I too have found the 400mm f4 ED-IF (big white one) to be incredible.

Have you tried raising the battery contact tabs in the battery pack and the ones in the camera body (that the battery holder makes contact with)?
I have a 645n body that I raised the contacts on that solved a similar issue.
Perhaps over time these contacts become compressed and give intermittent power?

You might want to take a look at something in the price range of the A 45mm f/2.8, but much more versatile and really sharp - the A 45-85mm f/4.5

The FA version has many more reviews on this website and the two share the same optical formula. I have owned both at the same time at one point and no difference noticed (snapshots), but have retained the FA version for use on my 645N.

I did not know it was becoming easier to find - 200F / SP-200... might send it back and keep the 360B - a beautiful lens. Anybody need a nice 200F / SP-200 ?

I have a Nikon TC-16A modified to work with Nikon DSLRs to give AF (kind of, but quite good) and it seems to work quite well with the 360B. A nice combination giving me 480mm f/4.5

The 200F / SP-200 does not fit the 360B. The 360B has a protruding cylinder that interferes with the converter mounting, so while it would appear to be clear of the rear element, this cylinder (houses the rear element? need to take another look) is too long. But I appreciate the link to the review - I had not thought of gutting a 1.4 converter and seeing if that works with the 200F / SP-200 (kills any chance of infinity, but I wonder what the maximum I could focus out to would be. Nice idea!

The 200F/SP-200 does not fit the 360B model of the manual focus 300mm f/2.8 unfortunately. I have the lens and just received a beautiful copy of the 200F/SP-200 converter. Is anyone keeping a database of the serial numbers for this rare converter?

---------- Post added 02-23-2017 at 03:23 PM ----------



Sadly the unicorn-esque 200F (SP-200) does not fit the 360B... I found out just today when my 200F arrived.

Hi bluefin,

I have one in lovely shape along with the original hood (rubber). I find myself not really shooting landscapes with my 645n, so this has really sat (Pelican case) unused.

PM me if you are still looking and might be interested in my copy.

Strange behaviour with the FA 45mm and not wanting to autofocus... I have not experienced this.

I have been shooting with mine for many years now mostly with the FA 75mm (and sometimes with the FA 45-85mm, 67 105mm, FA 150mm and sometimes with the 67 M* 400mm ED monster). I purchased mine as a parts camera and sent it to Pentax USA (when they used to repair these) and had it completely overhauled (new shutter box and new mount were the main components) and it works really well. I have had two backup bodies, but never used them so sold them off recently.

I just received a DELTA adapter that was made for the AERO EKTAR 178mm f/2.5 (taken out of WWII era aerial camera). It appears to be made for an M39 camera mount, but since the camera mount is not permanent I am trying to have a camera plate made for the Pentax 67 mount so I can use it on the 67 bodies as well as the 645 bodies (via 67-645 adapter).

I had one up for sale that lingered for a long time and eventually sold. I still have a 75mm LS and a couple of 645 135mm LS lenses.
They are out there and lately seem to be popping up and then selling very quickly. Prices do seem to be going up, but given the scarcity it is hard to gauge with the LS lenses.

If you don't mind carrying around some extra mass, take a look at this 67 M* 400mm f/4

SMC Pentax-M* 67 400mm F4 ED [IF] Reviews - 67 Telephoto Primes - Pentax Lens Reviews & Lens Database

Obviously longer than the 67 M* 300mm f/4

I've found my copy to be beautifully sharp and crispy (nice contrast). I think surftodog (member here) is selling one for a similar price to a mint copy of the 67 M* 300mm would cost. Just a thought...

I've been wanting to compare the three for some time and had them all in hand a few years ago (A35, FA35, FA33-55)... but schedules were hectic back then (child, job etc.) so it never happened and I sold off all but the A35. I still have the A35 and now have a pristine copy of the FA33-55. Is there anyone in the DC area with a 645D or 645Z who might want to do some comparisons? Especially if you might have the FA35? As further incentive, if you also have the FA400 we can compare that against the 67 M* 400 ED-IF (beautiful, sharp lens).

One other note - under this topic https://www.pentaxforums.com/forums/48-pentax-medium-format/87027-post-your-m...at-photos.html you can do searches for various lenses and with the known limitations of looking at files under really low resolution it is still interesting to see what the FA33-55 can do.

Pentax 75mm + Sigma FT-1201 ?
Posted By yurihuta

It is a lens that screws into the front of a lens and not a rear teleconverter.

from Sigma's website (https://www.sigma-photo.co.jp/english/new/new_topic.php?id=496):

Conversion Lens FT-1201 for SIGMA dp3 Quattro

We are pleased to announce the development of Conversion Lens FT-1201 that is exclusively designed for the SIGMA dp3 Quattro.

When it is attached to the front of the lens, it magnifies the focal length of the lens by 1.2 times (60mm / equivalent to 90mm on a 35mm format), and does not change the f/2.8 aperture value. It consists of 4 ultra-high quality lens elements in 3 groups, and maintains excellent rendering performance while offering a different focal length and therefore more shooting possibilities.

If in Tena for a while some spots that might be worth investigating are Amazoonico (wildelife rehabilitation center - amazoonico rescue center) and Yanayacu (cloud forest, bring macro! - one spot that has trails and researchers that could help locate specific species http://www.yanayacu.org).

Amazoonico is a nice place with the chance to see and study some behaviours of species that are difficult to see in the wild when on a compressed schedule.

There is a matched (also works with some other 645 lenses) 1.4x converter that might offer better image quality and is slightly smaller, although does not give the reach of the 300mm + 2.0x combination.

Where in Ecuador are you headed?

If the Amazon, then a 645 300mm might be a tad short unless you hit hotspots like mineral licks (Amazonia birding tour: Parrot clay licks at the Napo Wildlife Center | Napo Wildlife Center) where group shots might work well with the 645 300mm.

If the Galapagos, then the 645 300mm might be just fine as the wildlife is more habituated to humans.

Purchasing a used MF camera

I've purchased several items (two dozen perhaps?) from Japanese eBay sellers. Never had a problem until the last one. The seller (under 500 feedbacks, 100%) did not disclose issues with the optics of the lens I bought (significant haze/fungus - listed as clean and clear) - that was eventually resolved, but there was major issues with this particular seller for getting my money back (he received the return, relisted and sold the item and dragged his feet on my refund). There are several Japanese eBayers who sell loads of medium format film gear with great feedback and I've never had an issue with these.
