Perar lens

No, I do not have one. But I try to be organised and invite the Perar owners and others interested here. The other thread, namely the one about weird lenses, is too much taken over by the Perar details, shipping and other stuff, IMHO.

 

Or do you insist that Perar is THE weird lens? :)

It is always difficult to judge from uploaded small .jpg's but I wonder what the attributes of the Perar lens are, over and above other M-fit 35mm lens? (Aside, obviously from it's compact dimensions). After all, people seems to be pretty excited about it. Colour rendition? Corner to corner sharpness? Lack of distortion? Bokeh? DoF? etc etc. Just curious!

Well looking at the above examples it has quite some fall off in the corners and looks sharp like the old triplets...

 

further I read at rff.com that the buildquality is quite bad and some examples came with damaged lenses at the back

The interest in this lens shows that there could be a market for a collapsible/ultra compact 35mm lens from Leica. I know they probably have enough on their plate at the moment, it might work out too expensive and they would point me towards the 35 Summarit. Having already one Summarit (a 75mm), I am not a huge fan of their rendering. Personally I might find the f3.5 of the Perar just a touch slow plus the other limitations of a Cooke Triplet (flare, coma, small aperture diffraction etc). If I could be sure of getting a good one, I would buy a 35 pancake Skopar in a flash but my experience of CV lenses has been so poor, that I feel I would be nuts to risk it again. I suppose I could go down to Poole and try one or more actually on a body. I was using a 25 Biogon in South Africa recently and taking no other lens with me for the whole day. It was really nice not lugging tons of stuff around. I do have a 35 ASPH Summilux but being a chrome/brass one, it makes for quite a heavy combo with the M8 or 9.

Personally, I don't know the lens is shockingly good, however I was very interested in the ability to make my M9 with a 35 literally fit nicely in a jacket pocket. :D

 

Have been shooting with a 50 1.4 on the dSLR with vertical grip for work lately and have been reminded just how wonderful light and comfortable the M9 is. :-)

Got it! Parcelforce finally delivered. It's tiny, seems to be beautifully made, mounts very smoothly on my M9 and seems to have the capacity to deliver rather well.

 

A couple of the first shots taken (while at my rather squalid university desk). No aesthetic value, but it does give a sense of out-of-the-box LR defaults colour rendering + resolving capacity - 800 ISO fully open in crap mixed life. Also, I've not noticed any vignetting on other shots. I'll post more this weekend (it promises to be sunny up in Cheshire where I am for the next four days) :)

 

Really, really pleased.

Chris,

 

Unless I am seeing something that is not there, there seems to be quite noticeable vignetting, particularly on the first shot. Now I am guessing that the nearest equivalent lenses, the Leica 35 Summarit, the Zeiss 35 Biogon C or the Skopar 35/2.5 Pancake II would show much less vignetting at f3.5. It may be that this is something that one has to live with to get the compact dimensions of a simple triplet. I have at the moment got my name down for one of the next batch of Perars but I am not sure about this.

Wilson - the apparent vignetting was to to with a desk light directly above the apple so there was very uneven illumination. Two examples from the train journey from London - hyperfocal and very slow shutter speeds, so don't use them to critique the sharpness - however, it does help re vignetting... More to follow after I've been for a walk this morning. I think you can be confident that this isn't a serious issue... :)

Out for a walk in the National Trust park at Dunham Massey with the Perar 35. Very pleased. No problem working with gloves on, no flare issues, no vignetting, OOF areas pleasingly rendered, in focus areas sharp and clearly dilineated - nice contrast.

 

I attach a shot below + have posted a small set to Flickr. I'll probably add to this over then next couple of days.

NB apparently duplicated shots are there to show different renderings fully open and closed down to f16.

 

Thank you Mr Miyazaki for the design and manufacture - thanks to Dirk at Japan Exposures for excellent service.

Finally a brick wall! Very happy with centre sharpness, but with the lens open the corners and edges are fairly soft. I've not seen what it's like stopped down - I'm not that excited about photgraphing brick walls.... :)

However - this does give an idea. I've not got my cron 35 mk IV with me to compare - I might have a go at another wall when I'm back in London.

This Perar seems to be the first ever 35mm triplet sold for 36x24mm. I can't find or think of any others. The cheapest Rollei 35 models had a 40mm triplet, and there have been many in the 45 to 52 mm range including some cheap standard lenses for Exakta/Edixa/Practica - but 35mm?

 

I'd be interested to be proved wrong.

Chris,

 

The rendering is certainly better than my other ultra compact M lens - the Leicagoodies Pinhole! I am torn between ordering one with the unknown of when the next batch will be made or going and trying a few 35 Skopar Pancake 11's. I would be very interested to hear what an image looked like when it was printed up to A3+ or A2 from the Perar.

 

Thanks for posting those images and the set on Flickr. I think your photography may be making up for some of the shortcomings of the lens. I might wait until someone decides that he can re-compute the Tessar ;-}} I still use a period Cooke Triplet in the Meyer Trioplan 105mm f2.8 lens on my Wirgin 6.5 x 9.5 cm field camera c.1910.

Too kind - I think it's a nice little lens. Sorry I can't make a direct comparison with the 35 cron, but the attached give some idea as they're of the same scene (though hugely different light). Main thing is that the tree stump was the place I was focussing on. The 28 Cron Asph renders sharper to my eye (surprise!?), but the little Perar holds up well.

 

re printing, I've not got an image I want to print yet, but I guess that at A3+ - the biggest I can do at home - it'll be pretty good...

A final bit of reviewing. I've posted a set on flickr which give an idea of how the Perar renders texture. most of these at smaller apertures.

Again - very impressed. I'll certainly be holding on to this lens and using it for general purpose travel. Although it won't replace the 35 Summicron IV (:)), it will be really handy to have in the bag when I'm travelling. My preferred kit then is 28 cron / 50 lux / 90 cron. Having this tiny thing to walk about with when I literally only want a camera in a jacket pocket for the off-chance, will be fun.

And if any one's interested, a small set on Flickr which gives an idea of how the Perar renders colour in mixed / low light. Again, I find it pleasing and competent - with no special PP in Lightroom. An example below + the link here:
