Regarding what #2 said about "Just saw this and figured i’d share my..." - skip the stress! Grab the Sony FE 35mm f1.8. Super reliable! Amazing AF! You wont regret it!

Man, you're gonna love the 35mm focal length for Seattle! It's perfect for those rainy street vibes and tight alleyways. Honestly, you do not need to blow your whole $1200 budget to get incredible results. I've shot with the Sigma 35mm f1.4 DG DN Art and it is a total beast! The MTF charts on this thing are insane and the autofocus speed on the A7III is fantastic... dont let the forum nerds scare you away. It's way cheaper than the GM and the image quality is basically identical in the center. If you want to save even more cash and keep your kit light for travel, grab the Sony FE 35mm f1.8. It's tiny, super sharp, and those linear motors mean it focuses instantly. Use the extra money for a nice circular polarizer or some good seafood while you're there!

Saw this earlier and wanted to chime in because i have had some real headaches with gear before big trips. Honestly, i have been pretty disappointed with how some of the cheaper alternatives perform when things get hectic. I tried to save some cash once for a trip, and unfortunately, the focus just wasnt as snappy as i needed for street stuff. It felt like such a waste of a trip when half my candids were just slightly off. I usually like to fix things myself and handle my own gear maintenance, but you cant really diy a better autofocus motor when it fails you in the field... it was a huge letdown. If you want some cool spots to test whatever you buy, skip Pike Place and maybe check out the Ballard Locks or some of the industrial spots in Georgetown for those gritty street vibes. Georgetown has some really cool textures that look great with a fast prime. Before you pull the trigger, what kind of weather are you expecting to shoot in? Also, are you more of a one-lens-for-the-whole-day kind of person or are you okay with swapping things out if the light changes?

> Is the GM glass really worth the premium for someone who isnt doing professional studio work every day? Quick reply while I have a sec... honestly I have been super satisfied just sticking with the native Sony lenses. You cant really go wrong there. I am a big believer in the reliability factor... especially when you are traveling and dont want to fiddle with settings or worry about how the lens is gonna talk to the body. Just pick up any of the Sony branded primes that fits your budget. They are built so well and the autofocus is basically flawless in my experience. I have had zero complaints with mine over the years. They just work every single time which is what you want when you are out exploring a new city. Go Sony and you wont regret it, seriously.

Just saw this and figured i’d share my own headache from last year. I was basically in your shoes right before a big trip and i ended up overthinking the technical specs so much i forgot about how the lens actually feels to carry... it’s a total trap. I once had a really expensive, fast prime and honestly? I kind of hated using it for travel. It was just a beast to lug around. Here is what i learned from that mess:

• The weight balance on the Sony Alpha a7 III matters way more than people say. If the lens is too heavy, the camera tilts forward on your strap and hits your hip all day. It gets old really fast.
• Be careful with those ultra-wide apertures. Shooting street at f1.4 is cool until you realize half your shots are slightly out of focus because people are moving and the depth of field is paper thin.
• Make sure to check the weather sealing. Seattle is constant mist and i’ve seen people ruin glass because they thought moisture resistant meant waterproof. I actually swapped a heavy setup for a much smaller one because the weight was making me not want to take the camera out of the bag. The grass isnt always greener on the high-end side, especially if you're walking 10 miles a day. I would suggest really looking at the physical size before you hit buy because a heavy setup makes you lazy way faster than a zoom lens does. I spent way too much time worrying about bokeh and not enough about my actual comfort while walking.

Been thinking about your situation for a few hours because I went through this exact same paralysis before my last big trip! Regarding what #1 said about "Man, you're gonna love the 35mm focal length...", he is spot on. 35mm is basically the perfect storyteller lens for a city like Seattle. I spent years switching between native glass and third-party options, and here is how they stacked up in my kit:

• Sony FE 35mm f1.4 GM: This is the gold standard for a reason! It is incredibly light and the autofocus is basically instantaneous. I love how it handles the rain and humidity with that top-tier weather sealing. It fits perfectly in your budget if you find a good deal!
• Sigma 35mm f1.4 DG DN Art: Honestly, the image quality is breathtaking. It has this unique contrast that I sometimes prefer over the Sony. The main trade-off I found was the weight; it is definitely chunkier than the GM, which matters if you are walking ten miles a day through Pike Place Market.
• Sony FE 35mm f1.8: Dont sleep on this little beast! It is tiny, fast, and leaves you with extra cash for great coffee in Seattle. The bokeh isnt as creamy as the f1.4 glass, but it gets the job done beautifully! Go with your gut and dont look back! The A7III is still a beast and will handle any of these like a champ!

Caught this thread a bit late but honestly, after four years on an A7III, I've found that most primes in that $1200 range still have disappointing corner sharpness when you look at the raw MTF data. I had issues with edge distortion on a few of those high-end units during my last trip. Unfortunately, the glass quality just doesnt compensate for the weight when you're dealing with logistics. Actually, speaking of logistics, the last time I flew into Sea-Tac for a shoot, TSA held me up forever because of my battery cases.

• They thought the metal casing was suspicious
• The line was like forty minutes long
• I almost missed my rental car pickup Then the rental place didnt even have the mid-size I booked so I ended up with this tiny hatchback that barely fit my tripod. Anyway lol. Sorry kinda went off topic there.
