Most compact set for Sony A7

Hi there,

I recently purchased a Leica Elmarit-M 28mm for my Sony A7 and I absolutely love the image and small form factor.

Now I'm looking for a complete set to travel the world with.
My favorite focal lengths would be 21mm, 28mm, 50mm and 85mm.
Unfortunately I can't afford to go all Leica on all of those 4 lenses.

Is there a cheaper alternative that makes a really good and especially compact set?

I think rangefinder lenses are the way to go to save as much space and weight as possible.
Although I thought about Olympus OM Zuiko lenses as well but the adapter itself is already pretty big.

Thanks

Zeiss M lenses.
Voigtlander is also compact, 35/1.4 or 40/1.4.
Canon ltm 50/1.8 or 50/1.4.
Zeiss Contax G lenses if you got a good adapter. 35/2 and 90/2.8 is awesome. 21/2.8 gives color shift in the corners.
Leica/Minolta ltm 90/4 is often preferred instead of contax g 90/2.8.
Sony 28/2, zeiss 35/2.8 these are AF.

You don't mention what kind of pictures you want to take. You won't use the same lens for available light pictures of people in a dark interior and landscape pictures taken in bright sunlight.

If you are looking for quality lenses, compact and cheaper than Leica, you might want to check Cosina/Voigländer products.

21mm is difficult, as most rangefinder ultrawide lenses do not play well with the A7 sensor. The Ultron 21/1.8 gives good results but it is neither compact nor light. Old SLR ultrawide lenses are usually quite bulky when you factor in their adapters and often disappointing when used on high resolution sensors. The Zeiss Loxia 21/2.8 is great lens but it is really expensive and not so compact... If you really want a tiny lens, the Color Skopar 21/4 is hard to beat. It suffers from color casts (correctable) and smearing in the corners but image quality improves when the lens is stopped down at least to F/11. Check the really nice pictures taken by fellow member Kuuan on this thread: http://forum.mflenses.com/voigtlaender-color-skopar-f4-21mm-t68947.html

I prefer 40mm over 28+50mm, so I would suggest either the Leica/Minolta Summicron/Rokkor 40/2 (nice lens, small and affordable -especially when branded Minolta) or the Nokton 40/1.4 (faster lens but a bit more quirky than the Leica/Minolta).

As for a short tele, I really love the Apo-Lanthar 90/3.5, which is compact and sharp as a tack. There is a version in Leica mount and another one available in various SLR mounts. I prefer the SLR version, because it focuses closer and reaches 1:4 ratio out of the box (try to get it in Pentax or Nikon mount, since it has a real aperture ring, contrary to the one in Canon mount). But it might be easier in your case to get the Leica Mount version so you don't have to carry a different adapter. If you use a Leica adapter with built-in helicoid, it will help to focus closer.

A full kit with Color Skopar 21/4, Summicron/Rokkor 40/2 and Apo-Lanthar 90/3.5 would fit in a ridiculously small bag and shouldn't cost you a fortune if you buy used lenses and shop carefully.

Cheers!

Abbazz

Hi, Leica Elmar 50/2,8 collapsible is not so expensive as other Leicas. (Or Elmar-M more cost and more lQ.)

Tiny as possible. I bought one this week.

Any of these Leica M with a techart auto focus adaptor... compact and super performance... unfortunately, you would need the A7ii A7Rii or A6300

For ultra wide Minolta 20mm f 2.8 is very compact but you have the long adaptor

Thanks for the replies.

The Voigtlander lenses look great.
Is there a website that lists all of them. There must be older ones as well, right?
All I found ist this: https://voigtlaender.com/vm-mount.html

Right! Here is the best information site about all RF Voigtlander lenses ever produced by Cosina:
https://www.cameraquest.com/voigtlen.htm

BTW, I am a big fan of those lenses.
Here is my little collection: http://forum.mflenses.com/voigtlander-lens-porn-t72412.html

You have to be careful . Rengefinder lenses , especially UWA WA , have usually a poor performance in the corners with the A7 ( corner smearing, color cast).
What about your Leitz 28mm?
Regarding modern rangefinder standard lenses I would consider the Nokton 40 1.4 which I like very much.
For 50mm have a look at Zeiss Planar 50 f2 M mount.

For longer focal lengths, the RF lenses have no theoritical advantage to the SLR ones when it comes to the size.
They will be simply slower ( lens diameter cannot be too big).
For compactness, quality and price , in my opinion nothing beats the Zeiss Sonnar 85 2.8 . It is a stupidly cheap lens.
It exists in Rollei QBM version really tiny ( 49mm filter diameter) and in Contax Yashica mount.

That's right. Therefore you should rather go for the newest UWA's to avoid such troubles. Obviously they found a solution to overcome the lousy A7 performance (caused by the thick filter stack on top of the sensor) with such lenses.

Alternatively you may have a look into this: https://kolarivision.com/product/sony-a7-series-thin-filter-legacy-lens-upgrade/

Unless you wish to peruse the NEX pancake lenses, or the M-AF plastic zooms (35-80 II/N or 35-105 II/N),..

what comes to my mind is the "Small Bauble", 55/1.8.
Mine is labeled Revueflex, but it is probably a relabel of a famous brand.
Very small, nice IQ.

The plastic zooms I mentioned aren't really top-notch. Their main point is their range in such a small package. If you don't have the M-AF adaptor already I would pass on these.

Agreed. They also adapt easily to Leica-M, so you can keep an FE-LM adaptor on the body, and just have smaller OM-LM adaptors on the OM lenses.

The wide angles are such a problem on the Sony's that I would just spend your most of your budget on the 21/2.8 Zeiss Loxia.. You have the 28 elmarit already.. if you don't, the 28/2 Sony autofocus is actually a decent compact lens that is not very expensive.. for a 50mm there are a TON of cheap options.. I personally like Canon Rangefinder 50's.. they are super cheap, compact and can give you a modern look or vintage depending on what you prefer. The 85's.. Jupiter-9, Nikkor-P.C. 85/2 are good, cheap and fairly compact.. The Zeiss contax G 90/2.8 is a great lens for cheap too.. I'd probably go for the Zeiss here.

The kolari mod should only be done if you plan on never using Native Sony glass or vintage slr wide angles because the side effect is that it smears some of those.

It's only some of the rangefinder wides. OM wides work fine, for example. Olympus Zuiko 21/3.5 is compact and works great, no corner issues. Loxia 21/2.8 is a great lens, but completely different ballpark, price-wise.
