes of my time has resulted in a quiet and properly operating washing machine.

 

Gerry, I love the composition and color of that photograph! 

 

Although I can't tell for sure given the distance and fairly small area occupied by the deer, I think your focus is on.  The shutter speed is really too slow for a sure hand held capture with that focal length and with animals you are also depending upon your subject staying dead still (and the flowers not blowing in the wind).  I would let the ISO go up a bit and use a little higher shutter speed in that situation and I would still consider that even if you were using a tripod just to ensure that a flick of the ears or a twitch of the head doesn't cause a loss of sharpness.

I love it too. It is priceless and you need do nothing to it.

Thanks for your comments.  I live very close to this field and noticed this female deer entering and leaving the canola field from time to time. I was lucky to catch her and snap off a couple of shots before she took off to the tree line.  The light was fading as well.  All in all, it worked. 🙂

You are welcome and that field has beautiful color, great job of capturing Bambi in it!  Maybe I need to go out and find a nice friendly group of deer.

 

My woodpecker is taunting me.  He often is plying his trade on one English walnut near the west edge of my property so I set the a tripod up for it to see if he would show and within 20 minutes I heard his unmistakable tapping noise coming from almost directly overhead.  I was located under a tall hackberry tree and he was near the top.  Although a 2 foot long, 11 pound EF 800 f5.6 isn't great for handheld use I released it from the tripod and got a few photos of him before he flew elsewhere.

 

He is an interesting bird and our mutual behavior is amusing to my daughter.  She told me that she can already see what some psychologist will write in the future:  the subject was already becoming unhinged from the lack of sports shooting due to the pandemic and then he begin to imagine that the birds were conspiring to work against him and that is what pushed him over the edge into full blown insanity 🙂

The woodpeckers in my area are very elusive as well, my attempts to photograph them in the trees so far have been dismal, but I managed to capture one interesting snap of a wood pecker and his victim insect meal on the ground.  -Gerry

Nice shot but I think that is a Brown Wood Thrush.

Could be....I know very little of birds, but from a google image search it looks more like a Brown Thrasher.  The yellow eye ring matches.
