View Full Version : Fujinon T 400/8

I was considering the purchase of a Fujinon-T 400mm F/8

It looks like it is really intended for 4x5, but do you think it could also be used on 5x7?

It has an image circle of 220mm at F/22, which will cover 5x7. But will I always have to use the lens stopped down all the way to F/22 and beyond?
Or will it be possible to use larger apertures without too much light fall off at the corners?

Does anybody have any experience about using this lens on 5x7?

I have not used it on 5x7, but have used some movements on 4x5, without any noticable fall off at wider aperatures - but I shoot black and white, which is less sensitive to fall off. Given the depth of field, you may not find you are using small aperatures very often.

however for the occasional portrait it might actualy be desirable to shoot wide open to get a very shallow depth of field

Remember, Enrico, that at portrait distances you'll be using longer bellows extension, with a corresponding increase in the image circle. For very-tight headshots (close to 1:1), it might even cover 8x10.

(added) A key consideration is to make sure you have enough bellows extension available on your camera to work at the desired distance/magnification.

If you have the bellows, get the Fuji, compact 450mm. Bigger circle and less money.

...lighter and better performing.

That's a big (long) "IF" though; for infinity focus the flange back is 425.3mm. That enormous image circle is the achilles heal if you have to resort to an alternate means of extension:

As Eric says you may want to consider the Fujinon C 450mm f12.5 lens if you have sufficient bellows. If you do not have sufficient bellows there are ways around it. We have been discussing this lens and I am awaiting the arrival of mine as well as an Ebony extension tube set for use on a Technika type lens board to use it. I have 3 35mm tubes (105mm) coming for sufficient extension. Here is the link:

Absolutely. Lighter by far, smaller by far, and I think you are right about performance, too. I had a 400T a long time ago and I didn't like it much. The 450C is a great lens and good for so many formats. In some situations, as when imaging near the sun, beware of all that image circle. It may be giving you flare or burning a hole in your bellows.

the 450c is certainly a great lens, unfortunately I just don't have enough bellows (about 330mm)
and even using an extension lensboard is probably not feasable. to focus it at 2mt I would need to use almost 20cm of extension tubes

tele lenses are very susceptible to mechanical vignetting, so don't expect to gain much by stopping it down.

does the opposite also hold true?
that I will not lose much by opening it up?

That is my guess from using this lens on 4x5.

You should ask someone to make a test shot for you. While it may be true that the lens covers the stated diameter, you may (or may not) like the image quality near the extremes.

I had one, and it was quite sharp (http://www.kennethleegallery.com/html/lenses/index.php#400T) in the center region.

That being said, you might find Kerry's copy of the 1981 Fujinon catalog (http://www.thalmann.com/largeformat/ls-ts.htm) helpful: they list the lens as suitable for 5x7.

it looks quite nice

and btw there are some lovely pictures on your website :)

Hi all, Does anyone know the weight of the 300mm and 400 Fuji Fujinon T 8/300mm and 8/400mm lenses? Plus ive found literature that states that these lenses will work on a Linhof Technika 2000 camera, can anyone confirm this? Thanks

According to http://www.thalmann.com/largeformat/ls-ts.htm the weight of the 400mm T is 700g

According to http://www.hevanet.com/cperez/testing.html the weight of the 300mm Fujinon T is 415g

To determine whether the lenses work on the camera, you need to know the camera's maximum bellows draw. The 400T uses 250mm bellows draw at infinity. Lenses need additional bellows extension to focus more closely.

My 400mm Fujinon-T weighs 632 grams including caps and retaining ring.

The Fuji brochure lists the image circle of the 400T as 220mm at f/22, barelyaequate for 5x7 point blank, without movements. I've got a big book of Karakoram pictures taken with a Master Technika using Fuji 400T and 600T lenses. A tophat board might have been used with the 600. I use a Sinar monorail for long lenses rather than teles, but the Fujis do deliver quality images for 4X5 film at least, and at the present you can buy them way cheaper than a 450C. But the latter covers 8X10 with abundant wiggle room.

IIRC Tele lenses have increased mechanical vignetting when focusing near, but in that case image circle also grows so we need less the outer circle suffering the vignetting.

IMHO problem may happen when we use a T lens for close subjects that does not cover the format at infinite focus, but this may not be the case.

I used one on 5X7 for a few years but it had to be stopped down to at least f22 and it still barely covered. It is a very nice piece of glass but I would say to keep looking for an alternative. I am still looking for the 450C as that is the one last lens I would like to add to my kit.

Of course, the 220mm circle is specified at f/22, leaving 6mm room in each corner...

Hi, does anyone know about the Fujinon T 8/400mm lens barrel markings being in different colours? I’ve seen Orange and white?
