New 28mm 2.8 ZM and M8

[MP Guy]

I received my new biogon 28 from Tony today. It is very small. It looks very well built and feels solid. Not as solid feeling as the Leica lens but solid enough to save the $$'s. The finish is awesome and compliments my chrome M's very well. Focus is smooth as butter and a joy to work with. Attached are some sample shots I did today. Nothing fancey but just to give you a general idea of its capabilities.

They are in the M8 gallery as well.

Jorge,

Are you happy with the corner to corner sharpness (it's hard to tell on a computer monitor from a JPEG)?

I guess it would be more instructive for us film shooters for you to give us an idea of corner to corner sharpness on full frame 35mm vs cropped digital (of course the lens' true coverage won't be shown).

I am very happy with the edgre to edge sharpness. If you want to see a full size image no cropping here is a link to the pig picture. It is 8 megs.

when does it compare with the new elmarit 28 asph?

Jorge, the red neon lettering has a sawtooth pattern on my monitor at home and at work. Is this in your original?

I have held off on the Biogon because the MTF data indicates a falloff in performance at the edges of the frame that is more dramatic than on the other ZM lenses. Are you planning to use this lens on film? It would be an interesting comparison.

Best wishes

Jorge:

I purchased the 28 about 2 weeks ago, and for the $$$$ it is a great performer. As far as the MTF data in my opinion we're splitting hairs and we've all been reading too much of Erwin lately.

Without a loop and serious review I don't feel the falloff is as dramatic as it may seem 🙂

I'll post some pics shot with film for comparison....

The zigzag neon looks like an image artifact. You can see it better here:

very nice photos Jorge, how is the size compared to say a Rokkor 40/2 ?

Jorge,

What 6-bit coding are you going to put on this Zeiss lens and how are you going to do it?

I'm also searching for the appropriate 6-bit coding to place on my ZM 25mm and for some one to do it professionally?

Zeiss is still studying the issue...

I remember back a while ago Jorge was talking about finding some way to do 6 bit as a service through the forum or something, wonder if anything happened out of that.

Remember when you teased us with this service, Jorge?

 

[MP Guy]

Yes I do. I am waiting to hear back on some legal questions which will give me a go or no go.

Jorge, I don't see the 28/2.8 ZM in your sig. Have you already gotten rid of it or have you just not had a chance to update it? Just curious.

Dan,

The M8 has a 1,3 crop factor sensor. So, any edge problem, - I hardly think there is one with a Zeiss 28 mm, is cut away. And even though M8 uses only the best part of the optics it still hasn't a sensor good enough to compromise any fairly good M-lense.
