Old/alternate lenses, adapters, and lens mount conversions.

yours is a 24TSE ?

ryan

Yes. I have the 24mm MkI. I might just modify the screws for it to be able to tilt horizontal instead.

BTW, anyone heard of people converting Leica APO-extender-R 1.4x TC or Contax Mutar III 1.4x TC to accept EF lens and mount on EOS camera?

The FF gives me a more generous blur than a crop sensor. But still workable Just that my widest 24mm will not be as wide as it seems

A Tilt Shift Fisheye affair

Mamiya 24mm FE + Mirex Tilt Shift adapter.

Photo from gorbelabda's Flickr

The Mamiya is a hefty fisheye meant for the 645 format, that looks almost unwieldy on my
5D. Beautifully sharp and contrasty. Largest aperture at f4, weighs about 780 + gms.

It cannot tolerate the full 15mm shift on Mirex without hitting the edge. 10mm is optimal though u can push to about 12mm. It has obvious CA on closer inspection but easily fixed with PP.

Not an easy lens to source for, and took me months before a very kind gentleman sold me his minty copy locally.

Here was the list price in 2004. http://mamiya.co.uk/library/645ProTL.pdf
It will probably be tough to find a good copy at the same price

Very impressive Ryan. The Mamiya fisheye looks awesome.

My favorite lens on 5D, Zeiss CY 85f1.4, shot wide open.

I can attest that's one hell of a fantastic lens. I love it to bits but have sold it along with my canon system... well, still have the metal hood if anyone is looking / interested!

I am interested if your price is not so stiff, haha.

Earlier this year when I started converting my R lenses to alpha mount, the 28mm R was one of the first to be adapted. Despite the fact it is about 27 years old, this lens still performs well when stopped down to f5.6-f11.00 for landscape use. This lens was launched in 1970. There is a bit of vignetting in the extreme corners in this test shot. Previously, with the DMR, there was no edge or corner issue as it was 1.37x sensor.

This lens very beautiful looking but also very expensive. I think together with the adapter will be around the range of Olympus OM 24/3.5 PC. I think I won't go there so will only drool over your photos.

This is not bro. What is steep is the lens hood for my canon 50mm f1.2 LTM... I paid a whopping $250 for it! :dunno:

Is this the one with 48mm filter thread? I had this and it was outstanding on APS-C but when I switched to FF it vignetted even at f8 and I sold it. Heard that the later version, made in Canada E55 rom version is the best but very expensive.

Anyway, Mr Ng, your shot is really outstanding and I love the Leica image rendering very much, very natural.

Does the 88mm hood look very large on the lens? I have a small cute 67mm metal hood for it and it goes very well.

Some hoods are just overpriced. Someone wanted to sell me a Contax N 50 hood for US$200. I didn't bite. But then if they cannot be found anywhere else then no choice. The lenses really looked better with the original hoods. If function is more important than aesthetic, then any hood that fits will do.

Just append this cinemod url here should anyone be interested.

1) the part that makes me wonders is the de-clicking of the aperture. I spent so much time to make sure my manual lenses click when one of them are slightly smooth and soft. While I understant the need to not have the click for cine lenses. Does it means simply the removal of the ball-bearing. Seems like a simple thing to do for US$250.

2) Why do cine lenses need to have the follow focus gear. What is follow focus gear, just a ring to turn the focus ring or is there something more?

Hi Anthony,

Yes, this is the Series 7 or 48mm version. Yes, it does vignette but by f8.0, I find that it is acceptable. Since I shoot mainly at f8.0 or f11.0 for landscapes, this is not much of an issue. With an APS-C lens the performance should be very good. Bear in mind this lens was introduced in 1970. The 2nd version of the 28mm, has a built-in lens hood. As far as I know this was only manufactured in Germany. According to Erwin Puts, this version is an order of 2 stops better than the first version and with a floating element, has better close-up performance. Unfortunately, this version is getting very expensive. In fact, I have replaced this lens with the 16-35mm CZ for most uses, except when I need a lighter , smaller lens.

Mind sharing some photos of the CZ16-35. I would like to see how it compares to the N17-35. While it is branded Sony, I am sure the bros here will not mind since anything that is Zeiss is considered alternative.

bro. the other old mamiya lenses are less expensive ma. together with the adapter u got more tilt shift lenses than what canon / nikon offers at a steal .

( didn know the oly 24/3.5 is that ex though )

Maybe this is one good reason to use f1.x manual focus lenses on digital cameras.

http://www.luminous-landscape.com/essays/an_open_letter_to_the_major_camera_manufacturers.shtml

Quote:
"If the light loss is so significant, how come we do not have great numbers of photographers complaining about severe underexposure at large apertures?

This graph clearly shows that camera manufacturers “game the system” by increasing the ISO without the photographer's knowledge.

If the camera is automatically going to increase the ISO due to a significant light loss at the sensor, does it make sense to buy bigger, heavier and much more expensive large aperture lenses?"

I am assuming the camera manufacturer program the ISO increase when you set the aperture dial to f1.x . So if you are using MF lenses, just don't program you AF chip less than f2, then you won't get this "auto ISO increase". But may suffer from more light fall off though. This is interesting. Should try it out.

Extract from various para:
"By the way, this type of light loss is the main reason that modern lenses designed for digital photography place great emphasis on the direction of light rays behind the lens. It is also an important reason why Medium Format backs (often used with camera movements such as tilt, rise/fall and shift) and the Leica M9 (with lenses that produce mostly oblique light rays) use CCD sensors with a very different structure, rather than CMOS sensors.
......
In fact, is not even clear that large aperture lenses will deliver a shallower depth of field as intended. The DxO measurements to date prove that the marginal light rays just don’t hit the sensor."

If this is true, I am beginning to deduce a lot of things. No wonder Sigma has such a large front element for light gathering ability. Now this bokeh thingy is making sense. Seems like really have to keep a lookout for cameras using CCD instead of CMOS.

If only someone working in the sensor industry can come out to "break the magician codes"

Now Leitax has came up with a native EF mount for Cy lenses. Better snap these lenses up before price increased.

couldn't sleep today...so posted a few more Qs....

Anyone has any glass with thorium elements? Are these radioactive lenses desirable or not?
