I think you're doing just fine with those 2 Tokinas... The A400 is practically my wife. Since I've had it, I've taken more snaps with it than any other lens.

It also works a treat with the A 1.4x-L Rear Converter...

I found an A 400 on the marketplace and am looking to purchase it. It's not that I want it. I NEED it

Is LBA as bad among Fujians as Pentaxians? After all, the X-mount allows for far more lens choices...

It's worse. Or maybe the same. We're all cut from the same photographic gene pool
They call it GAS. Gear Acquisition Syndrome.
I also have way too many Billingham Camera bags. But I like doing YouTube reviews on them.

I tried to get the best results of the A400 on my test scene. I noticed when expanding these shots as I did, it is very tricky to get shots without any movement of your camera / lens combination. Although I have a well founded house with concrete floors, a passing car results to visible shaking in your screen at 16x magnification.

So instead using the tripod platform of the A400 lens I screwed the KP itself on my tripod and while the front of the lens rests on the window framework. That creates a double support and a more steady situation. I used the timer at 12 sec to avoid any shaking.

I developed the shots from RAW with just a tiny sharpening and a +25 Contrast.

This shows the A400 does have decent center sharpness even wide open with an optimum at F11.

Remember, focussing has to be done extreme precise and a solid tripod is neccecary for achieving this sharpness!

A400 wide open:



A400 at F11 (sweet spot):



A400 wide open extreme crop (eq. with a 3000 mm !):



A400 at F11 extreme crop (eq. 3000 mm !)



So the A400 really has great resolving power at ideal circumstances!

Looks great! I'm looking forward to getting this lens. Then I'll have 3 legacy long lenses. Tokina 400mm 5.6, 100-300mm F4 and the Pentax A 400 5.6.

All three lenses for less than $400 dollars.

Just bought the Pentax A 400 on the Marketplace over the weekend for $260 in excellent condition. I'll test it out once I receive it sometime this week. The only issue with this particular lens is that the filter threads on the front of the lens are bent slightly due to a shipping problem from when she first purchased the lens. I'll see if I can rectify that once I get the lens in. If not, no big deal. I tend not to use filters on my long zoom's anyway.

I received my Pentax A 400mm lens today! It's late in the day and no sun but I was able to do some preliminary testing. So far it is sharper and more contrasty than my Tokina 400mm 5.6 so I am happy as this lens cost me 6X more than the $40 dollars I paid for the Tokina.

I'd wrote some sentences about the definition/categorisation of vintage/legacy lenses here:

Yea I made some replies in that very same thread.

it's a funny thing - there almost seems to be a distinct divide in the Fuji crowd; either you own almost exclusively no vintage/non-Fuji mount lenses, or swing widely in the other direction, where you own almost exclusively non-Fuji lenses and have a buffet of adapters for your LBA....

Not that I hang out a ton in Fuji forums, but I do occasionally, and it seems like Fujians - understandably - really like their native glass.

There is a fella on DPR who does nice wildlife work with one of the 150-600's on his X-T3, using the Fringer adapter. You could actually buy an X-T3, 150-600, and Fringer for about the price of a DFA 150-450.

Yea I was part of that thread too. I think the Nikon 150-600 looked alot better than Fuji's 100-400. But you're going to have $1,900 wrapped up into it. Ok if you're making money as a wildlife photographer I guess.

Well so far the Pentax 400mm F5.6 is sharper and has more contrast and better rendering. The Tokina 400mm is no slouch however and is a bit smaller. But the focus ring on it does not have much travel. If you sneeze you could lose focus. The Pentax is not that way. It has much more travel on the focus ring and is much easier to focus.The Pentax seems brighter as well.

Here's a quick picture with the Pentax 400mm at F11. The bird was already quite sharp so not much needed in Capture 1 to sharpen the image up like I need for the Tokina.
