Great Pelican shots, so much detail!


Thanks, Paul. The AF does help. However, I have found it difficult to track the bird when flying by so quickly. The bird has to be in the center of the frame for the AF focus and the focus is still hit or miss. I do better with the AF Vectis 400. I try to set the focus range in advance when expecting a fly-by, which requires less adjustment for the AF. I've captured BIF using MF as well with the same technique, but success is even more limited. It's fun trying MF like in the old days when BIF was an accomplishment.

Nice squirrel, Matt. They take on different looks by region. Only 45 minutes from me there is one called a raccoon squirrel that we don't have here. Oddly, the ones we have in CHarleston resemble the ones in New Jersey.

I'm glad to see others out enjoying their mirrors.

I read that some of you with the LA-VE2 adapter have had trouble getting the 25-150 working. In my initial test, It worked for me, but then this past weekend I put it on and could not get it to work. I remembered what I did with another lens to get it working, so took both the lens and adapter off the camera with the camera powered off. I put the adapter back on with a firm snap into place, then the same with the lens. It started working and I had a good experience with it. Aside from the vignetting, I very much like what I got from the lens. The solution suggests the adapter may be having some issue with the contacts and the firm mounting corrects it. Make sense?

These are all mirror images from three different lenses.

1 - Vectis 400mm


2 - Vectis 400mm


3 - Vectis 400mm Five image merge


4 - Minolta AF Reflex 500mm


5 - Minolta AF Reflex 500mm


6 - Vivitar Series 1 Solid Cat 800mm

Erm , well , how can I put this ....
It wasn't Minolta messed my lens up , it was me !

I've had another look at the baffle , and had a look at the ones on all my other Vectis lenses ( I've got at least a couple of dozen ) and I realise what's happened .
A few years ago I had a look at altering the baffle to trim it to cut down on the cut-off / vignetting on a full frame sensor .
Turns out what I'd done ( and forgot about ) was rather than chop up the original baffle , I took one out of a 22-80mm lens that was faulty and chopped bits off that rather than cutting up the original .

The issue with the lens and baffle is that the baffle is needed to hold the electronic contacts , so has to stay . When you focus closer (IIRC) the rear lens element recedes up the barrel and as the baffles are basically a tube , this is what causes the problem .
The rear element of the 22-80mm doesn't recess anywhere near as much as the 400mm , that's why the tube isn't flocked .

Regarding a fix , I'll sand down the tube so it doesn't reflect the light and that'll sort it , though I'll still have the original baffle somewhere .

AF is spot on now and the flares gone.

A couple more that surprised me. These are with an A7RM3 and a generic Kalimar 1.4 TC, so MF. The IQ in these was kind of a shock with this combination. If the second photo looks a bit soft, the center of that bridge railing is 1845’ away per Google Maps, or over 1/3 of a mile.

Thanks gents! I figured you couldn’t have much more fun than an AF Reflex. What’s weird is the distance I shot those from. I think you could use it for street photography and shoot from the next block!

@Howard_S, that second shot is definitely spooky!
