Advertisement Posted December 20, 2023 Posted December 20, 2023 Hi Einst_Stein, Take a look here why Q~Q3 are 28mm, not 35 or 24?. I'm sure you'll find what you were looking for!

adan Posted December 21, 2023 Share #4 Posted December 21, 2023 1) Remember that the Q was originally an in-house research project to examine digitally correcting lens output, distortion in particular. The Q "28mm" lens is intentionally designed to natively produce a lot of fisheye distortion (thus keeping it smaller than expected), which the camera firmware straightens out. This was to test the concept, for use in the SL lenses if/where needed (and save size and the amount of optical correction needed in those**). But once the Q got rave reviews from beta testers, it was put into production as its own product line. 2) Most (not all, but most) compact "kit zooms" start at "28mm" - 35mm is passé, and 24 is rare. And that is the ultimate target market for the Q - a high-end FF fixed-lens "camera bag in one camera." As the Q has acquired higher-resolution sensors, a cropping function is available to provide reasonably decent resolution when cropped to 35, 50 and now 75mm framing (similar tech is now available in the M11 60Mp camera). The 2004 Digilux 2 also sported "28-90" framing, and the Q is in some degree the updated Digilux 2 (outstanding f/2-ish fixed lens, EVF in the "M-like" corner location, manual shutter/aperture/focus controls).

Leica did "abuse" the 0.72 M viewfinder - going all the way back to the M4-P - by squeezing in 28mm framelines. And even briefly produced an optional "wide M" 0.58X viewfinder, to make the 28 lines even more visible. _________________ ** This is rumored to be the reason Erwin Puts, an expert on Leica's optical correction genius over the decades, walked away from Leica in his last years.

It may not have ever been stated by Leica in their literature...but it definitely influenced their thinking. I, and many people I know had an iphone in 2015.

Einst_Stein Posted December 21, 2023 Author Share #9 Posted December 21, 2023 (edited) If you compare Leica M summicron or SL summicron, 28mm is not the smallest, nor the cheapest. it is 35mm or 50mm. Size is definitely not the reason of 28mm. Edited December 21, 2023 by Einst_Stein 1 Link to post Share on other sites More sharing options...

Copying from Wikipedia, the iPhone 6 sold 222 millions units worldwide. If that’s not popular to you, I don’t know what could be considered popular. 1 Link to post Share on other sites More sharing options...

A 35mm would require more glass and a bigger footprint and a much heavier camera. Not true. The smallest Summiluxes are the 35mm Summilux and the smallest Summicron is the Summicron 35 (and 40C). My understanding is that Leica wanted to go as wide as possible for a Summilux lens because it opens more possibilities for cropping, resulting in the widest digital zoom range possible. The X range was built around 35mm FL because it is the most compact and also because cropping from 28mm with a 10MP(X1) to 16MP(X2 and later) sensor does not yield enough pixels for 50mm crops (5 - 8 MP as it is now compared to only 3 to 5 MP) I think in the hands of an experienced photographer the 35mm FL fixed lens could work better. The iPhone generation seems to be reluctant to take a step back where needed. My favorite FL is the 40mm, so I would crop away half my pixels most of the time with the Q. Of course, I would just treat it as a 28mm in stead. 28 mm is my least used FL on FF. I will rather go longer or wider like 21mm or 40 mm. IMO there is a lot of potential for a Q variant with a small fixed Summilux 35. I love my X2 and never had the feeling it is not wide enough.

David Wien Posted December 21, 2023 Share #13 Posted December 21, 2023 My favourite lens on the Canon R6 is 16mm: but in investing in a Q3, I am giving Leica the benefit of the doubt regarding 28mm, and so far I am happy. David 1 Link to post Share on other sites More sharing options...

It’s not an issue for me I‘m just pointing it out. Most lenses are not exactly the focal length on the barrel. Many 50 mm lenses are 53 or 54 mm for instance. If you want to calculate the exact focal length of a lens you must measure the angle of view (or measure the focal length on an optical bench.) it may well be that the Q is precise and your 35 and 5 too narrow.
