***First lens to challenge 2.4/35mm Flektogon***
Erm no supporters of Canon FD 35mm f2.8 and F2................................... |
Isn't their minimum focusing distance in the 30-35 cm neighbourhood? |
Well it's in this link somewhere, but my 35mm f2.8 focuses down to about 16cm to front of lens, or about 19.5cm to the film plane.
http://www.mir.com.my/rb/photography/companies/canon/fdresources/fdlenses/35mm.htm
They go for about £15-£25 on ebay and are a great bang for buck.
New FD 35mm f/2.8 Lens
The most popular lens at 35mm focal length and also the most economical. As a result of holding the lens speed at f/2.8, the overall length of this lens is only 40mm and its weight of 165 grams makes it the lightest lens in the system. As for the optical features of this lens, the concave element of the front group is of meniscus shape with a strong curvature.

I looked at the same page when I made the comment, thus the 30-35cm numbers. That's quite a bit more than the under 20cm of CZJ...
Your numbers of your lens must be a bit off as if your 35/2.8 focuses about 16cm in front of the lens, and the sensor/film is about 4 cm behind the last element of the objective which also is a few centimeters thick, surely the total is more than 19.5 cm... |

You are correct and I'm wrong......I still think in inches and the film plane is about 3.5 inches (not 3.5cm) from front of lens, which is about 9cms..so focus of subject to film plane symbol will be about 25cms

[quote="dakoo"]FD->M42 ? So can this be done to any FD lense ?[/quote]
I have an older but like-new 500mm Sears mirror lens that I think was made by Tokina. It came with a Canon FD mount. I unscrewed the FD mount and in its place glued a 42mm-58mm step-up ring. Found the glue at the hardware store- it is supposed to bind to metal. Let it dry overnight. I then connected that to a standard 42mm Screw thread-EOS lens adapter. The lens now focuses to infinity on my 7D and is a great lightweight long lens in my pack.

I found patent of this lens:
http://www.google.com/patents/about?id=NPU6AAAAEBAJ
It shows 8 different lens diagrams. The 28/1.9 has 3 elements in front group, so fig.10 is unlikely. It seems, that the 28/1.9 has 6 elements in the rear group and only two of them are cemented, so fig.1, 2 and 3 are unlikely, too. Front element is curved, so fig.6 and 9 are out of game... Fig.8 shows f/2.0 design. The last one - likely the 28/1.9 Vivitar - is fig.7:

Taken outside. Wide-open, very bad cloudy light. I couldn't pick WB right. This lens if very fast - camera went up to 1/3500s on 200 ISO. I must compare with other Komine, Kiron 2/28mm soon.

Another contender: Enna München 4/24mm. I am very pleased with results and short focusing distance really helps when shooting smaller objects. Multicoated version a bit better. And do check if all your elements are clean since this baby is prone to fogging due to plastic Ennalyt chassis (some lucky guys have metal version but not me).

Do you have a link to this paper or the title + authors? Would be interesting reading. |

I have not tried Distagon, but wonder if the key to Pancolart's statement is "short distance near macro usage". This is where I find my Flek to be a superior performer. At distance, the field levels out.

Well I clicked on your picture and it gets smaller, but clicking on other member's shots and it doesn't improve them much either. I'm using Firefox.

It probably depends on your screen resolution. You can try to open a picture in a new window and compare it to what you see on the forum page. If you won't see any difference just forget this  |

Distagon 2/28 does not magnify as much in nearest focus position as the Flektogon 2.4/35.
Like the Distagon 1.4/35, the Distagon 2/28 does however have an internal floating element that optimizes performance at all focusing distances, and which, to quote Zeiss words, makes so that:
| Quote: |
| the loss in image quality in the outer parts of the picture, otherwise disturbing, is largely compensated by this measure |
Obviously, if the closeup foscuing is used to photograph a flower, with narrow DOF and plenty of artistic bokeh, the corner performance is not so important.
If instead the closeup focus is used to photograph, say, a particular of a stone friese or of a painting, uniform performance from centre to corner becomes important.
So ultimately even in closeup use there is no one purpose and no one instrument. It depends on the use, and on the expectations as well.
