As has been revealed a number of times already, 'compact and lightweight' very well applies to the description of the body ALONE,
but after you mount the appropriate lens on the body, the total distance from back of body to front of lens often ends up longer for the mirrorless camera.

there may be a handful of lenses that are the exception to the rules, but implying that mirrorless is similar in size with comparable dslr setups is false.

I have a compact kit as well as a heavy kit. DSLR's have no compact kits.... and of course the body matters too. Compare the A9 vs 1Dx. Now multiply by two if you're an event/dual body shooter.


Sony A7rii/A7riii - FE 12-24/4 - FE 24-240 - FE 28/2 - FE 35/2.8 - CV 35/1.7 - FE 50/1.8 - FE 85/1.8 - EF 135/1.8 Art - F 600/5.6 - CZ 35-70, 100-300 - Astro Rok 14/2.8, 24/1.4 - Tamron 28-75 f2.8, 70-200 f2.8 VC

My point exactly, that size/weight are not the reasons for the switch to FF mirrorless (vs FF dSLR). Size and weight are the reason for switching to micro 4/3 format.

There are other reasons to consider mirrorless, which are real and valid pros. Having to sum six lenses in order to arrive at 16 oz. of benefit is hardly a reason. Sony's own product information does not mention any size/weight advantage for the A9.

A few months ago I had calculated what a FF dSLR kit with lenses weighed vs. the FF mirrorless kit. In specifically discussing the new Sony A9, I had determined that if you buy same FL and same max aperture in FF mirrorless or FF dSLR, there will be little benefit in lens size...only 2 of six lenses were shorter than the Canon lens equivalent. In overall kit weight you save only about 10% in weight of mirrorless FF vs. dSLR FF sensor when the kit had comparable same 6 lenses in both kits.

One truly has a size advantage if one goes from FF dSLR to an APS-C mirrorless or 4/3 format mirrorless, as the needed FL are proportionately shorter for the same AOV.

Even on APS-C, the differences aren't that great when you start to talk about longer and/or faster lenses. That's before you consider than an f/2.8 lens on APS-C is more like an f/4 lens on full frame. For example, the Fuji 50-140 is smaller and lighter than the Canon 70-200 2.8 but bigger and heavier than the f/4 version which its aperture more directly compares to.

Sony's full frame zooms are just as big and heavy as Canon or Nikons which is why I've never considered them. I've owned a Fuji and it's a nice system for many applications, but you can't cheat physics. If you need the light gathering capability of a large sensor, you'll need a big piece of glass in front of it.

If money isn't an option the new Leica M 10 is a lot smaller as are Leica M lenses. Not a lot lighter though.

it may not be for you, but I can shoot my A7rii + FE 35 all day, and do most of the time. If you really want a small kit, you can certainly source one, but seeing that you linked the petapixel clickbait, you're not really interested in honest answers. Your "kit" assumption, assumes that one must carry more than one lens at once amiright? For the most part, I dont need more than one lens for most of my shooting.

What you hand pick for kit comparisons, may not ring true for others. I travel with two bodies, in the past, a 5D and 6D. That alone would put me over 400+ grams, AND not as feature rich, not to mention the volume included is significant, especially to bystanders who may be photographed.

Everyone has a different shooting scenario, and please find me an alternative to the A7rii + FE 35, my daily carry. My second most used is the A7rii + Voigtlander 35 F1.7 + TAP adapter for AF.

My micro kit can fit into the ILC50 by lowepro, and I clip on my belt. My medium sized kit with the voigtlander can fit into the think tank digital holster 5, clipped onto belt.

A 5D series body alone, without lens, would not fit into either of the bags. So you can pretend that the size doesnt matter, and it may not to you, but it certainly does matter. For some folks, even the A7rii + FE 35 is TOO BIG, so they may shoot with a high end point and shoot like the RX 100. Before going to mirrorless, I was a daily DLSR carrying shooter, my small kit is dramatically smaller. Sometimes when I shoot events with fast primes, then only 2/3 primes would be significantly smaller than DSLR equivalents. Sometimes I use my 2.8 zooms, and size savings is even less. Carry out the 600, and the lens weighs much more than the body that it makes little difference what's mounted to the lens.

Perfect. Working DoF scales ROCK. I will never go back to auto focus.

Didn't know AF was necessary to making great photographs. Oh yeah thats right it's not.

Which 35mm FE? On the Sony platform the 35mm 2.8 FE is a great small option, but as soon as you want larger apertures such as 1.4 or better, than lenses become massive and don't balance well with the camera IMO. It's still 2.8, and Sony doesn't have a compact 35mm f2 or better with AF. The best you can do is the 28mm f2 or 55mm 1.8

I tried Sony and now am considering coming back to Canon. The Sony body is smaller and a few hundred grams lighter, but:

-Camera takes a few seconds to "wake up", extremely annoying if it went to sleep and you want to grab a quick shot
-Eats through batteries
-Add a flash and larger lenses and your size/weight advantage disappears.
-While the WYSIWG ability of the viewfinder is nice, the electronic viewfinder isn't the same as optical
-Sony lenses are stupid expensive

Not saying it's a bad system, but know the pros and cons. Fuji has a great system, small with smallish lenses, great build quality etc. If you're okay with crop, that's the direction i'd lean. The XPro-2 has a hybrid optical/electronic viewfinder and their jpg/film simulations are great.

I know Sony has the best DR, best specs, etc. but I just don't love shooting with it. As others have mentioned it feels more like a computer than camera. Fuji is great and even with the hybrid viewfinder has nice ergonomics, size, etc.

you've listed the 28f2, 35 f2.8, and 55 f1.8

what does the Canon DSLR equivalent look like?
28mm f1.8 USM is much bigger and heavier, no IS
50mm f1.8 STM is smaller and lighter. It's also not optically close, no IS
40mm STM, while the lens is technically smaller, it weighs about the same I think, doesnt have IS
35mm F2 IS, that's the lens you want, faster aperture, much bigger, then that's what you should shoot then.

when it comes to Fuji,I'll just say that they dont have a monopoly on small lenses. Many lenses wont compete head to head with a FE lens, and consider the IBIS factor, and sony pulls ahead with comparable lenses. The 16 f1.4, 23 f2, 35 f1.4, 56 f1.2, 16-55 f2.8, 50-140 f2.8 all have something in common. They're either bigger and/or heavier than the FE equivalent. Both brands do offer unique lenses that the other may not have an answer to. Both brands offer small lenses that in combination with camera, offer significant size and weight savings. Sony is generally quite a bit more expensive.

I think you were thinking of the a9 line and not the a99ii . . . the a99ii is an a-mount body, and it noticeably smaller/lighter than the competing 5Div and D8xx series.

We need not get into any extended debates. I will simply make this point about comparative sizes of FF dSLR vs. FF mirrorless:


  • Sony A99V 810g,
    Sony A99-II 849g
    Canon 6DII 765g
  • Sony A99V 147L × 111.2H × 78.4D mm,
    Sony A99-II 142.6L x 104.2H x 76.1D mm
    Canon 6DII 144L x 110.5H x 74.8D mm

  • Sony 28-75mm f/2.8 Sony specifies 3-1/8 " diameter x 3-3/4" extension from flange.
  • Tamron 28-75mm f/2.8 Manufacturer Spec Size 2.87" diam x 3.62”


I see no clearcut intrinsic advantage.

What an interesting comparison.

I wonder if any a99ii shooters would really use that Sony 28-70 for their 42mp sensor? Tamron made that 28-70 in a-mount, IIRC.

A99ii shooters probably never considered the 6Dii, and 6Dii shooters probably never considered the a99ii.

The Sony's ability to stabilize all lenses is something Canon an Nikon don't offer in DSLR bodies. No tripod (extra bulk and weight) needed to shoot 1/30 SS with a fast 135.

For those that say there is no weight advantage using FF mirrorless, I think you really never tried to build up a light system.

I just got back from 3 weeks in Morocco with 2 cameras ( A7R2 and A7R ) and 2 lenses ( Batis 25 and 85)

Try creating an equivalent DSLR outfit and see if you want to carry that outfit for 3 weeks throughout Morocco.
