Modified 4 lenses were compared under the same shooting condition, the distance from body to the object is 3m with 5,6 iris closure position. All the lenses are modified to adopt on Canon EOS mount by some means. These angles of view satisfy my own requirement for ordinary use if I don't rely on variable focal length equipment. They are EBC-Fujinon 21/3,5, MD-W Rokkor 35/2,8, MC Rokkor 50/1,4 PG and Sonnar HFT 85/2,8. In addition, I have prepared Macro Rokkor 50/3,5 with EOS mount, so the equipment has all prepared for new Digital Age. Let's go, go!

Leitz Super Elmar 16/3,5 wide angle lens has mounted on M9 by way of R-M adapter ring. Thanks to extraordinary focusing depth for these kind of wider one, a range finder coupling is not always required. When used at shorter distance within 1m, visual estimation would be enough for actual use. By the way, this Leitz brand lens is a sister product of Carl Zeiss Distagon 16/3,5, so is the OEM product. Writing of which, the color resolution has some amber color tendency as is often the case of Carl Zeiss product that I had been experience in Hasselblad 6 by 6 with Macro Plannar 120/4, but the color habit is within my acceptance at all.

As I mentioned before, old Minolta Rokkor 50/1,4 PG SLR lens has modified into adopt on Canon EOS digital mount, the same 50/1,4 for SONY Digital SLR costs 40,000 yen now! So, I have saved the money by my DIY work with Canon genuine body cap priced at 300 yen.
It is true that there is inevitable barrier not to be passed, the longer Canon flange back 44,5 mm instead of Minolta's 44,0mm, but this problem could be solved relatively easily by adjusting internal adjusting mechanism for compensation.

Hmmm, I cannot rely on the convenience of auto-focusing and auto-iris open & close, I dare choose this way not only for money saving but also for self controlling to get me back to the basics, checking the focusing and out-focusing depth one by one. 4 inch by 4 inch format camera had such kind of physical property without any arguments, once I had been in the world.
Too easy handling relying on auto-focusing system and anti-camera shake mechanism let me forget to check them and just shoot without deeper considerations in front of the objects. The best picture is very rare one, so putting the yell on my soul one by one is a necessary obligation for me.

Having been catching cold since yesterday, I'm ill in bed today, additionally the fortune score for today is only 52, so I'll stay at home all day long. The battery in Leica M9 was left behind by mistake, so no shot yesterday, how come?
Tele-Elmar 135/4(11851) is one of my favorite choice of tele-photo lens for Leica M bayonet body, though lens's weight is not ignored with thick glass element of Ernostar type constructive design, the depiction is favorable and with moderate strength. Latest model was changed into a parallel barrel cased but with no compatibility with Viso-Flex system.

Even a piece of small dust like chiselled metal powder or fiber dusts could cause fatal dysfunction of focusing mechanical movement, yes, that happened last night on SLR Minolta Rokkor 35/2,8 that had been modified to adopt on EOS mount. Probably some dust might have gotten into the helicoid groove in the way of processing. The importance is feel on focusing ring of manual device, the viscosity of lubricant there is indispensable item, not so soft but not too hard as not to produce backlash on the barrel straight moving guide. Unfortunately engraved scratches there formed on aluminum alloy might do harm on smooth movement of focusing ring even after cleaning? Because a focal length of35mm lens on EOS APS-C imaging format plays as a standard angle of view, this one should be survived even at any efforts. Micro particulate Teflon powder would be helpful for the purpose?

Foliage season is now, so I have a planning to shoot from a different direction from looking down on position. Camera device is now prepared for that purpose, I'll press ahead with this strategy. The result would appear here very soon. Takeda Castle at Asago in Hyogo Pref. is now prevailing now and the place is so crowded in number, my friend living there told me about that, but I don't want it because of too much tourism, I can only hope an incidental work however hard I might try.
