It may be that the differences are a bit hair-splitting and that casual viewers wouldn't notice any difference in the pictures -- but one of the advantages of being enthusiasts is that we get to care about subtle distinctions that most people don't notice!


I suggest you be very careful of this sort of GAS impairing logic. It could be bad for your health ;-)
 
> Brian, is the plane in the 2nd shot a BF109? I'm obviously not a WWII war plane afficianado; as a kid, the BF109 and the P-51 were my favorite model airplanes to make.

Just saw this: The German Aircraft in the second shot is the very rare "DO-335", nicknamed "Arrow". It has engines in the front and rear, and could make almost 500MPH. The Smithsonian has a BF109 in the main Air and Space Museum downtown, but not at the Udvar Hazy Museum. They fave a FW190, AR234c (Twin Jet), HE177, and a piece of the HO-229 jet flying wing.

They have a P51B in its post-war racing colors.

As for the 50mm F1.2 vs F1.8, no it does not count. They are both "planar" formula lenses like the F1.4 lens. The Canon 50mm F1.5 is their Sonnar entry, much different from the Planar.

I have a Revell 1/32nd Scale BF109 kit still in the box, found at an antique store. Also a Spitfire MK1 to match it.

I will soon post some photos taken with a pre-war 50/2 in LTM. This would be my Sonnar 50 lens. Maybe one day I will get either a Canon 1.4 or 1.5 if I see the right offer.

DO335... HO229... AR234c...

I like the armor and naval stuffs too..

WWII modeling, another hobby that I don't have time and $ for, how sad.. :bang:

back to the 1.4 vs. the 1.5...

i have come, finally, to the candid realization that i do not like and have a hard time using the 50mm focal length.
and i don't like the size of the canon 50/1.4 lens. it's hardly a big lens but my small hands much prefer the smaller lenses.
so, once again, i'm thinking that i might try to trade the 1.4 for a 1.5 canon 50.
the 1.5 is smaller and it has a much different 'look' than the 1.4. this might assist in giving me the added motivation to try using a 50mm lens.
if no trade is available, i might try to sell the 1.4 and just buy a 1.5 lens.

any last minute thoughts that could assist me in my decision making process?
all comments welcome.

I know not of decision making processes, simply of the whims that steer me aimlessly through life.

The F1.4 is a classic 6 element Xenon made with newer glass, allowing it to "get-away" with so few elements. But we are still talking about an 80+ year old design. The Xenon has many more air-glass surfaces than the Sonnar. In uncoated lenses this gave the Sonnar a huge advantage. With lens coatings, the Xenon gained favor.

I like the Canon 50mm F1.5 and the Canon 50mm F1.4. The latter feels right at home on a VI-T or a Canon 7. The F1.5 feels at home on the Leica CL and Canon IIf.

The lens that surprised me was the Jupiter-3 after its reshimming. Very sharp and high contrast. That does not mean I'm selling any Canon's.

Brian, What is the best way to get a clean J3 that focuses correctly other than having to send it to someone to add shimming, as you seem to suggest?

Get one from Oleg.
 
I'm waiting for this lens to arrive from keh .. I'll post a full review on my website when I'm done shooting a roll. Probably early next week. With Thanksgiving pictures :)
 
Fredus - were you the one that snagged the Canon 50/1.5 in bgn condition at KEH a little while back?
 
> Brian, What is the best way to get a clean J3 that focuses correctly other than having to send it to someone to add shimming, as you seem to suggest?

Buying it from someone that has already re-shimmed/adjusted it to work on a Leica. Right now I am 6 for 6 on J-3's received that required adjustment. One with a shim too big, one that could be shimmed/adjusted using shim from a different lens (swap), two that could be adjusted using the built-in adjustable stand-off ring, and two that required new shims. I am using a "split ring" shim, that slips over the module for those. Cut pipe, file using a caliper, split the ring, fit it on. One was 4mm, another was 3mm! I am going to test the focal length on those, compared against a known lens. I'll set them up on a Nikon E3 on an enlarger stand and photograph a ruler. Change in focal length compared with the known lens "should" be proportional to the markings of the ruler. Longer focal length, less markings.

I took a series of photo's of the J3 disassembly and will post a repair thread this week.

None of this was necessary on my Canon 50mm F1.5's or Canon F1.4. One of the Canon F1.5's has it's rear module replaced and the second has a lens module on a different focus module. The shims follwed the focus module in every case; the lens modules were "That Close".
