KWNJr: New lenses for the 645Z?
Will any new lenses cover 6x4.5 sensor size, larger than the existing the existing sensor?
i.e. for full backwards and possible forwards compatibility.

They all cover the original 645 image circle

You may have never heard it but do the math, its the amount of glass and how much cheaper it is to make smaller elements. adding the empty tube makes for the larger lens you don't want so whats the point... unless you're Sigma.

There is one other truth about lens design you may want to know when it comes to wide angle, the larger the front element the smaller the rear elements need to be relative to the front element. It costs less to have 2-4 large front elements and a dozen smaller rear elements then it costs to have them all medium sized elements and its also "usually" easier to design in that way.

And all I'm saying is easier isn't always the truth, for some circumstances it could be quite a bit harder as well. Hey with this Venus lens how about designing it without the need for 4 stops of vignetting, you don't see that many stops of vignetting on a DSLR lens ever.

There isn't an equivalent to the Venus 12mm F2.8 or 15mm F4.0 in mirrorless that have an advantage, there just isn't a match.

@panther fan, you seem to have a big bur up your but for no reason. Good lenses can be made for any mount size just the same as bad lenses. A lot of it depends on how much expense the company wants to put into it and how much money and profit the company wants out of it. A smart company will give their customers the least they can get away with for the highest price they can get away with to maximize profit, so if they design a lens then make it cheaper by allowing for certain aberration or other weaknesses that they feel their customers are willing to put up with then they will. This doesn't change the fact that for some reasons in certain ways it can be harder to design a high quality wide angle lens for a shorter flange distance however a company also has to balance that with the cost of materials too. Its never black and white so get that bur out of your butt and chill out not all smaller UWA lenses for mirrorless are better, you chose some that are and there are others that aren't

Take what they say with a huge grain of salt unless you are knowledgeable on the topic they're discussing (that and if they are as well!) if you don't know lens design then you may misunderstand or be fooled by fancy talk. If they aren't the chief lens designer then they may be misrepresenting something they may have heard and just saying things that sound good. Even if they were correct in what they were saying then ask yourself better how? size? weight? price? cost to them? or because the market is moving that direction? Nobody pointed out a patent for those same lens specifications by Sigma for mirrorless so how do they know it would be better if designed for mirrorless unless they already tried to design them for mirrorless and had they already tried a patent would pop up if not already then very soon (definitely unlikely until they're ready to make such a lens).

@panther fan Yes they say that but they'll say anything to drive prestige and sales.

@Max Iso As for short flange distance lenses performing better, well it depends on the design. A lens design could be aided by more elements to correct aberrations, those elements could be put where the mirror box used to be and therefore improve the design without making the lens larger or much larger. A lens could also be over designed for a larger image circle then employ a speed booster set of elements in the space where the mirror box used to be improving the overall resolution and minimizing some of the aberrations. None of these are guarantees, a poorly designed lens will always be a poorly designed lens regardless of flange distance.

Yes they are harder to design because of the angle of incidence but easier to make smaller as you have more room for the elements closer to the sensor... like with everything in photography, for every advantage there is a countering disadvantage.

@Max Iso, who needs AF with an ultra-wide lens? Maybe someone who doesn't understand the distance scale!

@CekariYH Yes I should say you don't need to stop down to F11 for best results, its just my preferred aperture for landscape and architecture and the sort... However that doesn't mean I won't use it at F2.8 when I'm being creative either. And yes the hyper focal distance is a great tool

Yes if you've ever done or dabbled in lens design you know that often as you correct for barrel distortion in a wide angle lens it increases the field curvature, if you correct the field curvature you get barrel distortion. The best compromise may be in the 2-3% barrel distortion range (that is of course just my opinion) I have the Venus 12mm F2.8 Zero-Distortion lens for FF, I love it, it is great, however I don't shoot it at F2.8, more often i'm at F11, F11 on a brick wall test will still show poor corners compared with the center however in real life shooting its perfectly fine, What bugs me more about this one is the massive vignetting, they could have done better.

Akpinxit: I feel that horizontal correction needed , otherwise nice photo

I spot this readily too however in this case the fade out on the left and the mustache distortion may actually be affecting your judgement on this one.

Isn't it great then that God has enough grace and love to forgive us all of our sins even the ones we didn't know we committed!

The only thing God made us is the ability to have free choice, he did not make us bad, he gave us the choice to be bad or not. He also gave us the opportunity to turn away from our bad ways try to be the best we can be knowing full well that we are not perfect and will continue to sin. It is not by works or by being good that we can be saved, It is only by his grace. I'm not going to tell you what or who to believe thats up to you, just be careful to avoid misrepresenting Christianity. Thanks

tailings: I saw this article a few days ago. Yes, it's sad the tree was damaged/vandalized and further unfortunate the park decided the damage warranted the removal of the entire tree. Yet, I didn't see anything to definitively say the tree was intentionally vandalized because of its fame as 'The Broccoli Tree'. Yes, it's very plausible but nonetheless it is not a foregone conclusion that the tree was vandalized because of its popularity on social media.

Though I think the counter argument about its destruction not being related to its fame is weak. I see it from a different point, cut down that one limb and a week later another limb would have a deep cut in it and the vandalism continues until it reaches the current state.

I don't think there is a distinction between social media and and humanity being inherently evil, they're one in the same. Just what evil invented social media... yes it too was humanity!
